If my ex called asking for tech support I'd tell her to go fuck herself. Nah, but really, if she did call, I'd give her the name and number of a reputable local tech and wipe my hands of the situation. We're ex's for a reason-I'm not here at her beck and call to do favors for her. And no, I don't have kids with her but even if we did the only way she's getting any IT assistance from me is if it were the kids computer. And even then, I'd be reluctant-because of the potential drama with her not the kid :shrug:

To answer your question, SpyBot Search and Destroy is the best I've used.
