The BitDefender services constantly stop. Sometimes, I don't even see the BD icon in the system tray. Other times, I do, but the icon is grayed out, indicating the services are not running. Even after uninstalling and reinstalling BD, it might work for a while, only to be disappointed later. I've had BD for severa years now, only to see it degrade. Then there are the little functional issues, such as BD stating "The update has never been performed," yet when I click on "Update Now" or "Fix," it does nothing! Other times, it works. Recently, I got a trojan virus. Not to my surprise, it was because the BD services were not running! I can't have a system wherein the antivirus software might be unavailable. That's too much of a risk. I ended up having to uninstall Windows then reinstall it to get the virus out. Even after a clean install, BD still behaves abnormally.This has been going on since the last year, since v2008.
I'm done. Once my subscriptions ends, I'm looking for other software.
