Pc infected

Desktop running windows XP home is infected. When I try to get on fire fox I get a message that I am infected. I also keep getting a security warning that application cannot be executed. The Wuauct exe is infected.I also keep getting another warning box popping up That says anti software alert,Infiltration alert. I ran Malwarebytes in safe mode and did a quick scan and one item came up which I removed. I rebooted then ran another full scan. IT didn't detect anything so I rebooted in normal mode. I was unable to open Malwarebytes program and the same messages above still popped up. Please help!!!

Please post the MBAM (Malwarebytes Antimalware) log that shows what was removed.

It sounds like you have one of the fake antivirus program infections.

Try having a look at the following link: Virus, Spyware, & Malware Removal Guides

If you do find the appropriate guide, follow the instructions closely. Ensure that you do update the MBAM database definitions.

The MBAM log is automatically saved and can be viewed by clicking the Logs tab in MBAM. Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
