It is possible to get out of sync and you would need to call into support to get sync'd again. Lately my Win 10 gives me a message that it has found a file named "SOFTWARE LICENSE SERIAL NOS" on my disks, presumably thinking it is a suspicious file it wants to report to Microsoft.
And IF which is a big IF someone did get to guess your device number, they would still need your password, pin etc. BTW this file contains all my legal software and download server account serials.
I thought it might be conflicting with AVG free, so i removed that and tried to do it again, but it goes no further than %2 Should i just forget about kaspersky and get Norton or one of the free internet security programs? I do need a qood internet security software as I do internet banking all the time and do a lot of downloading too. Norton goes beyond the call of duty and tries to erase any file with a suspicious name. As far as the comment goes that Norton detects suspicious files and erase threats, isn't erasing threats the job of an antivirus?
Know that you will most likely never even encounter most of these so-called threats, reality is that a computer can do just fine without any antivirus installed in the system unless you are some sleazy pervert who likes to surf a lot of adult streaming websites or risky websites to download cracks, patches, sql injections for hacking and what not.
I've tried looking for an answer, but i can't find one, so hopefully someone here knows what is happening? and yes, you shouldn't use two internet security software at the same time. I wouldn't advice you to use Norton or any free internet security software. And just for the record I have used both Norton and Kaspersky and this whole high resource utilization thing about Norton is an utter nonsense since I have hardly noticed any difference with the performance from start up to the running of multiple process smoothly.
