I'm not sure which level of kaspersky you are using?
If you look on the comparison chart on that link , the anti-virus has less check marks for some of the things while the internet security covers them..
If you are using the base version , I'd upgrade to the next higher level to see if it works better for you..

I tested the top 5 about 6 yrs ago, and I just liked the Zone Alarm Extreme the best, the way it was set up, and it didn't bog down the system, but we haven't needed it the last 2 yrs so I can't say how it performs now...., and we used it on multiple pcs for 4 yrs.. returning customers will get or can request discount on renewals..

But since Windows XP got" retired", I went with Linux Mint Mate and don't miss Microsoft Windows a bit..and no AV needed...
Mint Mate comes with WINE and I can still use most windows programs by opening the program using the WINE program...

Best part yet it's all freee...


**************You can have more than one AV program installed , but only have the main 1 running full time. Only use the other program for occasional manual scans if you think there might be a problem ***********
