What factors should we take into consideration while looking for ideal anti-virus software?

1) effectiveness
2) ease of updates
3) minimal use of system resources
4) cost

5) type of licensing
6) ability to control all roll-outs from one location rather than client by client
7) record/frequency of updates
8) length of time company has been in business

That is if you're talking software for a corporation

Personal I would place not being a resource hog near the top or at the very top of the list.

I used the free version of avg that seems to work fine and is not a resource hog and also every fews weeks I run a complete scan of my drive using Microsoft free defender program as a secondary check.

Oh the real time protection is provide by avg not defender as I had set defender real time protection feature to off and is using it as an on demand scanner only.

To me I am uncomforted with depending on any one vendor for total protection.
