After install "Bitdefender Total Security 2012" web browsing speed slow but if i download files by using download manager then i can get my full download speed. Then i uninstall Bitdefender then my web browsing speed again OK. So this is not a ISP issue its Bitdefender Issue. Most of the time Google chrome display "Error 101 (net::ERR_CONNECTION_RESET): Unknown error."
So how do i fix this issue?
