Hello,
I noticed a problem after i installed Bitdefender Total Security 2013. When i try to update or create a file with some FTP program (like PSPad, FileZilla, Aptana 3 Studio etc.) the Bitdefender firewall is blocking something. I created some rules, I have added those programs to trusted list so they are allowed for everything but it's still not working.
Also i can't explore network not in my IP range (my bitdefender have ip in 192.168.1.X and i can't explore files on computer in 192.168.0.X network - of course with Bitdefender Firewall Off everything's fine)
