I just got a new PC that came with Windows XP, this is the first time I have ever used Windows XP. About 2 1/2 minutes into my first connection with my new PC, I got the blaster worm virus. Norton first tells me that I have the virus, then it tells me I cant get rid of it, then it tells me to download a Norton tool to remove the virus, THEN, when that tool scans my system, it tells me i DONT have the virus. then i look in my virus log reports and see about 1000 attempts to delete and/or access the virus within about 1 hour. I realize that there are probbaly 1000 solutions and threads for this problem, but I always just start my own new thread when I have a problem, even the most common ones. I try searching for threads containing the words "blaster worm" but i get a lot of stuff that has nothing to do with what i am trying to do. i just dont want my new pc to be infected anymore and was hoping someone here knows EXACTLY which simple steps i need to take to rid mysef of this. thank you

norton says that

We recommend that you block access to TCP port 4444 at the firewall level, and then block the following ports, if you do not use the following applications:

TCP Port 135, "DCOM RPC"
UDP Port 69, "TFTP"

i probably should find out how to do this also or what it even means anyhow... does this mean i should download zone alarm - - also how much better is zone alarm pro than just the freeware version of it?

Additional Information:

BTW, how did you manage to get it in less than 3 minutes? If you do not have a firewall, I'd get one now. You can get a great free one at Zone Alarm

The Pro version of ZoneAlarm adds several features. Comparison chart. But the free version is a great basic firewall.

Hope this helps.

The only way I know how is if you have Norton AntiVirus and you go to the Symantec site and there will be a link to a tool that you can download called FixBlast, I deleted it awhile back, but it should still be there. I actually dont know for sure if you need to have a Norton subscription to download it...
