I have a Dell Dimension 2350. Syestem is Microsoft Windows XP Home Edition, Version 2002 with Service Pack 3. I have McAffee Security Center.
Symptoms: McAfee "M" square on tray will go black sometimes. Mostly I get "Your computer is not fully protected". And it's either a yellow alert (systems guard is not enabled) or it's red and 1. Real time scanning is disabled. 2. Spyware & potentially unwanted program scanning is disabled. 3. IM scanning is disabled. 4. Script scanning is disabled. & 5. Buffer overflow protection is disabled. I will click the "Fix" button and on yellow alert it normally fixes it but red alert gives me a can't fix because of an error.
I also have application hang time that would make a saint cry. I have down loaded AVG whatever from download.com and it has helped, but I cannot get rid of this malware. My McAfee scans show nothing is there. Any help would be appreciated. I started experiencing this problem after using Limewire (which I don't use anymore) but I cannot get rid of the nasty little program. Am at my wit's end, so any help is greatly appreciated.

If what dawgsnkats didn't work, try using Internet Explorer and go to:

Free Virus Scan - Free Antivirus Software | Norton Security Scan

Click "Continue to Symantec Security Check", in the next window click No when asked if you want to close this window, that will bring you to a window where you should click Virus Detection.

Write down exactly anything it finds, then go to: : and do a search for what was found. Symantec usually has a removal tool and/or directions for removing manually. Make sure that you follow the instructions for removal, step by step, especially the part regarding disabling System Restore.
