Many times during my hours of navigation I end up redirected to a random site. For example, I got to Legendaryfrog's site and I'm redirected to google, and the problem keep on annoying me for a while then it stops. Also I sometimes end up being told that I am not allowed to go to some site while 5 minutes later I can visit this same site. And at very rare occasion it just shows random characters instead of showing the page I'm visiting. This is very very annoying. It's not an spyware or anything because I recently scanned my PC with adaware. Oh and also sometimes there are pop-ups showing while my Pop-up blocker is on, and these pop-ups are always the same pop-ups.

Run ADAware (updated) in Custom mode and select all of the options you can. This will do a full scan and pick up some programs like KeenValue that the normal fast scan does not pickup. AdAware neglects to tell you to do this the first time you run it and after major updates, unless of course you complain about it not finding everything. Then they will insist that you should have known to do this Custom mode scan first. I just leave mine setup for the full Custom (longer) scan. Then try SpyBot_S&D as it may pick up other spyware. Also OPEN and run CWshredder.exe to check for the very latest browser hijackers.
