Computer lagging, freezing the last week or so

Sometimes it locks up for a minute or two, can't open anything, HD light comes on. Checked Task Manager and my browser shows high CPU usage (see attached screenshot). I have a desktop running Windows 7.

Assuming you rebooted. Have you tried anything else? Run a virus scan or something?

Windows 7 is a risky proposition since Microsoft stopped supporting it.

How old is your computer and what type is it?

Why didn't you update to windows 10?

You have 7 Firefox instances running, highlight each, one at a time, and click "End task" bottom right.

Reboot.

I bought it as a refurb from a computer fixit shop in 2012. They probably installed the OS with a blanket license, so likely the case doesn't go with the updated software. I have an inquiry in at GeeksToGo web site. Awaiting advice there.
