Avast constant writes to SSD (lscache.dat)

[REDACTED]

Hi Guys,

I've just noticed that my AVAST Free is constantly writing to a file called "lscache.dat" located at "C:\ProgramData\AVAST Software\Avast". And the only component that is active is the "File Shield". The problem is not that AVAST is writing something, but that it writes constantly with a speed of 130KB/s. And a simple calculation reveals that: 130KB * 60s * 60 min * 12 h = 5,616,000KB ≈ 5.3GB writes per day.

I believe the primary purpose of an anti-virus program is to scan your hard drive, not to write to your hard drive.

Any comments on that?

That's not normal. At my computer this file has 3 kB and doesn't change...

Yes, it's not normal!
Even my browser with 100 tabs open is not writing to the hard disk at such rate!
The problem is AVAST writes with 130KB/s every single second, continuously! I would understand if it needed to update "lscache.dat" file every minute, or every 2 minutes, but constant writes is not acceptable.

P.S. Never mind, I've just uninstalled AVAST.

I have tried uninstalling Avast, reinstalling, still problem, uninstalled Avast again and updated Win10 several versions, reinstalled newest Avast version hoping it would work normally.
All in vain, after a few hours of reinstalling Avast, it starts up again(Prob starts at once, but takes a little while till its noticable) and brings my HDD to 100% activity and file grows to insane size after a couple of weeks if I let it.

I have loved Avast and used it for many years, also have many other PCs running it flawlessly. But on this PC it looks like I will have to find another permanent solution.

The troubled version I have used now is "AVAST INTERNET SECURITY" version, but also think I saw the same in the avast free version.

Really sad since i am saticfied with the functionality of Avast, but I cant have a bug in the software hog my system resources and possibly destroying my HDD at some point because of it.

So I really hope Avast can find a solution to this odd behaviour at some point.

(Note: When I do not use Avast, but alternative security software, there is no problem!)

Where are you getting the data from to show Avast writes constantly with a speed of 130KB/s.on the SSD?
