The following may be unrelated to this forum topic.... I don't know?
Mid-December my Win7 64 Pro desktop started just freezing, apparently at random. No keyboard or mouse action, just a frozen display of whatever I was doing. (In particular, starting Windows Live Mail 2012 always resulted in a lock-up while the program was opening). I had to long-press power button to re-boot. (Very) Long story short I restored the PC using a Macrium reflect image from February 2018.
This did the trick until I gradually caught up with Windows 7 updates in late December and found the freezing problem recurring. Intenet research revealed that KB4483187, a critical security update for Internet Explorer 11 was implicated in causing these freezes (AskWoody web-site), so I uninstalled it, using system restore, and my PC was again back to normal.... no freezes during Christmas break and right up until this morning!
But today I've got a strange issue.... if I go to the Lloyds bank Log-in page in Google Chrome the page becomes unresponsive and I have to "Close the unresponsive program", (mouse still works to do this.) When Chrome has been closed it will not re-open until I shut down and re-start the PC.
Then I found this forum topic. I've now discovered that every time I try using the Lloyds (or "Halifax" very similar) Log-In page with MalwareBytes Web Protection ON, the page freezes. But if I Iturn OFF Web Protection the Log-In pages work fine.
I've turned OFF Web Protection, Installed the MalwareBytes Chrome browser extension, and crossed my fingers.
