Anyway... free antivirus, not too heavy, effective... I'd suggest
AntiVir if it were me. If your SAS software will function in a
Limited user account, that's also a major security upgrade. If you have XP Professional or XP MCE, you can also add a
Software Restriction Policy.
If the program has problems when it's run in a Limited account, then LMK and I could suggest a modified plan. If so, mention which version of WinXP you use (Home, Pro, MCE). Make sure the software installs to a location within C:\Program Files and not directly in the root of C: or something dumb like that.
