Good Afternoon!
My PC running Windows XP Professional has caught something nasty! I know next to nothing about fixing this type of thing and really need some help.
First off, AVG found the following problems yet can't seem to do anything about them:
SHeur2.KSW, Generic_C.ABVX and Fake Alert.EV as Trojan Horses
Downloader.Tibs as a Virus

One of the infected files that keeps popping up is named ahtm.htm (more on that further down)

The computer is having a few specific issues:
1. The background image has changed to "Warning Your System is infected." I managed to change it all black but can't change it to anything else. The image selected in the background menu is "ahtm.htm"
2. Every time I open a folder or new window (such as My Documents), Internet Explorer pops open to a web address that starts with "lsp" and says my computer is infected
3. When using Internet Explorer, google search results appear to be fine, but once I click on them I get rerouted to various advertisements.
4. Some mysterious program in my task bar is telling me I need to install antivirus because my computer is at risk.

I tried running Malwarebytes' program but I received an "invalid floating object" error on the screen, which then replicated itself 25 times, one of top of the other. Please help! :thumbsup:

Try running MalwareBytes AntiMalware in safe mode.
