Removing malware by remote
1). Remote access by you using a live CD and with this connecting to your friends computer and then you removing the malware ?.
To do it this you would require a live CD OS (Ubuntu,etc) or a rescue CD that has a browser that can get internet access and has anti-malware software installed to it. You could from your computer, using the live CD, use your friends system to connect to MSE or any anti-malware site.
2). Remote access by you giving advice and they burn, insert and use the live CD?
This has a list of live CD anti-malware options and this is from the 'Live CD list'.
I have used Kaspersky resuce cd and have read/ heard good things about Panda and AVG.
I have not needed to use any, but would try Open diagnostics from the 'live cd list- windows antivirus'
This may not sound like good advice but i would go with any Free CD first and see if it removes anything and then possibly look at a 'try before you buy' and so on.
If you do not have a cd burner Imgburn is a good selection and the guides tell you all you need to know when burning an ISO.
Other remote as in advice.
3). With internet access.( i would try this first ).
Using this option your friend could connect to MSE and use/ install the free service and remove the malware that way.
4). The last but possibly the best is to Re-install the OS.
a). First run a full backup (the malware will be backed up and this is as a 'just in case)
b). Copy all data to CD/DVD (documents, music, video, etc )
c). Re-format, re-install and update - this wipes the drive and takes it back to a clean OS.
d). Install the anti-malware of your choice, update it.
e). Reinstall all programs( from the programs wesites) and copy the data off the CD/DVD back to the OS.
The malware should get picked up by your new anti-malware system.
If your friend does not have a install CD you can use any XP install disk and use the product code from your friends computer
( this is legal - or so i have been told ).
Sorry if this is a bit wordy.
Hope one of these solves your friends problems.
