Adrian, Can't speak for Vipre, but if that's the only change you've made, then it's the first to suspect. Have you considered uninstalling it and then running your system and applications for a while to see if there is a significant improvement? I use MS-Essentials, and it appears to be non-intrusive over the year that it's been operating.

Has any other JAWS user installed the Vipre antivirus program? Ever since the latest update, released about two weeks ago, performance on my system has deteriorated. some programs take longer to open, I've had numerous crashes and JAWS is harder, if not impossible, to bring back without rebooting. I have the latest release of JAWS 11 on an XP machine. My major memory hog is Outlook 2003. I've neither installed nor updated any other applications during this time. Any thoughts?
