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
