virus help

for some reason....i cant browse sites except youtube and facebook on my firefox and IE and my other browser...."problem loading page" appears on all sites except those 2, my firewall is off, im not using proxy,....even my torrents connection.....all my torrent DL seeds and peers became 0.....i tried reformatting my PC but after extracting files from the CD(i even tried USB) it says cant read drive so i cant reformat my PC.....is there a way to know what type of virus blocks my net connection? i scan 2x adwares from my PC with NOD32 but it still wont let me connect

Try malware bytes and if that doesn't do it then restart into safe mode and insert the os cd and reformat to default settings which will just revert to what it first started with.. Have you tried system restore to a earier point like the last window update. If both fail. Hard format or nuke and boot... only if you have a os install disk though.

i scan my system using malwarebytes but didnt scan anything, i tried system restore too but i dont have a save system

Maybe someone put in a Net Nanny lol.
Too many porn sites?

the only porn site i visit is hongfire and fakku.....since i already reformatted my PC soo many times coz of random porn sites......but this is the worse i guess....since my PC wont read any of my drivers

Try this:

1) Reboot the computer but hold down F8. Highly Safe Mode and hit Enter. This will load only the basic kernel and drivers needed to run. Don't boot the Safe Mode with Networking.

2) Run the Malwarebytes again. Usually Malwarebytes is more effective in Safe Mode than in normal desktop mode.

Also, are you sure you are not limited by your ISP? Because some ISPs throttle your connection if you do exceed a limit.
