Thank you very much for your help. Anyway, this doesn’t answer all of my concerns. I was asking about maximum possible security that Kaspersky software for home users is capable of, especially in detecting possible malware stated in the subject of my question. I am fully aware that such things can’t be explained in a reply to my post, so I would be very thankful if there is some kind of a manual (possibly in pdf format, possibly very huge 😀 ), where such things as explained in details. Then again, I read elsewhere that no security software can confirm with 100% accuracy that there is no malware on the computer or phone. Is this true? I can find the links and post them in my next reply if required.
