To anyone out there considering purchasing product from BitDefender, I'm assuming people will check out product forums prior to purchase.
Be aware of the fact that Bitdefender use Avangate for payment. I purchased BitDefender 2010 a year ago. I'm 95% certain I did not agree to an automatic renewal. A few days ago I received an e-mail from Avangate saying that I placed an order on the BitDefender site but there was an issue with my credit card. In fact the 'order' was an automatic renewal - placed a couple of weeks early I might add - and the renewal had failed as my previous credit card had expired and my updated card has a different expiry date. I eventually spoke to someone at Bitdefender who assured me that I would have received several e-mails reminding me that my renewal was due and would be done automatically. No such e-mails have arrived and I am 100% certain of this. So the net result is that if it had not been for the fact that my credit card details had changed I would have been charged for a renewal. As far as I am concerned taking money from a person's credit card without their express permission is theft. A quick check on Google for Avangate shows a number of other people who have 'issues' with this organisation. As it is I have no intention of renewing my licence for BitDefender AntiVirus. The product seems to be good but a previous experience with their woeful technical support has made me decide to look elsewhere.
Hope this helps others make an informed decision.
