Computer was running slowly, though it's a P4 2.4 w/ 80% free HD space and 256 MB Ram, Win XP Home. I did the basics: Adaware Spybot Tuneup Utilities Defrag Disk Cleanup Virus Scan Highjack This Adaware found 300 items Spybot found 1980 items Tuneup Utilities found a fair amount Defrag took FOREVER Disk Cleanup found a small amount to clean Antivirus found 2 items, then crashed. And crashed again. Antivir (and AVG Beforehand) wouldn't complete scans. Highjack this wouldn't run at all. Kept giving errors. And to top it all off, MSN Messenger will NOT connect, with the firewall off or on. She can surf the web fine, and do most anything, but MSN will not connect. We uninstalled, rebooted, and installed it again...same thing. Any ideas what could be the problems / something else I may have missed? Does this sound like a reformat/OS reinstall? Thanks!
