Operating System: Windows 7 Untimate - 64 bit

System Specs:  1.86 GHz Intel Core 2 processor, 3 GB RAM, 1 TB HD

 

Recent intermittent problem seems to be browser related (I use Firefox almost exclusively - current version is 72.0.2). I can't associate it with anything except it seems to occur several minutes after I open a Web page where I've not been before. I do check new sites before visiting with Webutation to make sure they are safe.

 

The HD light comes on steadily and the system slows so that it looks like games and such are running in slow motion. I try to close the browser and it freezes for several minutes. Can't open Task Manager right away, but will open eventually. Everything looks normal there.

 

Also, when this happens and I try to shut down, there is a black screen that flashed for an instant that looks like it says "Waiting for background programs to close". So something is running which the Task Manager doesn't indicate. When this situation happens it takes a lot longer than usual to shut down.

 

Any idea what's going on?

Try running Firefox in Safe Mode:

See if you have the same problem.  If not then one of your extensions is at fault.  Try turning off about 1/2 and restart Firefox.  If still no problem, shut off 1/2 of those remaining.  Try to locate the bad extension.

 

If that doesn't help then we will have to move this to the Malware forum so we can run FRST so I can see what is going on.

Th only extension I have is uBlock Origin. I did post a FRST scan a few weeks back, but I did not receive a response:

Also, now MSE will not perform scans. This week I tried to do a scan and although the HD light came on, even after 10 minutes there was no green in the activity bar and no running times displayed.

I have replied to your post in the Malware forum.  Going to need a new FRST scan after all this time.  When you replied to your original post you took it out of the Unreplied Posts list which is how we find new posts to answer.
