It's not a matter of resource usage. It is a matter of responsiveness. Not all people are equally sensitive to it. I can see it everytime, when i try to quickly go through many folders. Even the "tick" sound that windows makes when you go through becomes less snappy.
Even the test authorities that live out of antivirus (their tests are financed by the vendors and partecipation to each test costs more than 10.000 euros), admit it:
^ Mind you, the same tests, show all AVs, in the 95%+ detection rate, which is ridiculous in real life, but like i said, they are paid by the AV companies to make these tests, so they can't have anyone look "terrible". "Bad antivirus" = "no money for testing for me".
You can test yourself using AppTimer, before and after installing antivirus. The lag is very simple. For any action you do, first it must pass from the scanner. This is what introduces the lag. Some antiviruses also have sandboxes or miniHIPS. This means, that the AV driver hooks on all API calls of windows. Or at least, the ones covered by the miniHIPS. So each action an exe performs for example, must first get the "OK" from the AV driver. In whitelists programs it must be checked against the whitelist and the bigger this is, the more the lag. I WISH it wasn't true, but it is. I 've made all kind of tests in over 10 years hoping that it was a "nocebo" effect that didn't exist. Unfortunately, i always had the same feeling, then avcomparatives came, AppTimer confirmed. HTTP scanners from AVs also add lag to browisng. I had the Avast developer admit it in a forum saying "there is no way not so have some lag, from the moment that all your traffic must first be inspected on the fly".
This is John McAfee's words after he abbandoned the McAfee Antivirus company:
