I have a Compaq Armada running Windows 2000 and I have been trying to find some type of Antivirus software to work with it without slowing it to turtle speed and today I was scanning it with Adaware and it shut down and now it will only come back up to the windows start up screen and gives me some message stating the registry is not large enough to start the profile, so I cannot get back into the desktop, can somebody help me, PLEASEEEEEEEEEEEEEEEEEEEEE
