Take the 2-minute tour ×  I have noticed for a few months that
my mouse will randomly jerk across the screen. I'm super
paranoid about security.  Has anyone else experienced this, and
found out what causes it? It happens to me every couple of days.
The cursor will jump across the screen about 1000+ pixels. I
thought it was my mousepad - changed it, and that's not it.
Should I be paranoid about this, or is it just a
hardware/software issue?  This is on a PC with a Razer Naga,
wired mouse. The mouse worked for about a year before I started
noticing these issues. They have persisted even after a reformat
/ reinstall.  share|improve this question WHAT is your mouse?
Wired PS/2, wired USB, standard wireless, bluetooth...? If it's
wireless of any sort it could just be interference. I mean, if
you REALLY want to be sure it's not Big Brother you can just
disconnect from the network. –  Shinrai Oct 12 '11 at 23:08 It
may be too late, they're on to you, setup a Faraday cage,
disconnect and start DBANing your HDDS. NOW
