Have you got anti-spyware? This is most likely your problem. Also do not give them admin accounts to use, they download junk and infect the machine. I use AVG for ALL my clients machines, it never lets us down. Do NOT run 2 anti-virus at once, they conflict and reduce security by about 60%.
Avast - free, or Avira - not free, but there is a free trial, and it gets high marks.

Rumor has it that running more than one AV at a time is not a good idea.
