I have never found the percentage scanned number to be very useful
For example I just did a Full System Scan and here are some numbers
20GB scanned in 3:05 and the percentage scanned is 0%
30GB scanned in 9:30 and the percentage scanned is 1%
40GB scanned in 13:12 and the percentage scanned is 6%
50GB scanned in 13:55 and the percentage scanned is 10%
60GB scanned in 16:30 and the percentage scanned is 12%
70GB scanned in 19:37 and the percentage scanned is 13%
Finished
261GB scanned in 25:20 and the percentage scanned is 100%
So the scan took
14 minutes to scan the first 50GB which showed 10% complete
11 minutes to scan the last 211GB and the remaining 90%
The Scan Percentage Complete, MB Scanned and Scan Time are meaningless when looked at while a scan is in progress if one is trying to figure out how long it will take a scan to complete.
The reason is some files take a long time to process/ scan that others… Its quite normal… Not only for scanning, for compression / extraction of files also it would be the same…
The image on the left says that it scanned 6 files. I guess it scanned the attached pictures/sound files separately. Not quite sure about it but there isnt anything unusual.
