My university has just rolled out KAV6 to staff & students. Under XP I've had few issues, but under vista I'm having performance problems. I've tried 3 different vista laptops, and all are the same. After installing KAV 6.0.3.837 onto 32-bit Vista SP1, performance goes down the drain. I see huge amounts of disk thrashing & 1 core is inevitably maxed out. That's with File, Mail, Web & proactive defense enabled, scan new files only & scan files/documents by filetype content. If I disable everything except file & proactive defense then everything calms down & the machine is useable again, although I do notice that after a definition update the disk thrashes nicely for about half an hour. Any ideas?

Secondly, I'm having an issue with a false positive. It's a file I've had for a while & run regularly. According to virustotal.com, 3/37 engines detect it as a virus, however none of the registry keys or files that the virus generates are present after running the file, so I'm happy that it's a false positive. How do I get kaspersky to stop bugging me about it? Every so often I get a warning & the option to clean/delete/skip. I choose to skip. I then get a smaller box coming up every few minutes telling me again that it's infected. I can hide that box, although it comes back every day or so. And the event log is jam packed with the error. I've gone into trusted zone/exclusion masks & added the folder to the exclusion masks, but it's still scanning it & talling me it's infected, and still preventing me running the file. How do I stop it bothering me & how do I set it to let me run the file?
