I went to update Flash Player earlier today by downloading the web installer from the website, but by mistake didn't uncheck the option to install McAfee Security Scan Plus with Flash. However, after comparing the two files that are downloaded when the option is/isn't unchecked, I noticed that the MD5/CRC hashes for both files are exactly the same. I opened the file, and noticed that the installer was downloading both Security Scan Plus and Flash. I canceled the installation which was fine, but I have several questions.
How does the installer know if the user wants to install Security Scan if both files are the same?
Is Security Scan installed as soon as the download is complete (as shown in the installer), or only after Flash finisheds downloading as well?
