This computer is a Windows XP Home Edition with Service Pack 3. It did not have any internet access, and had "fake" antivirus alerts. I had to go into safe mode in order to install MalwareBytes. Running MalwareBytes caught nothing. I then took the hard drive to another computer and slaved it - ran Avira against it and caught:
I then was able to move that drive back to the original computer and boot - now I could install MalwareBytes and Avira - but there is no Internet - I can ping my local router, and I have DNS, but NOTHING beyond the router. All other computers have access to any Internet site, ping, etc. When I try to load MSIE7 (that's what is installed) - it gives an instruction error (a memory overwrite error) and quickly closes down. I've installed an alternative LAN port using USB LAN interface, but still no Internet - (thinking that perhaps the internal LAN port was defective).
I was able to update Avira with the definitions file from CD - ran it in normal mode - no infections found. I could not update MalwareBytes (can't find a definition file to download) - but I do have the most recent version installed. Ran it in normal mode - no infections found. I then installed SuperAntispyware - and installed definitions - and it found nothing, too.
I need some help.
