No issue here, but looking at your image it doesn't look like the avast File System Shield has scanned many files (considering the number of web shield scans to be able to place a number in the bar chart.
Have you tweaked the file system shield settings as your number seem very low ?
Compared to mine and I haven't been booted and browsing very long.
Your Mail Shield is equally small in the bar chart (like mine) and that doesn't show numbers. But if like me you don't receive many emails off-line (my anti-spam filters lots), then you wouldn't be getting many scanned.
