I made a mistake, and, in an instant, I went from having a great night to being in an endless Security Tool nightmare. This nasty software is almost impossible to remove. On a recommendation from a trustworthy site, I ran the free version of Malwarebytes Anti-Malware in Safe Mode. My computer is back to normal, and I'm a happy camper! I am grateful that MB made a free version of MBAM available and that it works so well. The generosity of MB made me happy to pay for a license today. I LOVE that it's a lifetime license. MB, thanks for being there when I was in trouble and helping me out of a nasty bind for free!
