Steve bought a Lenovo Windows 7 PC a few years back. He recently wound up getting the Taplika virus with non stop pop up ads in his browser. Leo says he'll need to install "VPlay" from Add/Remove programs and then remove Taplika from his browser. Technically it's not a virus, but a browser hijack and that should get rid of it. VPlay is a Windows service, and that is very insideous. It's going to make it harder to get rid of. He can find more information at malwaretips.com
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.
George wants to know how to avoid malware. Leo says to practice safe computing. Here's a few steps:
Lee gets a popup that says his computer is infected and he can't get rid of it. Leo says it's a scam, and Lee should never call the 800 number that pops up. Lee went into the task manager to kill the popup, but it kills the browser as well. Leo says that Chrome should be catching the popups and stopping them. He's now getting a popup with a bluescreen. Leo says that's a clever ploy, but it's not an actual "blue screen of death." It's just a window.
Elizabeth wants to undo whatever her nephew did to her PC after he came to visit. He's got mad computer skills and she caught him rummaging around her computer without her permission. Leo recommends backing up her data, formatting the hard drive and reinstalling Windows from a known good source. That way any modifications he's made will be wiped out.
John is getting phone calls about unusual activity on his computer. He was told it was from Microsoft. Leo says it's a scam, and it's usually done by actual tech support people who moonlight with phishing scams through the Microsoft Event Viewer. The idea is to get users to see the "red x's" that are actually normal events in the viewer. They fool people into to giving them their credit card, charge them $300, and then they use the remote access to install malware on the system.
Frank got fooled by a Phishing popup. He called the 800 number that was associated with it and they charged him $300 to "fix it." Leo says they were pretending to be Apple Care. It's a scam. Frank suspected chicanery and called Apple Care, who confirmed it was a scam. Leo says that's a smart thing. So he turned off the computer. He doesn't see anything wrong with his computer, but what should he do? Leo says that chances are they probably didn't get far, so Frank is probably OK.
Alan just installed Windows 10 on a few computers and wants to know if there's any reason to install a third party antivirus program with it. Leo says that Google has done a study about this, and they've found that most security experts believe antivirus software gives a false sense of security and doesn't guard against zero day exploits, which are the real threat now.
