There might be chances that your windows build does not support kespersky or you need to download and install the latest version.
After reinstalling the software, if the problem persists then try to run the program compatibility troubleshooter
under the additional troubleshooter in Windows settings. You can find it by the following -
Press Win key
and type settings (or click on gear icon)->Update& Security-> Troubleshoot -> additional troubleshooter -> program compatibilty troubleshooter
- Now click on run the troubleshooter and it will detect your all installed program.
- now select the Kaspersky
and click on the Next button
- Now click on troubleshoot program and select the problem what you're facing, if it's not listed there then select "I don't see my issue listed here"
- It will give you the option to test the program
and click on the Next button.
in the end save your settings, if your issue has been fixed if it still persists then you need to contact its customer support.
BTW, here I recommend you to use windows defender as Microsoft has upgraded its feature that's far better than Kespersky and free to use. Or if you still want to use any premium antivirus then I would suggest systweak antivirus. Its price is very cheap and features are awesome as compared to other antivirus software.
Also, On September 13, 2017, the US Department of Homeland Security banned the use of Kaspersky products by all government agencies in response to allegations that Kaspersky had collaborated with the Russian Federal Security Service (FSB) to use Kaspersky software as a tool for facilitating espionage and the theft of sensitive data. Kaspersky has denied these allegations.
