Hi,you do have internet access, if you are unnable to download the patch from MS and update definitions,which is a waste of time as the virus wont like that and further screw up your computer, trust me on this, been there done that!!
You need to get at a computer with internet access and click here, to get the patch from Norton, also go to the link for MS and get the security patch there.
These are small downloads and wont cost an arm and a leg on a dial up,even check out an internet cafe!!! have a nice coffee while doin it!!!
Load the security patch first, then load the Norton Blaster removal tool and let it do its thing..and that's it, oh yeah if you have Dydtem restore turn that off, first and restart it after you are rid of the virus.
You should be back in business, update your virus definitions, and then look at your second problem...
Hope this helps
Yours, a blaster survivor!!!!,
