Is PUADIManager:Win32/OfferCore dangerous?

I have already stated that PUADIManager:Win32/OfferCore is a detection that stands for a bundling module hidden within an installer. Such applications are exremely common in schemes that spread unwanted programs. But that is not a sole danger of Win32/OfferCore, as the function of side installation may be useful for malignant purposes.

Dangers of PUA:Win32/OfferCore

  • Installation of unwanted programs without your concent;
  • Potential modifications to the system settings;
  • Confusing users by telling it is mandatory to install bundled apps;
  • Acting as a downloader for full-fledged malware, particularly backdoors and spyware.

The very fact of using software bundling should put in unfavor the program you’re trying to install. There are plenty of other methods of monetizing the job of developers, and standing on a slippery slope together with malware is quite a poor option. I recommend you to search for another, clean installation of the app, once you see the OfferCore detection.

How did I get this virus?

Obviously, OfferCore is a key part of a software bundling mechanism. Hence, it is typical to see this junk app inside of programs downloaded from the web. In particular, it often appears inside of the installers for free software and cracked programs. Every single program installed as a side to the main app pays to the developer of the “main” software in this bundle.

Less evil of bundled installation – free (and unwanted) antivirus. You can get much more serious things in such a pack.

Freeware developers often only a few options to monetize their job, rather than using software bundling. However, they rarely use unswitchable bundlers, like OfferCore is. Such a gnarly approach mostly appear in cracked apps that you get from warez sites or torrent seeds. Users who spread such stuff are breaking the law already, so they have nothing to lose.
