I have an HP Laptop running window 8.1. I've had issues for some time now. All problems are getting worse and more frequent. 

1. JUST RECENTLY MY MOUSE TURNED INTO 'COMB' OR STACKED HORIZONTAL LINES. This has makes the mouse really jerky and spastic. Prior to this unwanted changed my cursor would randomly freeze. I couldn't move the mouse around but I could sometimes bring up the drop down menu and if I could move something select-able underneath the mouse using the directional arrows, I could select it. CTRL+ALT+DEL, or pressing the windows button repeatedly 
2. AVG's scan has never found anything dangerous but has over 100 strange notifications--- These notifications are stuff that locked such as:: public files, 'InstallShield Installation Information', my documents, almost all of AVG's files are locked, 'hidden extensions' to windows apps, system volume and the list goes on
3. My computer is SLOW!!!------ I don't understand why my computer is so slow even when I cant see any programs going. In task manager 'Disk' and 'memory' are always at red or 100.
4. AVG, MALWAREBYTES, AND MCSHIELD SHOW NOTHING WRONG.

So what it boils down to is I suspect that there is something wrong with my computer but I can't pinpoint what. I'd like to make my computer faster and more secure. ANY HELP WOULD BE GREATLY APPRECIATED!
