I had a really weird first time experience with Bitdefender Internet Security last night.
I made a clean Windows 7 Ultimate x64 install. Then I installed Bitdefender Internet Security because I got a free trial of 30 days so it seemed like a good deal. Everything went fine. Then Bitdefender said I should install few more Windows updates to make sure I am secured. Ok, no problem.
After those updates Bitdefender said I still have one more threat to solve and that would be the password for my Windows account. As I said in the beginning, this was a clean install so I had only one account which was not yet password protected. Well, it was easy to set a new password through Bitdefender.
But the real problems started when I rebooted my computer to finish updates. I tried to log in but Windows kept tolding me I had a wrong password. WTF? I just set a new password like 45 seconds ago. There is no chance I would forget my password so quickly. I even used almost same password than in my previous Windows install (little bit stupid, but yeah) and I have never forgotten any password.
Of course there is a really small chance of a typing error but that is a really really small one because the same password had to be typed twice.
I am quite sure there is an issue with Bitdefender. I even found one old thread from the same issue.
I am so glad I solved the problem with Offline Windows Password & Registry Editor and got a chance to log in again. That tool saved me from a disaster!
I uploaded two pictures about my Bitdefender and Windows version.
