Security
Much as it's moaned about, I've been using Norton Internet Security for as long as I can remember & installed it on more PC's than I can remember. Other than an iffy upgrade (once) & some spurious application blocking (rare) it's never caused any issues & never let anything in.
The iffy upgrade was mid subscription & wiped my remaining time to renewal (about 100 days) - a call to Symantec got me 150 days without any issue!
All I would say against it is;
Don't use it on a sloth of a PC.
Don't go for the easy online renewal - it's cheaper to get a new retail pack.
