Since downloading Windows 10 on my Dell desktop, I keep getting updates notices pushing in from the bottom right of the screen. Each of these notices states "Unknown Application" or something like that. It then goes on to name the "unknown", which usually means nothing to me so I hit the 'allow' button, just in case it is required to run my computer. Today, as I was loading up a program that I downloaded yesterday and it worked yesterday, one of those "unknowns" appeared and it read 'pluginscontainer.exe'. I blocked it unintentionally and since then, that program won't load. Each time I try, I get the message "Pluginscontainer.exe" tried to load but has been blocked. Can anyone tell me please, how to unblock it? Oh! My security system is Panda but I can't find any way to track it down on Panda. Sincerely, Maxwellme.
