in the shop i used to work in 95% of the puters that came in with probs had viri etc. you got it nortons.
what i did was slave the h/d off my shop puter with avg , adaware and most times fixed
I found an interesting thread
"For those of you who use Norton Antivirus I want to show you why I think it's terrible. I see this everyday and I decided to do an experiment the next time I had a "real messed up" computer. I have a clients pc with Norton 2004 installed that had not caught a single virus in real-time protection, the definitions were a few weeks out of date so I update them and set heuristics to the highest level. I then scanned the entire hard drive and let Norton fix/quarantine all the viruses it found. I then uninstalled Norton and installed AVG 6.0 FREE, updated it then set it up to scan all files and turned heuristics on. I then scanned the pc with Ad-aware, SpyBot and Spy Sweeper and used HijackThis to finish things off, here are the results:
Norton 2004: 188 items, some viruses and some spyware and deleted 73 items.
AVG 6.0: 13 viruses, repaired 11 of them and sent 2 to the virus vault.
Here is a list of the viruses it found that Norton did not:
Ad-aware: 68 items
SpyBot: 131 items
Spy Sweeper: 683 items
This is why I recommend people to uninstall Norton and install AVG 6.0 FREE, while there is no perfect antivirus program there is NO excuse for a FREE antivirus program to find 13 viruses over a product that you pay a lot of money. Norton is also "supposed" to detect spyware as well, you see how well it fared against the other spyware removal programs. Norton is a false sense of security, people post HijackThis logs all the time and said they have scanned for viruses with Norton and said their computer was clean, don't trust it.
I am not posting this to start an argument over what antivirus program is the best, I just want to justify why I recommend what I do. So Norton users please don't take this personally.
Every time I "bash" Norton here on this forum I'm asked to back up my reasoning, so here it is."
