Vista - removal of win32:trojan-gen. virus

I am using the free version of Avast AV and recently every time I boot up I
get a warning saying win32:trojan-gen {other} has been found. This happens
even tho' each time I have followed the recommended action and put it in the
chest. How do I get rid of it please?

through at least scanning with Multi_AV (see below). If Multi_AV thinks
the computer is clean, you can submit the suspect file to Virus Total
for identication and/or to Avast to see if this is a false-positive.

Include scanning with David Lipman's Multi_AV and follow instructions to
do all scans in Safe Mode. Please see the special Notes regarding using
Multi_AV in Vista.

When all else fails, run HijackThis and post your log in one of the
specialty forums listed at the first link above (not here, please).

Not all tools used will work in Vista and you will need to run them
elevated. Since Vista is so new, it will be a while before removal
techniques and tools are developed. If you are unable to remove the
infection by following the general steps, register at one of the
HijackThis forums as suggested.

Standard caveat: If the procedures look too complex - and there is no
shame in admitting this isn't your cup of tea - take the machine to a
professional computer repair shop (not your local version of
BigComputerStore/GeekSquad). Please be aware that not all local shops
are skilled at removing malware and even if they are, your computer may
be so infested that Windows will need to be clean-installed. Have all
your data backed up before you take the machine into a shop.
