FakePAV: How to Fight Back

How Win32/FakePAV Steals Credit Card Information and How to Remove the Trojan

Win32/FakePAV was first detected in 3Q10 and became the second most commonly detected rogue security software family by 4Q10. This video shows how a computer is infected by FakePAV and demonstrates how to terminate its process.

The Win32/FakePAV trojan presents a dialog box similar in appearance to a Microsoft Security Essentials alert, listing one or more nonexistent infections that it claims it cannot remove. It then offers to “install” a trial version of a different security program (actually another part of FakePAV itself), and imitates a rogue security software program scanning process. From this point, the experience is similar to most other rogues: the user is informed they need to buy the full version of the scanner to remove the infections. A computer infected with Win32/FakePAV becomes more difficult to use. In addition to stopping explorer.exe from running, the trojan terminates Task Manager, making it difficult to run any other programs.
