Really BAD virus, help

Hi,a dood at work had this virus on his pc,when ever he copies any file from an external device the virus kicks in and atomaticly copies everything on the external over to your local drive without you knowing,and when you open mycomputer your entire drive is suddenly full,all files are copied severall times and all the files even files that are gigabytes in size showe next to it 99kb.The virus is known as something with "rotinom",the worst part is he tried every antivirus and none of them pick it up or remove it.Can anyone that knows something about this rotinom crap please reply on what to do!

Naw,we thought of that but it efects any external,even flash drives

Well Mitchell 65,i thought it to be logical because its a windows 7 forum,people would assume the operating system was windows 7,more precise ultimate 64 bit.As for the anti viruses we used Norton,avg,Mc-afee,avast and viper.

Thanx Dinesh,ill try it

To Any that read this thanx for all the replies,JACEE,i did as you said and sovar it seems the virus is gone,the bad thing is it was quarantined by the latest Avast,and those file were then picked up with Viper(viper was suggested by threat-expert)In the end Viper removed all infected files,which then cleaned out the external completely,after a external format,it clean.So if you get a virus that copies everything you have on your local drive use Viper,the link is supplied by one of the guys earlier in the thread,it worked....at a price
