Georgi, You had me install and run at least 8 applications to clean my computer. I didn't bother to read about any of them while following your directions. I will read about them, but I would appreciate your explanation about their use. I'm not looking for a lot of detail, just a general idea about the process. We ran Revo Uninstaller, FRST, AdwCleaner, JRT, Malwarebytes, HitmanPro, ESET, and SecurityCheck. What did they do and what was special about the order in which they were run? Should I run any of these periodically myself? Is Revo Uninstaller better than the built-in Windows application? I have Norton installed on this machine but I wasn't using it. It had started being a little more intrusive than I liked. I discussed this with a technician at a Microsoft store and was advised that the built-in Windows applications like Defender were good enough to protect against most things. Should I start using Norton again? What would a better protection strategy be, in your opinion? One of the sites I visited when I realized I needed help was bleepingcomputer.com. Of course, I see it in your signature line. Is it a pretty good and trustworthy site for information and help? If I wanted to learn more about malware and protection, would you recommend the tutorials on bleepingcomputer as a good place to start? Mike
