David has been having issues with Google Redirects, which takes him nowhere. Is that malware? Leo says yes. It's a common practice of evoking the names of trusted companies. It's most definitely a virus or malware designed to redirect him to either more malware laden pages or advertisers that they want. But he'd have to install it. This is why it's important to run as a limited or standard user, and not an administrator. David tried to uninstall, but it won't. Leo says that's because malware doesn't want to be uninstalled, so they make it very hard to remove.
Ray is concerned with security on his tablet, and is wondering if he should have antivirus for it. Leo says that mobile devices are designed in an era where malware is a serious threat, so these newer operating systems are inherently safer because they tend to be sandboxed. If he still wants some added protection, LookOut is a very good antivirus app. That being said, Leo doesn't use an antivirus program.
Mark hears that when downloading Java, junkware downloads with it. Leo says that Java is now being bundled with adware, so he should make sure he unchecks the option. Better yet, he shouldn't download and install Java unless he needs it.
He should also make sure that it doesn't load automatically in his browser, which is a security issue. Java uses Kommodia, which actually breaks the encryption technology of a browser. So Marks' wife should remove it immediately.
With news that Lenovo has been caught using man in the middle attacks to insert adware into user browsers, Leo says that we must send a strong message to them that this is unacceptable. Lenovo claims the Superfish "add-on" was only added to consumer products to provide targeted ads in browsers, but Leo says it's malware and it deliberately violates the trust between consumers and manufacturers.
After getting caught putting a piece of malware called Superfish on all their laptops, Lenovo has offered apologies and released a removal tool with which to remove it. Leo says that Lenovo had been putting malware on its machines that makes it possible for a 'man in the middle attack' to reroute customer's personal traffic to Lenovo so that it can insert ads. Leo says that's inexcusable and nobody should ever buy a Lenovo brand computer again.
A sophisticated malware attack has robbed hundreds of banks in 30 nations, including the US, Russia, Japan, and Europe. According to a report from Kaspersky Labs provided to the New York Times, upwards of $300 million dollars was stolen, which could make this one of the largest bank heists ever.
Back in 2013, in what has been the largest hacking theft in history, hackers used malware to break into the computer networks of several major banks and stole over $300 million worldwide, and could actually be three times as large, the largest theft in history. No bank has come forward claiming they were victims and security firm Kaspersky has been retained to investigate. Leo says these attacks happen all the time and that Banks cover it up to prevent clients losing faith in the institution. How did it happen? It appears to be the old phishing scam with bank employees as the target.
Jay wants to know if removing viruses is the same between Mac and Windows. Leo says that there's a debate that Macs are either more secure, or are a smaller target because there are fewer of them. Leo says that malware writers are going to write for the largest segment of computers. But OS X is based on Unix and that's more secure than Windows. OS X also has an administrator requirement when installing software.
Don runs Windows 7 on his laptop, and was running Avast AVS which found a "Dropper GEN" virus. Leo says it's a nasty trojan virus. It's a dropper package which goes out and gets more malware. So if it's a true dropper, Don has problems. Don should try running a second screening using Microsoft's Malicious Software Removal Tool (Start-Run-MRT.exe-Enter). He could also try Eset's online antivirus screener as well, and Eset has a removal tool that also removes itself when it's done. Don tried running Kaspersky and it didn't' see it. Leo says that could mean it's a false positive.
Karen is having an issue with an online stalker who has hacked into her computer and has been deleting her files and other things. Leo suspects that Karen isn't really being hacked unless she has incurred the wrath of someone who can do that. More likely, what may be happening is that she's got malware and she probably should format the hard drive and reinstall Windows from a known, good source.
