Personally, I can think of nothing more satisfying (or infuriating) than cleaning up a computer that’s been completely worked over with all kinds of bad stuff, be it viruses, spyware, etcetera. This is especially true if you happen to be getting paid to do it. The problem comes in when you find out that the tools you have to do the job are inadequate. What happens then? You spend valuable time searching for something you hope will work after being downloaded through an infected system rather than having the appropriate tools to render the system sufficiently sterile in the first place. There is, however, an easy way to avoid this. Check various sites such as Technibble.com and MajorGeeks.com as well as various reputable antivirus and antispyware websites such as AVG, Avast, and Spybot Search & Destroy for up-to-date versions of their latest free versions. Keeping your toolkit current and stocked with new utilities will help keep you from added frustration.
