Problem with my internet connecting...?

I have IE and also Mozilla Firefox. Forefox will not connect at all but internet explorer will but it take a long time to connect and to finish loading up. Everythings running slow. I cleaned up my disk and defragmented it. I have AVG AntiVirus free edition which does not fully protect my computer. But it does detect viruses and heals them. It detected one yesterday and asked if I wanted to heal it, so I did but it's still running slow and Mozilla Firefox still won't connect and IE is still going really slow. Should I do the system restore and take it back to an earlier time or should I un-install and re-install Firefox and or IE? If I was to re-install Firefox, how can I save all my bookmarks that I have saved under it? I don't know what to do... Any recommendations on what kind of security I can purchase online thats not too expensive and is really effective? Also anything that fixes disk errors,ect..

For the firefox bookmarks, go to organize bookmark. It will open a new window. The go to file -%26gt; export bookmark. It will then save the bookmark information to a Html file. Default name is bookmark.html. You can later then import the bookmark and find everything back to where it was.

For the firefox, I recommend you to install a addon call "no-scripts". It gave you the control of whether to load certain content from certain websites within a page you are visiting. It's not only blocks certain strange website and pop-up, it gave you a bit more security.
