I've DLed and installed MQ2 on one of my computers, but it's gone fritzy on me and I'd like to unload MQ2 and reload it again. Other than by rebooting my entire computer.. Is there a way to unload it safely? Apparently, my computer was working fine up until I installed MQ2 onto it. Now I keep on getting odd messages with my firewall as well as when I try to shut down my computer or restart it. I figure if I unloaded MQ2 and reloaded it, that might solve the problem. Unfortunately, MQ2 does NOT show up on my Install/Uninstall of Windows. By the way, I was told to ask what exactly the authorization codes do exactly or allow others to do to my computer. Would it enable someone to hack into it at all?
