Sorry to sound dense about this, but I'm still not sure whether Malwarebytes (the FREE version) checks for this DNS changer malware. I've checked my PC at more than one "checker" site (all found on the FBI's official web site), and I always get a green background/banner/border/whatever that says it APPEARS I do not have the malware on my computer. But it ALSO says that if my "ISP is redirecting DNS traffic for its customers", my PC may STILL be infected. One reply in this string just gives complicated instructions about how to remove the malware (I thought that Malwarebytes automatically removed malware when it found it in a scan). The last post says Malwarebytes DOES remove the DNS changer "on the computer end". I thought to myself, "what other end IS there?" It also says that it is a good idea to "scan your setup" at the dcwg.org site, "as this can also change settings in a router if you use one". Why would I want the dcwg to change my router settings?! I have been running Malwarebytes free version for about 18 months now. It has never, EVER said that it found a single instance of malware. That's either very good (very lucky)...or the free program, which I DO update regularly, isn't really able to detect current malware programs.
