F-Secure Safe skipping big amount of files in Full Scan
I'm using F-Secure Safe for 2,5 week now, but I'm ecountering a problem now for a few days. I've contacted F-Secure customer support, but they couldn't find anything, so my last chance is trying it here. I'm running it on Windows 7 professional SP 1. (I've don't got any error logs, since there aren't and also the full scan report doesn't shows any irregularity)
I've did a full clean install of my PC 2,5 weeks ago and I'm using F-Secure SAFE ever since. For the first 2 weeks, when doing a full scan (with "scan only known file types" unticked and "scan compressed files" and "scan with heuristics" ticked), it scanned about 220.000/230.000 files consistantly for the last 2 weeks.
Without any change to my PC (not installing or removing anything), it suddenly only scanned around 130-140.000 files when doing a full scan, a few days ago. So suddenly it scans 80.000/90.000 files less! The whole point for me is that, when doing a full scan, it scans everything and I can feel pretty sure that my PC is clean. When skipping this big amount of files, I don't trust it to be clean.
At the same time, Malwarebytes (which I use as second scanner) kept scanning the same amount of files in that period.
Ive tried a complete removal and reinstall of F-Secure, but that didn't change a thing. Tried to scan with all the options and combinations ticked or unticked in the settings menu, but it also didn't solve the problem.
The only thing F-Secure support could think of is that I removed my temp files or that a program did. I haven't got a cleaning tool on my PC, so that isn't the case. The only thing I did was removing cookies and temporary internet and website files manually in the Internet Explorer settings menu. But could that make a difference of 80.000+ files in the full scan? (And why isn't there a change in the amount of files Malwarebytes scans then?)
Anyone got any suggestions?!?
