Adware threats use a variety of methods to infect computers, but what is similar between all of them is that they target the human behind the device and try to make him install the virus himself. This way all anti-virus and anti-malware defenses are bypassed, because the User has the final authority. Of course people never willingly install a virus themselves, so Ads by Eridanus used deception. The virus came in the form of an executable file and under one of the following guises:

  • As part of a software bundle – when you install software the installer may try to install more then the main program. Use Advanced installation to be able to see and control what exactly will get installed.
  • Via an email attachment – don’t even open those unless you are absolutely certain they are not a virus
  • Through an online Ad scam – much like the Ads generated by Ads by Eridanus Ads on dangerous sites will try to install different malware on your computer. Don’t trust them – only install programs manually downloaded by yourself from the main site
  • Through a fake download link for a program update – again only install program updates you downloaded yourself from the official source
  • Posing as a missing plug-in or codec you need to install in order to see online media – unless your computer has been freshly formatted you should never see these. More often then not it’s a scam
