So I was at my parents’ house this weekend, and my dad asked a very simple question… “Could you take a look at my computer? I can’t run CCleaner.” I thought to myself… That’s great! He has been running CCleaner regularly! But when I sat down to take a look, things only got worse. Windows Update wouldn’t start, CCleaner wouldn’t start, Microsoft Security Essentials wouldn’t start properly or update, and AVG Free wouldn’t install. That is not good. Here is a list of tools I used to scrub his machine, and boy did i need them all, and for different reasons.
