A few weeks ago, I told you about how my dad encountered some sort of malware masquerading as Microsoft Security Essentials. I used Crossloop to troubleshoot, and accidentally triggered a full-on infection of his PC.
Now I've learned a little more about this malware. Doing business under the name Win32/FakePAV, this app comes to you when an infected Web site downloads it to your PC. Win32/FakePAV eventually launches dialogs that look for all the world like Microsoft Security Essentials and then insists that you have to buy fake anti-virus programs, all the while locking you out of your PC's normal functions.
Keep your anti-virus definitions up to date, people. And I'll reiterate what I consider to be pretty good advice: If you see a virus warning from your security software, don't trust it unless you launched the scan yourself. [via Download Squad]
