Use a virus scanner on Linux to find and remove the windows virusses.
This sometimes works better than trying to remove Malwqare from a
windows machine that is running malware.

2 GB is great for Linux with VB. And VB installation is dead easy and
very well documented.
Now, say, you allow your XP inside Virtual-Box to use 768 MB, so it will
have 50% more memory than today. The remaining 1.25 (or so) GB will be
pretty ok for Linux, since this will be more than 2 times of what he has
This adds up to a very good user experience, assuming that he does not
do hardcor5e gaming and the like in Windows.
Moreover the benefit of never ever have to dual boot again, will buy
this idea easily.

No need to reinstall Kubuntu. Just save your mbr BEFORE you reinstall
windows. You can do it like this:
if=/dev/sda1 of=sda1_bootsector bs=512 count=1
Then reinstall Windows which will recklessly overwrite the MBR.
Finally save the then existing Windows-MBR (just to be safe) and play
back the original MBR, that you saved before installing Windows.
For the last two steps you will most probably a Boot CDRom.
Have some fun
