I have a Windows XP pro system (SP2) which seems to have 86% plus CPU usage by the "System" process at all times - even with no other programs running. Under Task manager another "System" entry seems to pop up and then disappear about every couple of seconds. There also seems to be constant network activity of a few packets about every couple of seconds.
I have run antivirus programs and anti adware programs to no avail ... (norman anti-virus has been running constantly & Spybot S&D (resident) and also tried Ad-Aware).
Any thoughts on what is going on or how to find the "pest" that may have infected this system would be greatly appreciated.
Best regards, Dave Melnyk
