Severe Keyboard/Mouse Delay/Lag in IE, Edge & Chrome ONLY

I'm at my wits edge on the issue I'm having with my mouse/keyboard (Logitech K350). I waited till the last moment to install Windows 10 Pro before I couldn't obtain it for free. I created a ISO of Windows 10 (received from MS). Did a fresh format on my system, reinstalled my Windows 7 Ultimate, completed all updates & driver installs, then proceeded to upgrade to Windows 10.

After the install of Windows 10 Pro, drivers/updates, installed Office, Chrome, Adblocker Plus, etc. everything seemed to be fine. I had Avast! installed on my system. I work from home and my job demanded that I had to use their antivirus program. So I uninstalled Avast! & installed Kaspersky EndPoint Security 10 for Windows 10.2.4.674 (I believe it's custom build for the company).

To the best of my knowledge I believe this started after the install of Kaspersky. It prompted me of my Logitech mouse/keyboard BadUSB and wanted me to type in the access code (see example image below)


I can be typing in any browser (Chrome &/or Edge) or doing my data entry in my work browser (IE) then suddenly my typing stops even though physically I'm still typing. Then after about 10 - 15 seconds, suddenly everything appears 1 char at a time (fast). I can hover over a button/link, then click it, and it will do nothing then about 10 - 15 seconds later it's like I just clicked the button/link.

This delay/lag issues is extremely annoying, especially since my job is very fast pace/high volume of typing, plus it delays unnecessary time with customers on the phone. Any suggestions or help would be greatly appreciated before I wipe my system and revert back to Windows 7 :/

Found this post at the Kapersky site (dated 12/18/2015):

https://forum.kaspersky.com/lofivers...p/t340802.html

A very long read with no solution offered (as far as I can tell).

If no one here offers a solution, I would definitely report this to your company's IT department and also try Kapersky support as well.

Good luck,

Thanks I'll read it over and maybe post on their support forum too ... I have reported it to my company's IT/tech department; but they are assuring me it's not the antivirus.

Sounds good and send your IT guy a link to the post I provided so they know it is not you. Good luck!

See here: Kaspersky Endpoint Security 10 for Windows: Service Pack 1 Maintenance Release 2 (version 10.2.4.674)

Excerpted from above link:

A new component named BadUSB Attack Prevention has been added.
BadUSB Attack Prevention allows you to prevent your computer from connection with reprogrammed USB devices that emulate keyboards. When a USB device is connected to the computer and identified as a keyboard by the operating system, the component prompts the user to authorize the newly connected device. Any keyboard that has not passed authorization will be blocked.

I added that, and it still does it. I put the same post on the Kaspersky forums hoping for some type of suggestions from them. I'll change my batteries to be on the safe side. I have even uninstalled the USB controller, the keyboard mouse from device mgr etc. same thing.
