I am getting an incomplete software scan on 2 of my pc's. Under software report for these two pc's there is only 8 items listed. Consequently, they show up on the "All workstations without Anti-virus software" report, but they have the same anti-virus software the rest of my pc's have. I can find nothing that is specific to these 2 computers that might cause this. It appears to be a random problem. Any ideas?
