I used to have 2011, which I had no problems with it. I get a new computer and when the moth free virus ran out. I installed bit defender 2012 and have had nothing but problems.
1. I cant use Chrome, it just says loading page and eventually times out. Other browsers are fine
2. I have also just found it that it causes Dragon naturally speaking 11 to have an error on start up. I only work this out after spending 4 hours trying to get it to work today and as a final option tried switching off bitdefender.
3. I am sick of having to chase the support people for answers, I reported problem 1 on the 22/09/11.
If I swich off bitdefender both the problems disapear.
