Comodo forums cannot help I installed an image editor program on 64 bit win 7 desktop and ran it . It said it was isolated or restricted. i clicked do not isolate it again. It was isolated again. Now it will not run even if i disable comodo I cannot add it to trusted files. I do as I should it does not happen It is not in blocked files It was in or i put it in hips rules. Would not run under any setting. Cannot remember all I tried Cannotv add vendor to trusted vendor it is not signed. It is legit program though Not sure how but i managed to remove it from unrecognised files and tried again. Now it is sandboxed as fully virtualised but does not appear under advanced\defense\ sandbox Is there anywhere in registry blocked files can be cleared?
