But he shouldn't ever pay the ransom.

How can I uninstall an unwanted program?

Walter from Huntington, WV

Episode 1257

Walter got an icon on his Windows machine called "Launch System Healer," and later found out it's malware. How can he get rid of it? Leo says that the problem with malware is that it can be very difficult to get rid of and even if he does, he may not get rid of all of it. But it's called a "PUP" or "potentially unwanted program." It should have an uninstaller, so Walter should look for that. Chances are, Walter accidentally installed it when installing something else that had its own custom installer.

Scott from Ventura, CA

Episode 1239

Scott wants to know if doing a restore would get rid of any malware that may be on the system after its been compromised. Leo says yes, it will. Those popups are trying to get you to call them and install software. So if he didn't do that, he's probably OK. But if he did, not only will he need to get rid of the malware, but if they charged him, they will now have his credit card information. So he'll not only have to backup his data and erase the hard drive, he'll have to cancel that credit card as well.

Leo says that's a clever ploy, but it's not an actual "blue screen of death." It's just a window.
