My homepage is http://www.yahoo.com
When I run a system scan, I do not check for things that are not a threat.
Thus, usually only tracking cookies or spywares appear after a full system
scan. So, I don't think Ad-Aware is deleting my homepage or anything like that.
In the configuration window, there is the "Default" category.
In there, the homepage is listed as www.msn.com. So, I changed that
to www.yahoo.com and now Ad-Aware doesn't change it back to
Thank you, tg1911, for replying so quickly and helping me out.
