The computer was running ok, but I ran a full scan with Avast Free Antivirus. It found and removed the following problem - Win32:Alureon-FZ, file name C:\Windows\system32\drivers\ipsec.sys.
The Network Diagnostics asks "Would you like Windows to reset the catalog to the default configuration? I have clicked yes, restarted, and the problem is not fixed.
I have Windows XP home edition, SP3. I don't know what other information you would need but please ask and I'll do my best to provide it.
Thanks in advance, Mike
EDIT: Moved from XP to Am I Infected forum ~ Hamluis.
