Hi, I have two computers, one laptop with W8 and one destktop with W7. Since the last two weeks, I can't execute any exe file with the shield icon on it (shorcut or file), if i try a pop up windows open wich says Unknown Error. They DO open if I do right click and Run as Administrator. Both pc have antivirus software, W8 notebook came with trendantivirus and the W7 desktop have AVG free. I have google the problem, but found no answer.
