Ryan has a new Dell Inspiron 1440 laptop and he's managed to get a virus on it. Leo's guessing that it's due to downloading a mod for Minecraft, and it's likely Conduit. This isn't technically malware, but it's still annoying to get rid of. Leo's been there and he can get rid of it.
Mary wound up getting a program called Trovi installed, and she can't get rid of it. Trovi is a lot like Conduit, and it's a browser hijacker that often comes with free software. Some don't think it's malware, but if it tricks the user into installing it and makes it difficult to be uninstalled, then it's definitely malware. And shame on CBS, which owns download.com, for allowing this junk to be installed onto people's computers. Mary can remove it in Add/Remove Programs, but she'll also have to change her browser settings or it could come back.
Paul got nailed by a "search assistant" malware and he can't get rid of it. Leo says the good news is that it probably hasn't wormed it's way too deep. It's probably been installed as an extension into the Mac. He has to be careful because bad guys have made pages alleging to uninstall with a program, when it actually installs more malware.
Bob is having trouble with Internet Explorer and switched over to Google Chrome. He also dumped Adobe Flash Player and Reader. Leo says that those are two apps that are a target for hackers. The nice thing about Chrome is that Flash is built into the browser and is always up to date. It's also sandboxed so it can't get to the rest of his data.
George got a nasty piece of malware called "Search Conduit." Leo says that Conduit is bad, even though they swear they're legit. But if it takes over his browser and he can't get rid of it, then it's the very definition of malware. Leo advises downloading MalwareBytes from MalwareBytes.org. If that doesn't work, he should try booting into "Safe Mode" and try it then. If that doesn't work, he should try one of these:
