Polymorphism in Google Drive and Google Chrome (wrt Handling an Exe File)

Important Note: We are not trying to arrive at a very concrete conclusion or result here. The testing was done to identify the behavior of 'Google Drive' and 'Google Chrome' when 'Google Drive' thinks a file could be a virus.

User1: This user is the original author of the file and has shared the folder with User2.

1 - incognito, no-user, two virus alerts



2 - incognito, no user - A virus was detected you can't download this file (gmat2.zip)



3 - incognito, User2, virus detected, can't download



4 - incognito, User2, polymorphism, cannot delete file in shared folder from other person



5 - normal view, User1, file with virus alert can still be downloaded from original author's account



6 - incognito, User2, different type of alert for an exe file that gdrive says could be virus but did not alert before



7 - incognito, User2, can't download file, enable third-party cookies for GDrive



8 - normal view, User1, original author can remove a file from folder shared by him



9 - inconito firefox, User2, potentially infected exe file not downloadable from incognito chrome is allowed to be downloaded here



10 - a view of gdrive trash of original author User1 with removed files



11 - incognito, User2, you do not get remove rights on a file but you do get remove rights on the entire directory shared with you



12 - Incognito chrome, User2, Still cannot download the suspected folder, asks to enable third party cookies
