I just recently started to use my computer again after barely ever using it and never renewed my Kapersky subscription. Last time was in 2017. Today I renewed it and went to the Kapersky website and clicked on 'Store' and chose what I previously had, which was Total Security. I done bought it and now in the process of downloading what I bought, thing is I already have it on my system from 2017, an older version I would assume. Would downloading what I am now VS. what I do already have on my engine harm anything at all? Noticed once I done a bit looking around on the website and the software that is already here that all I had to do was renew it by entering my license number. Maybe things will be okay and should I delete my older Kapersky software when the one I am downloading is done? or will it somehow 'Merge'?
