I got a worm not the sasser worm it closes the computer down no warning at all. I have done the scan for the sasser worm and came back clean. Avast hasn’t picked it up.
WORM SDBOT KY
system 32\ wumgrd.exe
What do I do?
Hi,
Info on the worm:

*** Please send in the worm file, if updated avast doesn’t pick it up when scanning in safeMode:
mail it to virus@avast.com , best in a password-protected zip-file; iclude zip-password and link to this tpic in the mailtext
look here for removal advice:

but please continue in this here posting 
P.S.: It’s wuamgrd.exe, right ?
And ooh yes, if the security of your system is dear to you, or you use onlinebanking/have sensitive data on it, you should redo your system from scratch, as it’s compromised
That worm is also known as Backdor.IRCBot.gen [KAV], W32/Sluter.worm [McAfee]
