Last Updated: October 7, 2022

Antivirus 2009 is a spyware program that disguises itself as a legit anti-virus program. It bombards you with pop-up messages detailing fake scan reports of fake viruses and tries to scare you into entering your credit card information and buying the full version of the program. If your computer has been infected by Antivirus 2009, you can take the following steps to remove it.

Steps

Reboot your computer into Safe Mode with Networking. Reset your computer and repeatedly hit the F8 key until the Advanced Startup menu appears. From here, select Safe Mode with Networking. Safe Mode will allow you to delete the files and registry entries without the program trying to interfere.

- HKEY_CURRENT_USER\Software\Antivirus

First, use the Search function to find the following two files: shlwapi.ddl and wininet.dll. Make note of the locations. Open the Command Prompt and navigate to the first file.^{[1]
