Just for clarification: You are saying Avast5 uses less RAM and CPU than Avira 9?[/quote]
Where on earth did you get Avira out of what I wrote? lol.. I actually said nothing about Avira 9 or any other versions of it. I tried Avira once a year or two ago on one of my home machines and hated its interface (personal preference) so it didn't last more than a few days on my machine.
I"m talking about well known mainstream AV brands which is what I would normally compare a product against.
You have task manager screenshots to prove that?
Oh please.. do you have screenshots to dis-prove it? I didn't claim anything of the sort when it comes to Avira as I don't really know one way or the other. Perhaps I didn't realise that this was meant to be an Avira vs Avast type thread.

Please do not go into the "Avast provides more shields than Avira"!!
The only Shields that really matter, are the standard, and the Web Shield.
That's a pretty big statement you're making there Bootstrap. On what basis can you make a statement like that? What's totally unimportant to you might be exactly what someone else is looking for and needs.
Avira free does not provide a web shield,and Avast! 5's is unworkable.
Then I have a total of 14 workstations here running an unworkable antivirus then. I must be some sort of magician.

And what relevance is a comparison of Kaspersky Security SUITE,with Avast free? or paid AV?
Computer performance during active real time protection by a proven well performing (protection wise) product is the relavence - something that would be important to just about anyone that enjoys speed, which in my opinion, would take in just about all commputer users in general. The two I mentioned, Norton and Kaspersky, are proven peformers, both with respectable scores on independant AV comparison tests I've read in the past.. both however can also, and do, grind a computer's performance down to frustrating levels. This I know from personal past experience, which is why I chose those two as my examples. Avast on the other hand, hardly makes a difference to a computers performance at all in my experience, apart from when it's doing a full scan or updating itself.
I thought your complaint was that Avast 5 was made on super fast new computers and therefore unworkable on older machines? That hasn't been my experience with the product at all.
Cheers...
