BleepingComputer.com: Strange vimax ads, and weird internet issues

So, everything was going fine, then all of the sudden, about 85% of my adbanners on sites turn into vimax ads. Every now and then, i can be downloading stuff on bittorrent, and play a game called runescape which is a browser based java game, but i cant even search google, or anything. I have norton gaming edition antivirus, and the sonar started picking up on files with a series of numbers then .tmp and would sometimes detect a trojan. I ran full system scans all day, and every time, it wouldn't pick up anything. but all day long, sonar would be bugging me. My thought is either a virus is intercepting my ads, or someone is spending billions of dollars to get their ad noticed! it is even on my site (mods4wxsand.tk) i use google adsense, and i get the ads there, and the freewebs ad banner sometimes gets it! Runescape.com gets those ads all over the site, but it doesn't seem like something they would approve, since it is a game geared for teens, and this ad is for something like viagra... Its really annoying not only because i cant use the internet sometimes, but the ad is dumb, and i dont want to go to some sites with sensitive information in case there is a keylogger... norton updates like every 30 seconds, so i know i dont need an update, it is just really stupid. anyone know if this is a virus, and how i get the trojan thing to go away when only sonar can detect it? Other than giving specific information on how to fix it, pretty much all my questions can be answered if you fill out the poll.
