First up, How long has the problem been going on and what type of Internet/Broadband + speed do you have? And are you the only one (pc) on your lan or are other computers sharing it? If so, go turn them off before doing any of the below, and see if you still have the problem.
1. What is your task manager CPU percentage running at when you are loading pages or opening IE/Firefox?
2. Regardles, download SpyBot Search & Destroy. Install it, update the files, immunize and then run a scan and fix whatever it finds. Virus scanners don't find all adware, spyware and malware.
3. Do you have a router or modem? Are you on wired or wi-fi? If wi-fi, have you secured it with a passkey? You could be being jacked.
4. If you have a router, log into the admin page. One of the pages will display the upstream and downstream speeds that it is receiving. If these don't look like the speeds you signed up for then there's going to be a problem either in your router, noise/interference on the line to the exchange or there is a problem/work going on at the exchange. One way to clear interference is (as mentioned above) turn off your router and unplug it from your computer and the phone connection (very important part) leave this for 30 secs (or 2 minutes to be sure). Reconnect and restart after clearing your temp int files and running MS Disk Cleanup (don't check the Backup files option).
5. Are you running any P2P applications (Bittorrents, etc) or FTP servers. These will impact your speeds MASSIVELY if not configured correctly and will generally have a noticeable impact unless you have a broadband line with a 512kb/s upload or greater.
6. Should've put at the beginning but can't be bothered renumbering, make sure you've gone to the microsoft page to ensure you've got all the latest security updates (at the least). It's concerning that you say you've run several virus scans from Mcafee AND AVG... just asking, but you DO have one of them actually installed and up to date, right? You're not just running their web based scan are you? (Please don't shoot me for asking, I'm not trying to be faecetious. I work in IT and I'm constantly amazed how often this case can be found)
If none of the above help or point in the right direction, then grab a screenshot of your Taks Manager process window and post it here. Something might be apparent immediately. Else we move on to something like HijackThis.
Hope something in the above helps.
