Hi all, I have a problem myself. I already disabled smartscreenfilter, but I tried to download opera browser, and it was still marked unsafe. I was suspicious and tried another browser; i tried installing chrome and safari, both the the same result. When I download opera, it downloads fine until about 98%, then it stops. After a while, it "runs a security scan" and this pops up: opera_1111_en_setup.exe was reported as unsafe. I downloaded opera from their main website; it is legit. I tried downloading other things out of curiousity, and nothing seemed to work. I haven't been using a lot of bandwidth, so i am still within the limit.
