Hi there, still had the same problem as in 522,
"Upon restarting my PC, CPU utilisation went to around 100%, and the KAV systray icon remained grey. I left it for a while but nothing happened. I had to uninstall it from safemode, and then re-install 5.0.388."
I sent the tracelogs to kaspersky support, but received a strange email reply:
"Error processing request:
