I worked on Toshiba SYU3778U0001 Desktop PC. I installed Acrobat reader and other text editors. I want to block that editor so that no can open my documents and made changes into that. These application should be accessible by only me. It is possible that one can open that file and made changes using test editor and save it. To prevent that I want a software which can block these application. Suggest any software or freeware that provide this feature.
