I had a lot of problems with Norton. Tried BullGuard and had better success. It updates an average of twice a day. You do have to pay to keep the system updating ($39/year), but it seems worth it to me - it has caught it's fair share of bugs coming through - but no anti-virus software is 100%, nor will they ever be. It is the mind of the virus creator against the computer and the brain will always win eventually.

Dear people,

The isle.exe is in fact the Bugbear virus. See this quote from virus info from McAfee:

"Installation

The worm copies itself to the START UP folder using a random file name (such as):

* Win98 : C:\WINDOWS\Start Menu\Programs\Startup\BSFS.EXE
* 2k Pro : C:\Documents and Settings\(username)\Start Menu\Programs\Startup\BSFS.EXE "

It uses a random file name. Sometimes this is isle.exe.

I helped my neighboors because the were suffering from a slow pc. So I took out their hard drive, and attached it in my computer running McAfee VirusScan Online. It had no trouble removing the bugbear virus (and several other virusses...). My neighbours used a really old Norton version with old scan engine. I'm going to suggest to them to buy a proper virus scanner.

Cheers
