can anyone help..?

Well, given that this is apparently a genuine question (albeit a prelude to a spam) there might be others interested in possible solutions?

1. As this is supposed to be a workplace scenario why not just blitz the drive with your approved corporate build? .............. you do have one of those don't you? ............. and there won't be any critical data on a workplace PC will there?

2. Use the Windows installation disk and do a fresh install. IIRC anything from Vista onwards overwrites the HDD first when you do that? Otherwise use something like D-Ban to wipe the drive with a single pass.

3. Remove the infected HDD and slave it to a "sheep dip" PC, then clean it from there. Personally I have USB caddies for this and other repair tasks

BTW a "sheep-dip" is what we call a stand-alone PC that is used for security type functions such as checking external media and cleaning malware. It is a good re-deployment of older or low powered machines as the bottleneck is usually the connection to the target. Probably the best way to go if you don't know what malware you are dealing with. You should always have a mirror of the sheep-dip's build.

EDIT:

The reason I prefer a PC to a live (bootable) CD is that it is much easier to keep the software up to date. On the other hand the live CD/DVD has the advantage of using an OS that the malware won't understand, and would normally not be writableto by malware.
