I have a couple of mouse cursor issues. First, about my system. I have an ACER Predator G3620 desktop tower computer running Windows 7 Home Premium 64-bit SP1. It has 12GB RAM, the HDD data are ST2000DM001-9YN164 [Hard drive] (2000.40 GB) -- drive 0, s/n W1E0Q9G1, rev CC4B, SMART Status: Healthy, here is the video card and DISPLAY data       NVIDIA GeForce GT 630 [Display adapter], Acer X223W [Monitor] (22.0"vis, s/n ETLDX0D0119180A3748512, May 2009), and the sound data are NVIDIA High DEFINITION Audio Realtek High Definition Audio. I run comodo firewall, avira antivir, and use Malwarebytes antimalware. There is no windows cd. The mouse is an Echostar. It has worked fine with this system for over a year.

The mouse cursor will stick in place on the screen at random times and places and I really have to move the mouse around to get it unstuck. This happens several times a day while I am working, sometimes several times an hour. The other issue is that out of no where the mouse will go all over the screen opening up and clicking many things at once. I noticed the last time this happened I banged my mouse on the mouse pad because it had just been exhibiting the former issue. I have to reboot to stop it. I ran my A/V and anti-malware but it still does it a few times a week or even a couple times a day sometimes. I am the only user. I have time warner cable broadband Internet. I have not done anything inside the case except to blow it out with an air duster.

I have tried the usual steps including DISK clean, CCleaner, scan disk on boot, SFC /SCANNOW, unplugging and reattaching the mouse, rolling back the video driver and reinstalling it. Any suggestions for either or both issues are very welcome.
Have you tried using a different mouse?
