I wish someone would point out exactly were the resouce problem is, imagined or real.
I previously had AVG installed and avast is no worse than that. The fact that it does more than AVG P2P, IM, etc. could make it appear that way.
But you must compare like with like when you are talking resources. So a comparison table could be meaningless unless you know what protection srevices they are providing.
I only use the Standard Sheild and Mail Protection providers and avast is every bit as quick as AVG and a dam site more effective.
From other threads in these forums it is pointed out that the Awil team are constantly striving to lighten the resource load yet retain the same levels of protection.
In life you have to make choices and compromises. Some of these are, the levels of support and speed of action in updating the product in response to customer feedback. From what I have see to date they are second to none.
If you are having resources problems check and see the junk you are loading at startup
(CodeStuff Starter) and why not invest in a little extra RAM.
