Terrible program. Slowed my system down to a crawl, and made it randomly blue screen. I had to
reinstall Windows in the end. I traced it back to some weird interaction between BitDefender and
programs that mount/unmount network drives on the fly, such as WebDrive (and perhaps Daemon tools).
Would never install it again - and why would I since it melted my system and wasted a week of my
life?
