I'm a former webroot customer that went over to Bitdefender. I guess I should have read these forums.
I installed yesterday and so far everything is running well.
I have had several hangs where scans are running and my PC is frozen. Latest one was the daily scan hung on a system restore file. I deleted the logs because I did have a very serious trojan.
I also saw the Windows certified popups - no big deal.
I hope people that DO have the product and have no issues are not posting messages.
