I have read some references to a lot of disk activity after wakeup. I am on 5.1.889, and on boot up, I am now getting a huge amount of disk i/o, over 250,000 read i/os caused by AvastSVC. This has, I think, only started following a recent engine update a couple of weeks ago. It seems that it is now doing a major scan on startup.
Is there an explanation for this?
Hello Daviddv,
Maybe it is rootkit scan on system startup.
You can turn it off from avast settings, though I don’t recommend to do this (this lowers security level).
- Open avast window.
- Click “Settings” on the upper right.
- Open “Troubleshooting” and uncheck “Enable rootkit scan on system startup”
- Click OK to exit.
If this does not solve your problem, I would recommend reinstalling avast.
Rootkit scanning? I don’t think so… it runs only 8 minutes after boot, not at all wakeup.
Is there any scheduled scanning?
I always thought that a scan for rootkit was quite quick involving only a few files etc. I don’t want to disable this feature, so I will follow your suggestion and try a reinstall.
Thanks for your advice.
It might be already too late to say this, but I would suggest using avast! Uninstall utility to clean up remnants of avast after uninstall.

Before or after reinstall, I would also suggest to follow Tech’s advice.
There is a possibility of being scheduled some scans by accident.
You can still use Process Monitor tool (http://technet.microsoft.com/en-us/sysinternals/bb896645), it shows you current I/O activity in whole system.
