I've had this problem before,
and night, EST around 11PM -12 AM my system became quite slow, I check
processes on Task Manager and saw that svshost.exe was in the 90's
I closed by browser but it remained there so I diconnected my connection that bought it down,
It may have been automatic updates loading the update that I can choose to download.
In any case I looked for what may have happened in events but could not decipher anything in
particular, but did find this that occurred after, . . .

Message: The System Restore filter encountered the unexpected error '%2' while processing the file '%3'
on the volume '%4'. It has stopped monitoring the volume.
System Restore encountered an error when backing up a protected file. This error causes System Restore
to stop copying files and purge all existing restore points. System Restore will automatically restart
after the next restore point is created.
System Restore will restart monitoring file changes immediately if you manually create a restore point
(if one has not yet been created).
To manually create a restore point
Click the Start button, point to All Programs, point to Accessories, point to System Tools, and then
click System Restore.
Click Create a restore point, and then follow the instructions.
What might this be ?
I have noticed a couple of times that my system restore had no restore points when I went to restore.
