Does a format kill a virus?

  Totally-braindead 00:02 12 Mar 03

A friend of mine has had a virus on his computer, he has formatted the hard drive and reinstalled windows and his programs, but he still suspects the virus might still be there as the system from time to time does unexpected things. Now hes installed the latest version of Norton Antivius and updated it and it finds nothing. My query is this 1. can a virus survive reformatting the hard disk and 2. would Norton Antivirus definately find a virus if it was already on the computer before the antivirus was installed.

The format should have got rid of the virus unless it was in the master boot record (MBR), but if Norton says you're clean then you probably are.

As MAJ has said unless the virus was in the boot sector then it will be gone

a virus is only good if there is a pointer towards it, if there is no pointer(.exe) then there should not be a virus

you could run the "fdisk /mbr" command which will rewrite the mbr if he's not sure...

Memory resident ones need you to turn off pc for 30 secs at least to clear cach after format
or they can come back

"as the system from time to time does unexpected things" sounds like windows then.
