NAV caught this little bugger on my system last night, after a week or so of weird stuff happening i finally figured out why
This little pest appears to have used up around 40 gig of space across 4 partitions one a 120 GB HDD. I have no idea how i got this worn, or how long it was resident on the drives for but i can only presume it was there for at least a week. The first thing that happened was NAV died a horrid death, then a critical error sound popped up between every 4 and 6 minutes and lastly i seemed to be losing HDD space faster than i could fill it (40GB in a week on 512 ADSL would be hard going!).
What to look out for: A recurring windows Critical Error sound
NAV Dieing a nasty death ( Unable to run program, scheduled scans won't run, Unable to close NAV when trying to restart etc)
Sudden unexplainable HDD space usage
The creation and replication of a file called "Explorer.exe" approx 400kb in size
The Symantec web site has very little on this worn, apart from to say its rare. How nice for those of us that have our computers infected with it.
The latest NAV AntiVirus definitions catch and repair the damage caused by this worm, if NAV works for long enough!
