Beta testing security software requires a virgin system, no reg cleaners, no hacks, no active security software. Less is better, as security software can conflict with just about anything & everything, especially other security software. Conflicts result in strange issues that are hard to narrow down & waste time & reseed hair lines. CPU usage issue is resolved by right clicking the tray & exiting the program. After restarting it the CPU usage is nominal.
I have been testing software for over 15 yrs & have Excedrine Migraine to prove it.
