Trojan Vundo Threat Level:

Trojan Vundo is a trojan that launches annoying popup ads on your computer and secretly download harmful files. Because Trojan Vundo runs tons of popup ads, Trojan Vundo really slows down your computer. Trojan Vundo can be spread through emails containing links to websites that exploit your web browser’s security holes. When you click on a link in a Trojan Vundo-laced email, your web browser, like Internet Explorer, opens a site that silently installs the trojan into your computer. Trojan Vundo may secretly run on every Windows startup.

I don’t know about you, but identity theft and adware aren’t how I like to spend my weekends. So remove Vundo.

Note: In any files I mention above, “%System%” is a variable referring to your PC’s System folder. Maybe you renamed it, but by default your System folder is “C:\Windows\System32″ on Windows XP, “C:\Winnt\System32″ on Windows NT/2000,” or “C:\Windows\System” on Windows 95/98/Me.

“%Program_Files%”, “%ProgramFiles%”, or “%Profile%” is a variable referring to a folder in your PC where applications that aren’t a part of your PC’s operating system are installed by default. You may have changed this folder’s name or moved it, but if you didn’t touch it, find the folder as “C:\Program Files”. If you’re having trouble finding this folder, you can locate it by looking up registry value “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir”.

Also, “%UserProfile%” is a variable referring to your current user’s profile folder. If you’re using Windows NT/2000/XP, by default this is “C:\Documents and Settings\[CURRENT USER]” (e.g., “C:\Documents and Settings\JoeSmith”).
