Slow and freezing writing when I have anti-virus enabled

Hey guys,

I noticed that when I have total security activated, in some moments (I haven't noticed a pattern yet) when I'm going to write, the writing of the characters hangs. Usually I click on a field to write something, I start typing and it is stuck, the letters do not appear, after a few seconds what I wrote appears.

I did the test with the antivirus on and off, this only happens when it is on. I currently use the browsed microsoft edge Version 85.0.564.63 (Official build) (64 bits)

How do I solve this problem?

@Thiago Borja Welcome.

Please contact Kaspersky Lab Technical Support https://center.kaspersky.com 


I also have total security installed, and I noticed that the speed of  internet download is very slow. 

The speed only gets better soon after the computer has inicialized. 

Some tip to solve this problem?
