com.avast.daemon using 65 % cpu
kernel_task using 41 % cpu

(hmmm, more than 100%?)

Because you have more than one core, 200% = using 2 cores at full capacity, 400% = 4 cores, etc.

Same problem, as Avast is eating up my cpu.  Also, the scanning stops without completing a full scan.  It pauses at a certain file, and never moves past it, all the while the clock keeps running.

I just turned off the 'File System Shield' and restarted my computer - Voila! My system is now using 3%.  A drop from 96%.  Unless Avast can fix this problem, I will be going to another anti-virus program.  Also, Avast is still not running proper scans (it pauses on certain files and does not start up again, though the clock keeps running).

There was a serious bug that caused the scan engine to deadlock
on some special files in 10.6. Version 10.7 (43713) fixed this.

Now that we know which version of the program fixes the bug, do we know which program version numbers were affected by this bug?

Affected versions are 10.5 (beta) and 10.6.

From our experience, the bug does not seem to affect OS X 10.10 Yosemite, only Mavericks and earlier.

It affects Avast on any OS X version. In your "test set" you most probably do not have 10.10 machines with
files triggering the bug.

That is completely plausible since we don't have Yosemite widely deployed yet, maybe 10 clients out of 4,000.

I'm running OSX 10.9.5 and Avast 10.9 and am having the same issue when changing folders via Finder. Every folder change spikes com.avast.daemon process to around 100%. I'll send a test support package.

Avast should seriously consider adding an option, to do file scans only when plugged in to power supply.
I don't mind avast crunching through eating up extra CPU, but when unplugged, it's draining my battery like crazy. When avast file scan is active, although it does not eat 100-400% of cpu like others report (only aroung 30-50%), but my battery gets drained with in  2-3 hours, when avast file scan is off, i can get solid 6-8 hours out of my battery.

That's a perplexing proposal, what's the point of having an AV if it's not scanning?
