After updated to 6.0.1367 mouse click /on a desktop icon/task bar icon/to close a window/refresh/almost all mouse clicking shows some hesitation to act.I need to click 2,3,4 and sometimes more times to perform an operation. Before update there was not such a problem. Is it due to some bug…???

Try a repair of avast followed by a reboot, test and report back.
Repaired and Rebooted…now I can’t feel that problem, I think it has gone…

Your welcome 
it’s amazing what just a simple repair and reboot will fix, sometimes just a reboot does the job.
Oh…sad…the problem came back after yesterdays startup… Clicking…clicking…clicking…??
