"SCAN ALL FILE" FREZEE EXPLORER (AVPRO 5.0.677)

[GaAs]

Hi, VLK, Hi Avast Team.
Unfortunately there is a problem.
I set avast 5.0.677 as follows:
"Real-time shields"
1) scan when opening: i add "scan all file";
2) scan when writing: i add "scan all file";
3) used "transied caching" and "do not scan system dlls";
4) sensitivity: heuristic sensitivity high, use code emulation, scan for potentially unwanted programs.

Results: When I open a folder that contains many executables, explorer takes at least 15 seconds before access to files or the scroll bar can be used.
Sometimes it generates the total freezing of explorer processes which must be forcibly closed by the task manager.
Also reducing the level of heuristics or disabling the emulation code this happens.
I noticed that the problem occurs because of an "scan all files, regardless of other settings, and seems to be concerned avastsvc.exe which absorbs more than 60% -70% of CPU resources when the problem verification.
This setting affects performance so much?
If I can not use that option, what sense does it have?
Could you please check? Thank you.

Where you ticked scan all file's you are warned that this will have a negative impact on system performance,you should listen. I would suggest turning it back to default. These optional setting's are for extreme circumstances only and not for everyday use. And please don't post in multiple location's

With the options you set, there's certainly no wonder - and there's nothing we can do about it, avast! just conforms to what you asked for.
I suggest to use some reasonable File System Shield settings.
