I updated to BD TS 2013 (from BD TS 2012) when it was first released. I've set it to auto-update and completed every update. I've had nothing but problems with 2013 since the day I first installed it. Problems ranging from missing and totally absent panels, critical errors causing 2013 to completely shut down and events which cannot be cleared. I've opened many tickets with "technical support" (sic) and followed their instructions to the tee. Each supposed fix created more and different problems. I even notice that BD has taken away their technical support chat function. I suspect this is due to the plethora of problems with 2013. I've uninstalled 2013 and gone back to 2012 but now I keep getting this nagging screen wanting me to update to the malware 2013 version. I will not recommend BD TS 2013 to anyone. In fact I intend to spread the word about this bloated piece of malware called BitDefender Total Security 2013.
If you ban me for expressing my true feelings and experiences then so be it. At least have the integrity and courtesy to refund my full purchase price.
