I have had to do two reinstalls on two computers in the last 6 months and on both it has taken me several attempts to get Norton Internet security to install, I am trying to get it back onto my laptop now and it just will not install.
I have got to change AV for sure, any recomedations!
You could go for the usual free one's that get recomended on this AVG, Avast, etc I use AVG on one of mine or I use McAfee on my main machine which I find very good (only anti virus and firewall not the whole internet suite I found the rest a bit resource hungry)
I used Norton for a few years and found it OK, but when the annual renewal fee went up to almost the cost of buying new, I decided to try Avast. I've been using that for a few years now and found it at least as good as Norton. When I installed Avast on the computer of a friend who's Norton subscription was about to expire it immediately found a trojan that Norton had missed!
