I've been at Daz reading about this in the Commons forum. Here's what Khai had to say...

OK

I've been hit as well. go here - http://download.drweb.com/drweb+cureit/ grab the Free program and run a scan. it will cure or quarintine the affected files.

no need to reformat / reinstall (unless you really want to, but trust me, you don't have to)

this ain't that bad. btw F-prot will detect it, Dr Web will cure it. other AV's checking atm, but AVG don't nail it (yet)

Khai also goes on to say:

tip
keep a floppy start disk with CDrom drivers
or have a Booting CD that will let you access your drives..

I have those handy in my kit. tho, soon I hope to make a USB version...

plus speaking from years of fixing this kinda thing, no. you did'nt have to format. infected or not, you can still disinfect a machine even if the explorer.exe is infected. trust me on that..

My idea of rebooting is kicking somebody in the butt twice!
