I have camera video clips saved on my computer that I always use to beable to open, now none of them will open. I click on the video clip, a file download box comes up, reads, Name: Movie.wmv, Type: Unknown File Type. I click run, then a Windows box comes up and reads, Windows can not open this file Movie.wmv. This never happened before, they always opened. I tried opening them in other ways, Quick Time, Windows media Player, nothing. I had a Vundo Trojan one time a had to delete alot of things to get rid of it, could I have deleted something that I need to open these videos? Thanks......
