This popular expired deal from Feb is back on again (same price for first 2, $2 more for 3rd).
Internet Security 3PC 1-Year $12
Internet Security 3PC 2-Years $19
Total Security 3-Device 2-Years $26
Personally, I recommend choosing deal #2 over #1 as its better value for money.
Choose Deal #2 if you just want to protect PCs, or #3 if you want a mixture of PCs and mobile phones.
I have been using Kaspersky for a few years now, and pretty happy with it. Doesnt hog resources like Norton.
Includes anti-spam plugin for Outlook email - but has to be enabled via the Settings.
I believe you can buy multiple codes and stack them, eg for 4 years, just be careful not to activate a 4th device as that would start consuming the 2nd 2-year license early. Or buy but dont add the 2nd license until near the renewal date.
good
