Hi jd_1960, Is this an XP machine?
If so you can run this first in normal mode.Windows OneCare Live
Be sure to click ONLY on the grey box below the picture of a wrench “Full Service Scan”
This may take some time ( hours)especially it it needs to defragment the drive.
Then I'd run the antivirus that is on their machine in Safe modeHow to start Windows in Safe Mode
If they don't have AV use these
Install AVG Antispyware, then run in SAFE MODE.
This may take quite some time, an hour or so, depending on speed and infection
First go here and print out these instructions
on install / scan with AVG
Be sure to check for the any updates to the programs after you install these.
