I'm using Windows 8 on a PC. I just upgraded from Bitdefender 2013 AV to 2014. I used the 2013 uninstall tool, then loaded in 2014. I've noticed that if Autoscan is running and I interrupt it, my computer becomes extremely slow in launching any program (about 30 seconds for each launch). This even includes launching Task Manager. The only way to stop the problem is to reboot. I've shut off Autoscan in hopes that the problem goes away.
With the exception of the Bitdefender interface itself, which continues to run very slowly under these circumstances, all other programs run at full speed once their slow launch completes.
Any thoughts on why this is happening? I did try to uninstall AV 2014, but the process got stuck at 50%, and there is no official 2014 uninstall tool yet (I was forced to use a backup image of my C: drive in order to get everything back to normal).
