I have a bug on a Windows XP/SP2 laptop that throws this error whenever I open a web page or change to another web page:
System Error!

Your computer was infected by an unknown trojan. It's dangerous for your system (critical files can be lost)!

Click OK to download the antispyware program to clean your system! (Recommended)


I have followed your step by step doc and does these steps:
1) Cleaned out all temp files
2) Ran Adaware + SpyBot
3) Ran Stinger
4) Ran Trend Micro House call (this detected something 'unknown' but could not remove it.
5) XP Firewall is enabled
6) Patches are downloaded
7) I have run HJT and here is the log file:

thanks for any help!

I got it fixed. I uploaded my hijackthis log to http://HijackThis.de and they do an instant analysis.

They flagged this entry

O2 - BHO: Media Player Classic - {486D0362-657B-4771-B56D-AE29AA31B78B} - C:\WINDOWS\ausctv32a.dll

I deleted it with HijackThis (closed all Web Browser windows and Windows Explorer sessions 1st).

I have opened lots of Web Browser sessions and the popup error does not occur anymore....

Thank you Jesus!

Hope that Helps some people.
