just did an auto update to version 1.50 and ran a quick scan. it found a hijack in registry for start menu logoff. I removed and rebooted. I tried to run another quick scan. It starts but never completes just give me the microsoft "sorry but we have encountered and error and must close" (not the exact wording, but I'm sure u know what msg I referring too) I've tried repeatedly, rebooted and updated virus definitions but still I get this error. I haven't tried the full scan so I don't know if that would work or not. What can I do????? thanks for any help or suggestions
