What are the essential tools you always have handy when attempting to fix someone’s PC?


Specifically, I’m interested in knowing what tools you keep loaded on your thumb drive when asked to deal with a family member or friend’s personal computer issue? Off the top of my head, I can think of things like:

  • AVG
  • Advanced WindowsCare
  • SpyBot
  • etc.

…but this question is not necessarily limited to virus/malware/spyware issues.
