I just uninstalled AVG and Ad-Aware on my Windows 7 laptop after realizing that they were responsible for my out of memory errors. This box has 4 GB or RAM and I was regularly using 86% of it with only a few things open. After removed, I'm back down to 36% RAM used. I know that Windows will typically consume whatever is available to it vs. linux but this was ridiculous. Little red flag in my task bar now.
