Windows 7 bug + virtual box bug

Latest comodo antivirus + firewall is not working with fresh installed windows 7 x64 (activated), after comodo installing it doesnt do anything or tell me to restart computer, even after restarting comodo is not opening at all.

Second bug is with virtual box, i have fresh windows 8.1 x64 installed and when i run comodo dragon in virtual mode and download some file from internet, the file goes in downloads folder and when i go in normal mode (outside the virtual mode) i can see the file i downloaded in virtual mode, this should not happen when i download files in virtual mode, i can also edit/delete files in virtual mode and the files disappear from normal mode as well.
