Spyware, Virus Removal Question

I have multiple viruses on my computer. I am currently going through the steps in the "DO NOT POST UNTIL YOU HAVE READ THIS: How to: Spyware, Trojan And Virus Removal" http://forums.majorgeeks.com/showthread.php?t=35175&goto=nextoldest

I have a few questions- In the following step, what do I do with the information I receive after doing the Symantec Security Check. It just lets me know I have all these viruses, but doesn't get rid of them.

b) And Windows XP, 2000, NT, ME, users boot in "safe mode with networking support" (and remain in there). See how to boot in safe mode below.
do an online scan at Trend Micro's Free Online Virus Scan
do an online scan at Symantec Security Check
run McAfee AVERT Stinger

Also, I am not able to get any updates from Symantec during the security check. I haven't been able to get updates for some time. Is that a problem in going through these steps?
Thank you.
