I'm not sure what you mean by saying your Sophos av files haven't been
updated "as no longer in contact with person who installed". Having
outdated virus definitions is almost worse than having no av installed
at all. If you are unable to update Sophos, uninstall it and get a
full-featured av immediately. If the virus is running on startup, it is
*not* contained only in System Restore points. The virus files in the
System Restore points aren't active; something else on your hard drive
is.

Delete all Temporary and Temporary Internet Files. Then scan in Safe
Mode with TrendMicro's Sysclean:

TrendMicro's Sysclean is an extensive antivirus tool which has the
advantage of not needing to be installed. It requires two parts - the
scanning engine and the virus pattern files.

1. Create a new folder on your Desktop or the C: drive named something
useful like "Sysclean".
2. Go here and download the two parts of the program to that folder:

http://www.trendmicro.com/download/dcs.asp - Sysclean
http://www.trendmicro.com/download/pattern.asp - virus pattern files

The pattern files will be zipped - extract them with your unzipper (like
WinZip) or if you have XP, you can just open the folder. You need to
put the extracted files in the Sysclean folder you made.

3. Restart your computer in Safe Mode. Get into Safe Mode by repeatedly
tapping the F8 key as the computer is starting up to get to the proper
menu.
4. Go to the Sysclean folder you made and double-click on sysclean.com.
Start the scan. After the scan is finished, look at the log. You may
need to make a note of where any viruses were found if they were not
able to be removed so you can manually delete them.

After you've scanned with Sysclean, get and install the full-featured av
(uninstall Sophos first), update it, and do a thorough scan in Safe
Mode. After you've done your virus scanning, remove non-viral malware
with Ad-aware and Spybot Search & Destroy. Make sure you update those
programs before you run them, and do your scans in Safe Mode.

After you know your computer is 100% clean, you can make a new System
Restore point and then delete all the previous ones by using Disk
Cleanup's More Options feature.
