Have you restarted your computer recently? You should restarted about weekly to be sure any pending updates are installed. Not doing so can lead to the computer behaving in an unpredictable manner. Restarting over the weekend is a good time.

A brief recap of the problem: modern processors perform speculative ex*****on. To maximize performance, they try to execute instructions even before it is certain that those instructions need to be executed. For example, the processors will guess at which way a branch will be taken and execute instructions on the basis of that guess. If the guess is correct, great; the processor got some work done without having to wait to see if the branch was taken or not. If the guess is wrong, no big deal; the results are discarded and the processor resumes executing the correct side of the branch.

Microsoft has suspended delivering the latest Windows update to certain systems with AMD processors after reports that the update was causing the machines to crash with a blue screen of death when booting. The update contains countermeasures against both the Meltdown and Spectre attacks; although AMD systems are not affected by Meltdown, they're vulnerable to Spectre.

Blue screen crashes on decade-old AMD chips seem to be widespread.

Early last year, a piece of Mac malware came to light that left researchers puzzled. They knew that malware dubbed Fruitfly captured screenshots and we**am images, and they knew it had been installed on hundreds of computers in the US and elsewhere, possibly for more than a decade. Still, the researchers didn't know who did it or why.

Fruitfly creepware turned on cameras and mics, automatically detected p**n searches.

It seems Microsoft pushed out updates yesterday. That means you should restart your computer today or Thursday. After that you may not have a choice of when the computer will restart. You don't want the computer to restart while you are making entries into Quickbooks, for example.
