I have been running Process Lasso on my desktop and laptop pc's for at least 2yrs. I find it uses very little in the way of resources and keeps the PC running smoothly. The process has not installed any malware,crapware like a lot of free tools do, it just runs in the background adjusting load priorities on the PC's CPU automatically.
