Isn’t it disgusting that we have so many words for the horrible things that bad guys dream up to muck up our computers? Jeeze. For Computer Security Day on November 30, take steps to protect your computer with these free tools.

Malware is software such as viruses, worms, Trojan horses and spyware. Malwarebytes has been the best free tool in this category for years. It’s the one I use. I like that you can upgrade to get robust protection from ransomware, the programs that literally hold your files hostage and make you pay to get them back. For more overall protection, Kaspersky Security Cloud Free ranks the best.
