I have a problem...I loaded Spybot SD, it loaded fine...3 times...but whatever has EXPLORER.EXE running at 80 to 100% all the time, will not let Spybot SD even load to do a scan. The computer shuts down just as Spybot SD starts to fully load. I have only one version of Spybot SD installed....I did uninstall, then reinstall each time...trying to get it to scan...but Im thinking its a trojan. I'll try to load Hijack This....and get you a log....I hope you can help.
