Hello,
my pc is infected by antivirus pro 2010. I've tried ad aware, but it did'nt found anything. I uninstalled ad aware because aewservice.exe was using all my cpu and I could'nt use my pc (had to shut down this service with ctrl+alt+suppr).

I've tried Spybot search and destroy and he found something.
I dont have anymore Antivirus pro 2010, but my PC is still running slowly. And some applications (Explorer, Internet explorer, acrobat Pdf reader) "block" (I can't close them and can't even restart the computer - had to reset it with the button on the tower).

I've tried Hijackthis 2.0.2 and when I do a system scan + log, I got the following message:This action cannot be completed because the other application is busy. Choose "swith to" to activate the busy application and correct the problem".
And when I click "switch to" it's not working (same message again).

What can i do then ?

I'm using windows Xp sp2

Thank you for your help

fred

Read the instructions in my signature about posting a log in the HijackThis forum. Copy/paste or link to this thread to describe the problem, and somebody there can help you with malware removal. Since you cannot get HijackThis to work, they have other diagnostic tools to try.
