I need big time computer help! Viruses! Its a work computer...?

Okay. This is all a recent problem. I recenly intalled Windows Service Pack 2. I don't know if it is related but ever sense then I have had nothing but problems. I have norton anti-virus on my computer, and I have ran some scans and it just says that two non-viral threats remain. However when ever I opened internet explorer Norton would send me several messages stating I have viruses such as, Trojan Vundo, Trojan Horse, and Trojan. Low Zones. I have also been experiecing pop ups and new whole ad pages pop ups. The regular pop ups are suggesting that I scan my computer with Win Anti Virus Pro 2007. I will also get a page that will pop up taking me to either some advertisement or to the Win Anti Virus Pro 2007.

My computer has been running terribly slow. Please help. What can I do? This is a work computer so it cannot be infected!!! Norton scans say I have two non viral threats, but then why do they warn me about viruses on my computer? The norton pop up states they cannot be repaired.

No. Keep SP2. Try and follow these steps to kill off the malware.

Firstly update and run your anti-virus product. You can also run a free online scan as well as some malware can actually corrupt or disable your resident security products. Here are a few online scans you can run:
