All of the applications, with the exception of the wonderful Malwarebytes, where way over this average user's capability. Probably easy for most IT Pros.

We have such a wide variety of readers here. :)

Once again you've added some really helpful utilities. Your website is the first one I go to when I have computer problems and in need of a particular free program.
Thanks for all your good work!

Thank you for your kind words, they are appreciated. :)

Great stuff. Thanks!

I'm glad you like it. :)

Good stuff here. In the "15 Tools" article, the 14th utility is ESET System Inspector, but the link takes you to the 15th item which is a Microsoft Debug Diagnostic utility. You will need to google for the ESET utility in order to find it.

I've added the link to ESET, thank you. :)
