What is a Driver?

A driver is a program that is able to control a device that is connected to your computer. These drivers are used by the operating system to enable it to communicate with the particular device the driver was made for. Devices that you connect to your computer are often very specialized which makes it so Windows can not communicate directly with the device without a program telling it how to. This program, or device driver, acts as a translator between the installed device and the programs that utilize the device.

Why do I need to update?

By default Windows contains generic drivers for many different types of hardware connected to your computer. Unfortunately, many of these drivers that are bundled with Windows tend to be generic and do not support all of the advanced features of the hardware being installed. Therefore you would want to download and install the driver created by the hardware manufacturer so that Windows understands how to use these special features.

Also as time goes by, hardware manufacturers release new versions of their drivers to fix bugs, increase performance, increase stability on your computer, or add new features. When these drivers are released it is recommended that you upgrade your driver to take advantage of these new enhancements.

When new drivers are released they tend to come in two types of updates. The first type is a program that you run that will automatically update the driver for you and then prompt you to reboot your computer. The second type is a set of driver files that you need to manually update the drivers with. This tutorial will focus on teaching you how to upgrade your driver using both methods.

Finding Out the Manufacturer and Model of Your Device

Before we begin updating your driver, we need to know the manufacturer and model number for the device. This is a pretty simple problem to overcome. Simply look at your device for a brand name, and that should be the manufacturer. For example I am looking at my modem and on the top it says “Binatone”. Pretty simple huh!

To find the “model” of your device look at the back/bottom of your device for a code (my modem’s is ADSL 2000). If this does not work, try looking in the paperwork that came with your device and see if you can find it there.

On the other hand, if you have an internal device that is not easily accessible, it may be difficult for you to find the make and model for it (for example a video card). For internal devices you should use the Device Manager to find out this information:

Click on the Start button in the bottom right hand corner of your desktop as shown below:

Click on the Control Panel menu option to open the Control Pane as shown below:

Double-click on the System icon as shown below:

Click on the Hardware tab at the top of the box (red arrow), then click on the box which says Device Manager (blue arrow) as shown below:

A window will appear which contains a list of the devices on your computer like the image below.

You will need to click on the plus (+) arrow next to the hardware category for the driver you want to update (red arrow). For my continuing example of updating a video driver I would click on the plus (+) arrow next to display adapters (where video cards reside). After clicking on the (+) sign, the category will open listing the devices that are installed on your computer that fall under this category of hardware. You should see your video card listed and you would make a note of the make and model of the card you wish to update. Stay in the current window, as the following steps will continue from here.

Determining the current version of your driver

Before you upgrade your driver, you want to determine whether or not you have the latest version. When developers create drivers they assign a version number to it. Each time the manufacturer releases a new update to this driver, they increase the version number. In this way you can determine if you have the latest version of the driver by comparing the version number of your currently installed driver to the version number of the driver currently . So if there version number is higher than yours, you know that there is a newer version available for download.

To determine the current version of your driver you would do the following:

While in the device manager, as described above, you need to click on the (+) arrow next to the category of device you want to update (red arrow). Then right click on the device which you would like the update. Again, in my example I would right click on the Radeon 9500 pro / 9700 which the blue arrow is pointing at.

After right clicking a list of options will appear. Click properties:

A new windows will open, which will display the various properties of your device. Click on the Driver tab in the top of the window (red arrow). Then look at the details in the Driver Version line (blue arrow):

Write down this version number so you can reference it later.

Finding the latest driver

So, now that you know the name, model, and version number of your device it is time to determine if there is a newer driver available for you to use. The easiest way to find a updated driver is to check the manufacturer’s web site. This will ensure you have the latest and most up-to-date drivers available for your device. Finding your manufacturers web site should be pretty simple. Using the example above, I found my device manufacturer for my video card was ATI radeon. Usually the manufacturer’s web site is its name with standard internet tags around the end (www. and .com). If you are unable to find the website this way, try going to www.google.com and searching for the name there. Usually the first entry should be the official manufacturer’s site:

When you find the address of the manufacturer, go to the site and have a look around. It would be impossible to give instructions for each manufacturer, but you should be looking for a drivers page. On some manufacturer’s sites the Drivers link is prominent. On others you generally need to go into their support section to find the updated drivers. If that does not work, you can search for it on the site. After taking a good look around the manufacturer’s site, you should have found the driver section for your device. However, in the event that you are unable to find a driver section, there are a number of handy sites which collect all the drivers available into an alphabetical list by manufacturer name. My favorite is www.driverzone.com. It has an up-to-date list of available drivers, and is very easy for novices to navigate around. This step is the only part of the tutorial where I cannot give you specific instructions; it varies too much from brand to brand.

If you have found the drivers page, simply compare the version number of the driver they have available for download to the version number you retrieved earlier. If their version number is higher, then they have an updated driver for your machine. If it is the same version, then there is no newer driver available.

Downloading the driver update

When you have found driver update for your device that is newer that the one you have installed, simply go back to the manufacturers site/or driverzone, and find the newer driver. Click on the download link to this file and you should be prompted with a download box. If you use Internet Explorer it will look like so:

You should save your driver update download to the desktop. This is so that the file can be easily found later on. To do this, click save and setting the Save In pathname as Desktop (red arrow) and press the Save button.

So now you should have the file placed neatly on your desktop for easy access.

If the files extension is .zip, then the driver will need to be extracted first. This can be done very easily using BleepingComputer’s own tutorial on the subject here:

How to create and extract a ZIP File in Windows ME/XP/2003

How to create and extract a ZIP File in Windows 95/98/2000

You should extract these files to the desktop now. If on the other hand, the file is an executable (ends with .exe), then move on to the next section.

Installing the Driver update

To launch the driver update program you would look for the program that you downloaded or extracted. The setup file should look something like this:

Double-click on the setup file and follow the on screen instructions to install the update. When the driver has finished installing, it will usually prompt you to reboot. Reboot your machine and you should now be using the updated drivers.

If on the other hand, there is no setup.exe file or other executable to run, then you will need to manually update the driver through the Device Manger. Using the previous instructions open the Device Manger. Using the drop down plus (+), open the category of the device you want to update and select the device by clicking on it once to highlight it. Right-click on the device and click Properties. Now click on the Driver tab and then click on the Update Driver button:

A wizard will begin in a new window. If the Wizard asks Can Windows connect to Windows Update to search for software? select the option labeled No, not this time and press the Next button. You will now see a screen similar to the one below.

Click on the option labeled Install from a list of specific location (Advanced) (red arrow). Then click next (blue arrow). A screen will open similar to the one below.

Select the option labeled Don’t search. I will choose the driver to install. (red arrow) and press the Next button. A new screen may come up showing compatible hardware. Simply press the Have Disk button.

Then click on the Browse button and navigate to the folder on your desktop where you extracted the driver files. Once you are navigated to that folder you will see something like below.

You will see a list of .inf files that contain the information about the driver update found in that folder. Select the .inf file (red arrow) and press the Open button (blue arrow). Then press the OK button. You will now see a list of compatible hardware. Select the driver and press the Next button. Windows will copy the updated driver to your system. When it is done, press the Finish button.

You will now be back at the properties page for your device. If you look at the version, you should see that the version number now corresponds to the new driver you just installed. You can now press the Close button and exit the Device Manager.

Conclusion

After following the above instructions, you should be able to update your device drivers. This will be useful for meeting minimum requirements for applications/software, to fix bugs that out-of-date drivers may be causing, or to improve the performance of your hardware. As always, if you have any questions feel free to ask them in the computer help forums.

It is a fact; the Internet is just not a safe place to connect your computer to. There are worms constantly scanning for vulnerable computers to infect, trojans disguised as helpful programs but actually install malicious ones, spyware that reports your activities back to their makers, and hijackers that take control of your web browser and browsing experience. For those people who have been the victim of one of these mentioned infections, removing them and getting your computer back in your control can be a daunting and frustrating experience. The purpose of this article is to teach you how to setup your computer in such a way that you minimize as much as possible the risks of contracting one of these infections. Each step is very easy to do and regardless of your computer experience you will have no trouble following along. It is also important to note that there is not one step listed below that is more important than the other. They are all equally important to keeping your computer safe and secure.

1. Educate yourself and be smart about where you visit and what you click on – Understanding how you can get infected and what to avoid when using the Internet will be the most important step in keeping your computer clean and secure. The majority of people who have infections on their machines were infected due to lack of knowledge and clicking on things that they should not. I will provide a list of actions under this step that you should not do:

1. Do not open attachments from users that you do not know. This is one of the most effective ways for viruses to infect you. If you do not know the user, then simply do not open the email and delete it.

2. Never open an attachment that is a .exe, .pif, .com, or .bat unless you specifically know the file is clean. The majority of these are always bad!

3. If you visit a site and a popup appears saying that your computer is unsafe, ignore it! These are gimicks that are used to make you click on the ad which then can potentially install unwanted malware. For an example of how these types of foistware can be installed on your computer, you should read this article: Foistware, And how to avoid it.

An excellent list that contains a list of antispyware apps that should be avoided and a list of ones that are recommended can be found here: Rogue/Suspect Anti-Spyware Products & Web Sites

4. When a you go to a site and a popup occurs, many times they will make them look like a normal Windows message box in order to trick you into clicking on them. Instead just close them by clicking on the X.

5. Do not visit porn sites! I know some of you may not be happy about this, but the reality is that the majority of spyware and browser
hijackers are put on your computer through porn sites.

6. Do not visit warez sites! Not only is pirated software illegal, but it is a breeding ground for malware.

7. Do not visit crack sites! Many of the cracks include malware in them!

8. If you use P2P software, make sure you are careful about what you open. Malware is all over the P2P networks.

9. Read the license agreement for any software that you install. Many free downloads are offered with spyware and other programs that you DO NOT want on your computer. Reading the agreement may help you to spot them.

2. Use an AntiVirus Software – It is very important that your computer has an antivirus software running on your machine. By having an antivirus program running, files and emails will be scanned as you use them, download them, or open them. If a virus is found in one of the items you are about to use, the antivirus program will stop you from being able to run that program and therefore infect yourself.

See this link for a listing of some online/stand-alone antivirus programs:

Virus, Spyware, and Malware Protection and Removal Resources

3. Update your AntiVirus Software – There is no point running an antivirus program if you do not make sure it has all the latest updates available to it. If you do not update the software, it will not know about any new viruses, trojans, worms, etc that have been released into the wild since you installed the program. Then if a new infection appears in your computer, the antivirus program will not know that it is bad, and not alert you when you run it and become infected. Therefore it is imperative that you update your Antivirus software at least once a week (Even more if you wish) so that you are protected from all the latest threats.

4. Install an Anti-Spyware Program – Just as you installed and use an antivirus program, it is essential these days to use a Spyware protection and removal program. These programs can be used to scan your computer for spyware, dialers, browser hijackers, and other programs that are malicious in nature. The 4 program that we recommend are AVG Anti-Spyware, Spybot – Search and Destroy, and Ad-Aware, and Windows Defender.

A tutorial on using some of these programs can be found below:

Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer
Using Spybot – Search & Destroy to remove Spyware , Malware, and Hijackers

5. Commercial Spyware Removal/Protection Programs – If you feel more comfortable installing a commercial Spyware removal program then we recommend WebRoot’s Spysweeper or Lavasoft’s Ad-Aware Professional. Both are excellent products and a worthy addition to the arsenal of software protecting your computer.

Spysweeper Product Information

6. Occasionally Run Online Virus Scans – Unfortunately not all antivirus programs are created equal. Each program may find infections that other antivirus programs do not and vice-versa. It is therefore recommended that you occasionally run some free online antivirus scanners to make sure that you are not infected with items that your particular antivirus program does not know how to find. Two online scanners that we recommend are:

Kaspersky Web scanner
Trend Micro Housecall

Every once in a while, maybe once every 2 weeks, run one or both of these scanners to see if they find anything that may have been missed by your locally installed antivirus software.

7. Visit Microsoft’s Windows Update Site Frequently – If you are a Windows users you must visit http://www.windowsupdate.com regularly. This site is a Microsoft site that will scan your computer for any patches or updates that are missing from your computer. It will then provide a list of items that it can download and install for you. When visiting the site, if it asks if you would like to install the Windows Update software, allow it to do so and it should only ask you to do this once. When the site is loaded you should then allow it to check for new updates and download any that it finds. If it has you reboot your computer, reboot and when your back at the desktop visit the site again and check for new updates. Repeat this process until there are zero critical updates available. This will ensure your computer has all of the latest security updates available installed on your computer and is secure from any known security holes.

8. Visit the Apple Security Updates Site Frequently – If you are an Apple user then you frequently check the Apple Security Site for any new updates and download them if they are available. Information on finding and downloading the latest updates can be found at the Apple security site that we linked to earlier in this step.

9. Use a Firewall – I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. You may say “Why do I need a firewall?” I have all the latest updates for my programs and operating system, so nobody should be able to hack into my computer”. Unfortunately that reasoning is not valid. Many times hackers discover new security holes in a software or operating system long before the software company does and therefore many people get hacked before a security patch is released. By using a firewall the majority of these security holes will not be accessible as the firewall will block the attempt.

For a tutorial on Firewall’s and a listing of some available ones see the link below: Understanding and Using Firewall’s

10.

Install SpywareBlaster – Many known malicious programs are ActiveX programs that integrate into Internet Explorer. If you use Internet Explorer, then we recommend that you download and install SpywareBlaster. This program will load a huge list of known malicious programs into your computer’s configuration and make it so that you can not run these programs on your computer and therefore become infected.

A tutorial on installing & using this product can be found here:

Using SpywareBlaster to protect your computer from Spyware and Malware

11.

Update your security programs regularly – As always if you do not update your programs, your programs will not be able to find the newest infections that may be racing around the Internet. It is therefore important that you upgrade the software and spyware/virus definitions for a particular program so that they are running the most effectively.

12. Switch to another browser, like Firefox, or make your Internet Explorer more secure – The latest version of Internet Explorer 7 is now shipped with much more secure settings. On the other hand, if you use Internet Explorer 6 there are settings that need to be changed. With that said you have two choices; either make Internet Explorer 6 more secure or switch to another browser like Mozilla Firefox. It’s an excellent browser and is secure right after installing it. You can find more info on switching from Internet Explorer to Firefox here

Switching from Internet Explorer to Firefox

If you decide you would rather continue to use Internet Explorer, then follow these steps to make it more secure:
1. From within Internet Explorer click on the tools menu and then click on Options.
2. Click once on the Security tab
3. Click once on the Internet icon so it becomes highlighted.
4. Click once on the Custom Level button.
1. Change the Download signed ActiveX controls to Prompt
2. Change the Download unsigned ActiveX controls to Disable
3. Change the Initialize and script ActiveX controls not marked as safe to Disable
4. Change the Installation of desktop items to Prompt
5. Change the Launching programs and files in an IFRAME to Prompt
6. Change the Navigate sub-frames across different domains to Prompt
7. When all these settings have been made, click on the OK button.
8. If it prompts you as to whether or not you want to save the settings, press the Yes button.
5. Next press the Apply button and then the OK to exit the Internet Properties page.

By following all these steps you are sure to keep your computer at minimal risk to future infections or hack attempts. This is unfortunately not a fool proof method of securing your computer as new risks are released almost every day, but your susceptibility to these attacks will be diminished greatly.

Once download, Green AV will be configured to start automatically when you login to Windows. Once running it will scan your computer and then list a variety of infections that it will not remove until you purchase the program. These infections, though, are not real and do not exist on your computer. Green AV is only showing them to try and trick you into thinking that there is some sort of infection on your computer.

Green AV screen shot
For more screen shots of this infection click on the image above.
There are a total of 11 images you can view.

When Green AV is installed you will also find your computer filled with various warnings and alerts stating that your computer is infected in some manner. This program will hijack both Internet Explorer and Firefox to randomly display warnings when browsing the web that state your computer is infected and that you should purchase Green AV to protect yourself. The warning in Firefox is “This web site you are visiting has been reported as an attack site and has been blocked based on your security preferences.” and the warning in Internet Explorer is “Your system might be at risk, click here to protect your system with Green AV.”. Green AV will also redirect search results for anything related to Green AV to show custom search results rather than the legitimate one. Last but not least, you will also see constant alerts from the Windows taskbar that state that there is some sort of malicious activity occurring on your computer. These alerts, like web browser hijacks are just another attempt to make you think you are infected and should be ignored.

As you can see, Green AV was created to trick you into purchasing the program by making you think that there is a security risk on your computer. In reality, the security risk is Green AV and the malware that was bundled with it. To remove these programs, please use the guide below.

While the Trojan is running you will be constantly shown security notices on your desktop. These notices will state that there is some type of security risk on your computer and then prompt you to purchase SecurityFighter. The Trojan will also display a window that impersonates the legitimate Windows Security Center. The only difference between the legitimate one and the imposter, is that the Trojan widow will suggest that you purchase SecurityFighter to protect your computer. Just like the fake malware files and results, these security notices are just another trick being used to deceive you into thinking that you have a malware problem.

As you can see, SecurityFighter was designed to scam you out of your money by making you think you are infected. If you have already purchased SecurityFighter, then we suggest that you contact your credit card company and dispute the charges. Regardless of whether or not it is purchased, if you find SecurityFighter on your computer, then please use the following guide to remove it and any related malware from your computer.
