run ewido and check for updates...then boot to safemode, you must run ewido in safemode for it to work properly...
I've never heard of alexa causing actual problems on a computer, it's only a search engine, and probably not as bad as some people make out.
About your mouse problem...
As it's a usb mouse, and this problem appears to occur at random, maybe it's something as simple as a loose connection...
If you get the problem again, unplug the usb connector and then plug it firmly in again, if you have another spare usb socket, put it in that one... are you using a usb hub ? if so, try to bypass the hub and plug it directly into your computer... or try a different usb mouse if you have one...
You could even try a ps2 mouse, but remember a ps2 must be connected before you switch your computer on ... and you must never unplug/plug any ps2 device while your computer is running ... unlike usb...
