How to Remove Win32: Trojan-Gen

The Win32 Trojan-Gen virus is a Trojan horse that is installed on your computer when you download an infected video codec or open an infected email attachment. The Trojan will install several new programs on your computer that cause pop-up advertisements to appear on your screen and even turn off your firewall. Because the Win32 Trojan-Gen infects so many areas of your computer and because it has characteristics both of a virus and a spyware program, the best way to remove it is to run both an anti-virus and an anti-malware utility.

Things You'll Need

• Virus removal utility
• Malware removal utility

Instructions

1. Open your Web browser and navigate to a website where you can download a free anti-virus program. Free options include, AVG, Avast and Avira (see Resources). Download and install the anti-virus program of your chose.

2. Navigate to another website that offers an anti-malware program. Free programs that you can download include Malware Bytes, Avira AntiVir and Microsoft Security Essentials (see Resources). Download and install the anti-malware program of your choice.

3. Click the Windows "Start" menu, right-click on "Computer" and select "Properties." Click the "System Protection" link in the navigation pane on the left. Click "Configure," select "Turn Off System Protection" and choose "OK."

4. Launch the anti-virus program you downloaded earlier. Update the program's virus detection information by clicking on a button that says "Update Now" or something similar.

5. When it is done updating, click "Scan Computer" button. Due a thorough scan rather than a quick scan, and tell the program to remove any problems that it finds. When the scan is done, close the program.

6. Launch the anti-malware program. Run the program's updater utility and click the "Scan" button. Wait for the scan to finish and choose to remove any malware that was found. Restart your computer to finish removing the Win32 Trojan Gen virus.

7. Turn System Restore back using the same steps you used to turn it off.

Tips & Warnings

• Always update your anti-virus programs at least once a week to make sure you have the most recent virus scanning algorithms.

• If you leave the System Restore option on, your computer will make a new restore point as soon as you start the virus scan. The new restore point will have a copy of the Win32 Trojan Gen virus, which could potentially infect your system again.
