Mid 2011 MacBook Air weird issue

[masterjedi73]

I woke up and Safari had mysteriously "reset" itself. All of my extensions are gone, but the history still remains.

Also, I have about 7GB of free space on my HD. It slowly decreases while the computer is on - in a few hours I won't have any until I restart the computer.

It's also been running slower than usual - web and processing.

Thoughts? I'm running 10.12.3

EDIT: When I posted this 50 minutes ago I had 6.8 GB free. I just checked and had 3.4. I restarted the computer and had 7.8 free. I noticed that many items in Keychain are missing, too.

Something bad is running in the background,I think...do a virus/malware check,and also check which apps that's not fully closed.

I checked for malware and deleted any apps I was no longer using. Got me up to 13 gb free. Now there are 6 free.

Checked if there is something running in the background?
