Office365 “Virus” – How Did I Get It

One of the main way via which programs that cause redirects to web pages, like the Office365 scam is believed to be via software bundling operations. These types of activities often involved third-party programs that are often downloaded by users. Such programs include drivers, media players, downloaders, converters and any other free helper program you can think of. They often come embedded with ad-supported programs and PUPs which are cleverly masked as a seemingly legitimate software that is added to the installers of those programs. One such software may be the one which introduces the Office365 phishing screens on the victim PCs. But it is not easy to detect those programs when you install freeware, since they are often concealed well within the “Advanced” or “Custom” installation modes.

Another method and scenario via which the Office365 may be spread on your computer system is if you have tried to download a document by clicking on a web link and have received the following notification:
