Some time back, I let Firefox install an update. Uninstalled it a short time later cause I was getting flooded with ads. Happened again. Tried to ignore it and not install it but it was like my computer was taken over by Microsoft, couldn't do anything. One window had something about Trojan something couldn't read it windows were overlapping. One said I needed to allow the Firefox update or they would freeze up my computer. I couldn't do anything so used the task manager to kill it all. Then allowed Firefox to update. Now have all the ads again. Also, in Firefox settings, something new. Top of page, message says: "Your browser is being managed by your organization."

Anyone tell me what's going on. Had some problems with PC Matic a while ago (not virus or anything), just decided I needed a change. When I tried to uninstall it, it was a real mess. Totally locked me out of one of my other computers. Thought this one was OK. The other one will now boot but will not make it through a restart unless I skip the part of the restart that does malware checks
