when doing rootkit scans the scan starts fine and seems to progress fine, slowly the progress moves up e.g. 3%@15mins, 4%@20mins etc the higest I've seen it was 10% after about 50mins of scanning (note these are not exact figures).
I leave it thinking it'll take ages to finish.
Then when I return it's suddenly finished!! However I have always returned after a short time e.g. 15mins when I would have thought it may have progressed a few more %.
Is this sudden finishing (I don't know if it suddenly shoots along showing 90% progress etc) normal behaviour? or is it an indication I may have some problem?
I have the latest version of ZAISS with auto daily updates set, running Vista (also updates automatically) on an Acer Aspire 9420 (about 2yrs old).
