I have a 30 MBPS down / 3 MBPS up Fiber Optic Connection
I have been getting a lot of slow downs for the past 6 months in my internet. Not downloading, only browsing websites. When I enter the URL , before I actually start seeing the page start to load there isl ike a 3 to 5 second delay as if the browser was busy doing something then it would start to load the page.
I tried many tweaks and formatted my laptop many times to solve the issue but no luck.
It seems it was Bitdefender Antivirus 2013 causing this because when I installed Eset's NOD32 Antivirus this time, my browsing became very fast and snappy!
I am running Windows 7 Professional 64-Bit SP1 with the latest updates and freshly formatted system and the built in Windows Firewall.
For now I have stopped using my 5 year Bitdefender license until a major upgrade happens to fix this. I am very disappointed and wish I didn't buy so many years of my license valid for 5 PCs
