Craig has a ton of adware on his PC from installing software. Leo can't stress enough how important it is to be careful where you get your software and files. And since you don't really know what you have, you could have opened yourself up to far more bad things. Leo suggests turning off all extensions, delete them from your extensions folder, and run as a limited user. Look in your add/remove programs for entries you don't recognize and remove them.
Ron checks out eBooks on his PC and he's now getting popups demanding he install a Media player 12.2. Leo says that it may also be a malware installer or Adware that's trying to dupe you to install it. Ignore it. Leo says they are so annoying and malicious, it should be considered malware. And it's likely that Ron has got a Browser hijacker on his PC as well. So he should go into add/remove programs or programs/features control panel and uninstall anything he doesn't recognize. And stop running your computer as an administrator.
Jay says his wife's computer will make the "swoosh" email sound frequently when there's no email being sent or received. Leo says to make sure there's no sent items in the email sent folder. Also, check in the settings to see if that sound is being played for other things the computer does. There's an option called "play sounds for other mail actions." Make sure that's disabled. Also, Leo advises using a program called "Little Snitch" for the Mac that will advise him if any nefarous activity is making an outbound connection, but it's probably not that.
Dan uses Windows XP and is worried about security once Microsoft ends support for it on April 8th. Leo says that there will only be two more security patch Tuesdays between now and April 8th and once that's done, XP will no longer be supported. Leo says that once that happens, all XP users should pull their XP computers off the Internet completely. There are bad guys who collect flaws and exploits and take advantage of holes in the system. One such nasty thing is Cryptolocker.
NBC's Richard Engle did a story that mobile phones and computers were hacked the second people arrived in Russia for the Olympic Games. Leo says that the NBC story was completely false, and had been faked to get the audience looking at Russia in a particular way. Leo says that they would get hacked if the reporter deliberately went to a malicious site and downloaded the software that would infect the computer or mobile phone. Engle was a thousand miles away in Moscow when he did it.
Suzanne got bit by a scammer calling from "Microsoft." The worst part is that she's a security analyst. Leo says that Suzanne shouldn't feel so bad since chances are that they are actually off duty tech support staff moonlighting as scammers. They social engineer victims and scare them into installing something on their computer. The CLSID is not unique. Then they show the user the "Event Viewer" which logs all errors. It looks worse than it is and the scammers rely on that.
Morris clicked on a link from an email that got sent to him, but Firefox won't let it open. Leo says that's a security feature designed to protect him from being taken over by hackers. Leo says that it's likely that Morris may have gotten lured by a bad email and Firefox saved him from it. Leo says it can be disabled, but it protects him and is for his own good.
Larry has a flashing blue and gold shield that wants him to install a java program. He says no, but it pops up again a few minutes later. Leo says it could be benign, or it could be a concern. Java is a programming language and many websites use it. But Larry's computer is set up correctly to ask permission to install it. It bothers Leo that it says "Publisher unknown," and not "Oracle." Leo says to keep saying no is the best move.
James found a list of serial numbers for Sony Vegas. Are they legit? Leo says no. Vegas is a $700 software package and if he downloaded the trial version and put a serial number in that he found on the internet, then that's piracy. This isn't really something James will want to do, especially if he's starting his own video business. There's also the risk of getting malware from downloading software from unofficial websites.
Frank has found a folder on his computer that seems to be part of Google, but also has the word malware in it. Leo says that it's Google's anti phishing file folder that's been saved from running Firefox or Chrome. It's a database of sites that are blocked when he's surfing the net. This folder is safe, but it's a good thing that Frank suspected something.
