Not sure the computer will let me send this, but here goes.

About 2 weeks ago, it started. I first saw it using a little program
called Mail Washer. It started trying to log in to the mail server over
and over, multiple times a second. The "process" button wouldn't
function to let me delete the ones selected.
I quickly discovered it wasn't a mail washer problem. Firefox, windows
explorer, and Thunderbird weren't good either. In a browser, the open
tab flashes back and forth between the circle arrow(reload page) and the
X (stop). Again multiple times a second. Most web pages eventually go
white.
While this is going on, the desktop icons don't function. Double click
does nothing and right click opens up the menu that should come up when
I right click and empty spot on the desktop.
I "fixed it" once by bringing up troubleshooting. Troubleshoot windows
update, it found something and fixed it. Good for over a week.
Last night, it prompted me to install an update by restarting. It's set
to install updates automatically, so I don't see these requests often.
I shut it down overnight. Today I turned it back on. It took maybe half
an hour installing an update. I tried undoing that update but it
couldn't do it. Troubleshooting is no help this time.
Where do I start now?
