Tabulation Spreadsheet

What is Tabulation Spreadsheet?

Identified as a version of the CMI/ConvertAd family of malware ad-injectors, this adware which is typically bundled with third-party applications in unwanted software bundles will hijack the user's browser (Internet Explorer, Chrome and Firefox) and display unwanted ads. When running, the process will monitor and capture internet traffic and insert advertisements over existing ads or by placing new ads in white space. In either case, these ads are low in quality and even dangerous in many cases as they might be infected with malware javascript (malvertising). In addition to displaying these unwanted ads, the software runs as startup in the local application data via a registry run key and sends commands to the controlling server to request new ads based on the context of what the user is doing. This action will also report back to the server what domains the user visits, what URLs they enter as well as in some cases might send back cookies. If the sites visited are not SSL encrypted passwords and usernames might be sent to the server compromising the privacy and security of the user.


During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. The primary executable is named bnsaa121.exe. A majority of users end up uninstalling this less than a week of it being installed.
