Trojan.Gen.2 & Trojan.Zeroaccess.B

Hi Everyone,

 

I hope someone will be able to help me with my problem.  Since yesterday I keep getting Trojan alerts from Nortan Anti-Virus every few minutes.  After running several scans I've been unable to remove the viruses with Nortan so I checked this Forum and discovered lots of all other people are having a similar problem with these two viruses and I'm hoping someone will be able to help me remove this (Sorry if this counts as a duplicate post, but I noticed that in the forum postings several people mentioned that the steps for removing these viruses varies from computer to computer so to be safe I decided to make a new post, if there's an existing solution for this problem please direct me to the correct entry).

 

my computer is running Windows 7 home premium, 64bp operating system

I have a flash drive
