Malware removal

W32.Qakbot is a worm that spreads through resources shared on a network. Once nestles into your computer, the worm may steal personal information (think Outlook, FTP logins, keystrokes typed, sites visited, etc.), download more badware onto your PC, and allow a hacker to access your system.

DIY W32.Qakbot Removal Instructions

Start by removing the above files. If you're not sure how to do this, refer to the instructions below.

Note: In any files I mention above, “%UserProfile%” is a variable referring to your current user’s profile folder. (Not an iEuphemism for muth@fugg@#*!@.) So if you’re using Windows NT/2000/XP/7, by default this is “C:\Documents and Settings\[CURRENT USER]” (e.g., “C:\Documents and Settings\NoahFence”).
