I was browsing the internet in firefox all of a sudden I could not run any programs. explorer.exe was blocked from running any program. The only exception appeared to be it would let me restart firefox and thunderbird, both of which were running when the problem started. The blocking was logged as “create process alert suppressed” as I had parental control on.
A reboot put things to right.
