Ads by Canopus

Ads by Canopus is a program you probably don’t want on your computer – it is a type of virus called Adware. In its core it will create advertisements, which can track the sites you visit and then try to sell you things from there. If you think this is a suspicious and disturbing behavior then you are right on your money.

Ads by Canopus can not be turned off and it will continue to spam Ads until the moment it’s removed from your system. The Ads it creates could be in under any of the following formats:

  • Pop-up windows, sometimes even big enough to cover the screen.
  • Banners – often multiple of them.
  • New pages filled with pop-ups and banners.
  • Turn words of any text you read into hyperlinks.

Dangers associated with Ads by Canopus

First of all Ads by Canopus slows down your computer. Whenever you try to load an internet page your CPU also has to load an Ad, which means double the work. It also has to download the information needed to display the Ad, which means extra bandiwidth and maybe even severe slowdown if your internet speed is not that great.

Next the Ads themselves can try a possible phishing scan on you. The idea here is to point you to an online shop that looks exactly like a well known and respected site like Amazon. When you try to purchase anything you’ll have to deposit credit card numbers and passwords, which are recorded and then your accounts emptied.

Lastly Ads by Canopus can also try to install other viruses through it’s Ads. They will of course be hidden under the guide of free software installations. Ads by Canopus can also generate fake messages about non-existent issues with your PC – things like missing plug-ins, codecs, viruses or errors in windows or the registry records.


Now we will begin the removal process itself, but before we start there is one thing you should know beforehand. In order to make viruses harder to remove their creators keep tweaking and improving them even after they are released. The end result is that the same virus can exist in multiple versions at the same time. The later iterations are generally harder to remove and require more operations to do so, but their functionality largely remains the same.

This is also the case with Ads by Canopus. We’ve written the guide such as to be able to remove all versions of this malware, but this also means parts of it could be redundant if you have been infected by an older version of Ads by Canopus. Run carefully each step and if at any point you don’t see traces of the virus don’t worry and simply proceed with the next step.
