Will this tactic work?
If I transfer all my harddrive to a memory stick (the size is 4 Gigabytes) can I then plug it into a PC with Norton installed and scan it that way?
I ask because I cannot scan my pc at the moment because a virus(or a trojan or I know not what) is effectively blocking my internet access .
Again would Norton Antivirus be up to the task as someone (my ISP) said they thought it might be a trojan to be redirecting my outgoing traffic in the way that it is.

hi geordief

it might take a while depending on the size of your hard drive but this should work also try spybot search and destroy in google that should also be able to help.
Regards,

John

thanks
could there be any chance at all of infecting the (brand new) computer with the stick ?- I am virtually certain it has something very bad in it.
The computer I am contemplating using is , as I say, new and has Norton 360 installed .That makes me feel reassured but could there be any chance at all of infecting the computer with the memory stick provided I don't actually open anything (on the stick) and all I do is to subject it (the memory stick) to a scan?

Yes. There is a chance that the infected stick\flash drive could infect the new PC.

MS just recently released an update that disables auto-run on all devices except optical drives. If your new PC is fully updated\patched then it should minimize the cross infection risk.

Auto-run was\is a primary infection entry point when it comes to flash drives, media cards, external hard drives.

You could just download an on demand virus scanner such as Dr Web CureIt onto the memory stick and transfer it over to the infected computer's desktop and run it from there

It could work, but there are also risks associated, you could infect the other PC.

I recommend you use a Live CD to scan your computer. There are a couple of free Live CDs available, like F-Secure Rescue CD.
http://www.f-secure.com/en_EMEA-Labs/security-threats/tools/rescue-cd/
Download the rescue CD, burn the ISO image to a CD, boot from the CD on the infected computer, and follow the instructions.

If you want to see how it looks before you download & burn the CD, I've made a YouTube video:
