Hi, I'm Matthew Pierce. I'm a Software Engineer, and today, I like to talk with you about how to find and remove a hidden trojan from your PC. Now, trojan is a malware application that does things like installs other malware in your system and those pieces of malware or malicious software might do things like steal data or damage your hard drive or, or monitor your activity or maybe even get your computer installed in what's known as a bot net where it's kind of a robot that maybe, you know, at night when you're in bed, your computer's off doing stuff like spreading spam or other malware. So, you really want to get these things off there. But, if it's hidden, you don't know about it, maybe you just notice that your web browser doesn't work right and it redirects you to other websites when you're trying to go somewhere or it's sluggish or it crashes. So, you could have a trojan on there. And you don't know which one it is, you don't know which tool it is; so, the best way to approach that is to go after it with what I call a shotgun approach and use multiple anti-malware tools to go after it. Now, there's four tools that I really like to use and they're freely available on the Internet. One of them is SuperAntiSpyware. Another one is Malwarebytes. Another one is Spybot Search and Destory and another one is SpyHunter. They're all freely available; you can get paid versions too if you'd like, but you don't have to go with the paid versions. They have neat features, but, they, you don't need them to disinfect your PC. You just need to get these tools, download them and install them and when they install, they're each going to want to update what is known as a virus definition, or maybe they call them anti-virus definitions. But, they have definitions that they use to detect and go after these pieces of malware. So, you want to let them update those to the most recent versions and then, they're going to want to and disinfect your PC. But, you don't want to do that yet. What you want to do is get them updated and then reboot your PC into safe mode. Now, to, to reboot your PC in a safe mode, you just tap the F key, excuse me, the F8 key while it's rebooting and you'll get presented a screen like this that will show you the various boot options. Just pick safe mode. Don't go with network or any other type of mode that might give network capability in safe mode because this piece of malware maybe able to dial back to their home base or something and get help. You don't want that. You want to have them isolated; you want to give you anti-malware applications the best possibility of disinfecting your PC. So, once your up in the safe mode, you're going to want to run each tool one after the other. They're going to want to run in the, it'll take them awhile to do it. So, let them go and when they get done, they're going to present you with the list of what they found with recommended act, actions of what to do with them. Take the actions. Let the, the anti-malware software get rid of the problems first; but then, they're going to want to reboot. Don't let them. Just exit the tool, go onto the next one and just do that through the list of tools that you installed until you get to the very last one, let it reboot your system. And then, any hidden trojans or hidden, you know, whatever that they can find are going to be all cleaned off; your system will be nice and clean and since you use so many tools, you got some really good coverage on them. But, with all those tools installed now, they're going to want to compete with your system resources to protect your system. So, you're going to want to uninstall some of them and maybe leave just one of them installed so it can have its virus or anti-virus database updated on a regular basis. So, in case you get reinfected, you can just go and run it. But, then, the other ones you unin, uninstalled, don't delete their install packages; leave them on your system somewhere because some pieces of malware, you know, once you get them on your system they won't let you go out and download that stuff. So, if you do this, you'll have them already right there, you can install them and update them and you're, you'll be good to go. But, you want to get the stuff off there, you want to use a shotgun approach and you'll get your system cleaned up and you'll be good to go. So, my name is Matt Pierce; today, we talked about removing hidden trojans from your PC. Thank you very much for watching.
