I’m aware that spyware programs may try to hijack the browser’s default start-up page, but AdAware telling me every time that I’ve possibly been infected because my start-up page is about:blank (i.e., a blank window) is … irksome, given that that’s one of the options the browser itself gives you.
(Mutter mutter mutter …)
UPDATE: The new AdAware SE evidently lets you set up an ignore list. We’ll see id that does the trick.
