Hi,
I have been battling with a problem for a week or so and have now discovered that Avast appears to be causing the following issue.
I have a new (less than 2 weeks) Lenovo T440s i7 12GB RAM with 512 SSD drive running windows 8.1 which is no slouch.
However, after booting the machine all is well. Until I open a folder by right clicking my computer and opening any drive.
After doing this the desktop will not allow me to highlight any folders or use a context menu for around 10-15 seconds, after which time everything returns to normal and the problem will not re-occur until reboot.
The reason I have just begun to suspect Avast is that when checking IO in task manager I noticed Avast taking the largest amount of IO upon opening the folder. So as a test I have tried booting the machine and disabling all shields before opening the folder, with Avast disabled no delay occurs.
Fast boot is enabled but for a while I was running with it turned off and I am pretty sure the issue was still present then.
Hopefully someone can guide me as to what settings need changing or whether it is a bug that will resolved.
Regards
Baz
