My system has Windows 8 64 bit. I installed bitdefender windows 8 security trial version. But soon I came to know that its firewall component causes slowing down of internet. After further investigating I came to know that whenever I browsed a video streaming website like youtube internet speed get slow. The cause of this is that even if I closed the web browser bitdefender keeps downloading from these streaming websites.
Suppose if I watched 2 minutes of a video of total length 1 hr and closed the web browser. Then after closing the web browser bitdefender keeps downloading that 1 hour video in background.
This is total waste of internet bandwidth and causes slowing down when we browse other websites.
Both bitdefender internet security 2013 and bitdefender Windows 8 security 64 bit has this problem.
Other users also must be suffering from this problem. let me know if there is any solution.
