keyboard and mouse operations becoame slow after purchase of avast pro

[REDACTED]

I renewed to Avast Pro for 2 years after expiry of Avast Internet Security. But since then I am facing performance issues. When I am typing it is appearing with delay and often closing of browser tab or window also responding late. Moving mouse also performing with delay.
I don't know why it happening after avast, as avast gave free look period, I would like to cancel order and get back my money.

Please respond to my query,

Thanks,
Regards,
Krishna

What shows you that it is avast that is causing it ?
It can be something else.

Why not try to solve the problem ?
Perform a repair of avast and see if it is solved.
If not, perform a clean installation of avast and check again.
