I read that some versions of Kaspersky are not compatible with it. I suspended Kaspersky’s protection, launched Malwarebytres, scanned, I had a lot of dangerous files and programs - more than 500, and he quarantined them all ... Then I turned on Kaspersky and he immediately deleted Malwarebytres.
It would be nice to clean everything that is not needed from startup
And after that, it's not bad to clean up the Windows registry ..
And the computer will work faster
Which Kaspersky is it for you?
In my (possibly erroneous) opinion
all products except Kaspersky Antivirus are redundant and solve issues that are not characteristic of the antivirus. Therefore, I use KAV
To use a firewall (if you are using a computer running Windows) I recommend using a standard Windows firewall with this add-on
Sphinx firewall control
You can use the free version, but ideally the Plus version
