Intel has announced that the fix for the Spectre exploit can actually cause blue screens of death (BSOD) and crash your system unless you make sure everything is updated first — especially third-party antivirus. Leo says this is why it makes more sense to use Windows Defender and not use a third party app. They really do more harm than good.
The latest exploit "Spectre" affects every single chip made in the last ten years. At first, security researchers thought that the exploit only affected Intel processors, but it turns out this hack also effects ARM, AMD, and any other processor that uses speculative prediction. The white hat hackers who found the flaw discovered that you can use it to access valuable data including passwords and other information. Leo says that Microsoft has already pushed out a fix, and Apple's High Sierra has patched the vulnerability with a recent fix. Apple has also patched the iPhone and iPad.
