Hello, I´m thinking in trying Returnil free, and i´ve a few doubts: 1 - Is it possible to set permanent exclusions (folders, files, etc)? 2- Can the free version be installed without the AV module? (or can this be disabled?) 3 - Is possible to set a exclusion to windows update? 4 - Is it compatible with Windows 7 x64? 5 - Using Returnil (without av) instead of a traditional resident signature based AV will increase system performance? (i know that one doesn´t substitute the other, and that a multilayered defense is the best approach, but i´m mainly interested in performance here) 6 - Can Returnil be used together with Sandboxie? Any known problem? Thanks!
