What struck me as odd is that the notification shown in the next screenshot did not show up every time I installed this bundle. In fact I had to try a few times before I saw it. We can’t be sure if this is intentional or a flaw in the bundler.
A very important sentence in that notification is the reason why this is considered spyware by some and just adware by others.
We make commercially viable efforts to automatically filter confidential personally identifiable information and to purge our databases of such information about our panelists when inadvertently collected.Now, if I were a less trusting person I could read that as “we try to remove the really confidential stuff if you signed up voluntarily.” For sure it should leave you wondering what they consider:
- viable efforts: is there an acceptable standard for this and are they in compliance?
- confidential personally identifiable: is not everything that is personally identifiable considered confidential, and if so what exactly isn’t?
- panelists: does this include the people that get the software in a bundle?
BundleLooking at the installation of such a bundle we used Scrollup – adware in its own right - as an example. As you can see below you are given the opportunity not to include RelevantKnowledge.
During install you can "Accept" or "Decline" RelevantKnowledgeAll the changes made by that installer can be found in the logs that are included in our removal guide on the forums. Most notably the RelevantKnowledge service that will be set to run automatically. This means that this service will always be running in the background unless the user does something about it. The file can usually be found at “C:\Program Files (x86)\RelevantKnowledge\rlservice.exe”
Another notable fact is that the bundle installer downloads a file called PackageV.exe from post[dot]securestudies[dot]com before it offers the option to include RelevantKnowledge. This file used to be called rkverify.exe so your guess that it serves to check whether RelevantKnowledge is already installed is probably the same as mine.
Detection and ProtectionMalwarebytes Anti-Malware Premium protects you against Scrollup and RelevantKnowledge getting installed. our forums.
SummaryRelevant Knowledge is adware that comes bundled with many freeware utilities. But there are claims that it is spyware as well. We tried to show you some reasons for those suspicions.
