The computer freezes on 10.6.3 and later due to VirusBarrier…

Mikolaj found that anti-virus programVirusBarrier was the problem.  I haven’t have any problem with Sophos and love it.  That makes Virex, Macafee for Mac, and Symantec known problems to make stability.

Well – it seems I didn’t remove ALL the VirusBarrier files… I used AppZapper, but it didn’t find everything – mainly preferences and preference panes, as well as other things which, so it seems, checked my computer for viruses so thoroughly they made it freeze. When I found them by myself, by checking everything in the Library for everything Intego-related, and thrashed them, the freezing stopped. It’s two weeks now and no freeze at all… Looks like VirusBarier is to blame. Perhaps is it a conflict with some other app on my mac, but I’d beware of installing it on my disk again…
