My PC has a virus and is sending 100 of my email.How mens proxy can I fix this myself? Please help!

Norton said first that there were 4 viruses detected … one that can not be accessed or deleted. This was 2 days ago. Now in the bottom toolbar there are tons of envelopes with a magnificent glass in it. Symantic is running an analysis on all these msgs. And are endless! I keep getting hundreds of pop-ups from Symantec (Norton) saying that the msg I sent was denied, SPAM, permanently blocked, or I need to try again later. Of course I'm not going to send messages, and now is running EXTREMELY slow and I'm still getting the popups. I called a computer-binding site, said I can try to make a backup of data which could solve the problem. If I do not have by a technician to fix it for about $ 120-150! PLEASE HELP ME! I would do this to my car. I'm fine on the computer, I have never found a company issue. I do not have the $ $ to bring it in. If anyone has any advice or some things that I can try it deeply grateful! Thanks

Try this ………. Download the free version of AVG. – Turn off your Windows restore feature. – Shut your computer and then back on in safe mode. I think you can do this by pressing F10 as the computer is booting up. Run a full system scan with AVG and must remove it. Hope this helps
