Joe wants to know if Microsoft's antivirus can really do the job. Leo says it can, but he really doesn't need it if he's careful. He'll want to be sure he's updated everything -- OS, browser, Flash, etc. Microsoft Defender is a good thing to run, but nothing can completely protect him from his own online behavior.
Jim has a friend who's website has received a message that their website has been hacked. Is this warning legitimate? Leo says it probably is. Most managed providers offer that feature, but there's also independent monitoring services like Site Lock. They'll monitor his website, but they won't patch it. He'd need to have a service that goes through all of his code to make sure it's patched and nothing remains of the virus that may have infected it. Jim should check out Qualys. They monitor and repair the site should it get infected.
Brett has a Dell computer and wants to know if there's an open source program that can speed up his computer like Dell does with Click to Fix? Leo says that Dell doesn't share their secrets and Leo doesn't think that it's safe to use a third party open source option for this. Dell's Click to Fix knows its own hardware and as such, can do a targeted fix. Open source stuff can't do that and can be overly aggressive and cause more problems than it fixes.
Donald went to a well known adult site on her iPhone, and now he believes his phone is infected. He gets a popup that says "call for Apple support" and they want $35 to fix it. Leo says it's not usually possible to hack the iPhone, so it may be a modified Safari home page instead.
Al recently upgraded to Windows 10 and Chrome has been giving him error messages preventing him to go to certain sites. Leo says to trust that. It's likely that the site has some malware code in it that will cause issues down the line. It could be a generic warning though. To be safe, Al shouldn't click on any links. Instead he should hover over it to see what the actual link is. It's possible to spoof a link with HTML code. In fact, Leo suggests turning off HTML in his email client. Leo suggests also using Thunderbird. It will give him the option of text only.
Nicki saw an .exe file she didn't recognize in her system tray. Leo says that system trays hold icons of programs that are running and if she hovers over them, she should get some information. It could also be an error. It's causing security issues and Windows won't load her antivirus. It could be an infection, so she should update her antivirus or use Microsoft's Malicious Software Removal Tool.
Kevin's mom went to a website and got a virus alert. She then called the phone number on it and they had her install something, which gave them control over her computer. Leo says that's a common scam. They probably installed a virus and maybe even turned her computer into a bot. The worst part is that they took her money and now have her credit card number. She realized her error and called him, though, and Kevin has since changed her passwords. She has trouble remembering passwords. Leo says many do and they end up using the same password over and over.
Michael is getting a lot of phone calls from overseas being told that he needs to upgrade Windows. Leo says it's a scam. Microsoft will never call him. These calls are trying to get people to sign up for a support contract and even worse, they could install malware on his system if he falls for it.
Proxies are usually used by companies to see what you're doing. And if you're getting the popup, that means you may have been infected or compromised. Leo recommends Reisel back up his data. He could just turn proxy off, but he won't know if his system had been compromised, so it's best to format the hard drive, reinstall Windows, and then run updates.
Tom has a Samsung Galaxy Note V with Sprint. Lately he's been getting a warning of being infected. Leo says that's nonsense. We're starting to see these popups in mobile phones like we did running a browser in Windows. It's likely a phishing attempt to get him to buy something. Tom should just keep his phone up to date when a patch is offered from his provider, and he'll be fine. He's not infected.
