The ESET Family Security Pack 3 includes: 3 computers + 3 Android devices for $84.95 fpr 1 year.
I just grabbed a 3 year licence for 3 PCs + 3 Android tablets which after the 20% discount cost me $143.16 AUD to cover my Windoze partition (for gaming) my wife and son's PCs and each of our Android tablets including anti-theft software.
I always used to use freebie anti-virus software until I go the AFP virus on two different machines. One I was able to fix manually by booting into LINUX and going into my Win7 system files (via LINUX) and manually deleting the culprit file but the other one was tougher to find. I tried eset NOD32 free trial and it worked. Since then I have been thinking of actually paying up for Anti-virus software for the first time in my life and finally took the plunge. LOL!
The prices vary depending on your needs and whether it's for home or business but the 20% voucher seems to apply to all licences.
Hope this is of use to someone and that I that don't sound like a total fanboy!
P.S. I've always thought eset's artwork looks kind of cool ;-)
I administer a mid-size network of PCs via the ESET Admin Console. Great product.
