Canopus ads. How to remove? (Uninstall guide)

Popups labeled as “Ads by Canopus” or “Brought by Canopus” should not be ignored. Such and similar notifications are a clear sign that you computer is infected with an adware-type program, namely Canopus. It means that you are involved in the vicious circle of advertising, what means that you will be informed about various deals, discounts, coupons, promo codes, price comparisons, and similar commercials whenever trying to browse the net. So, naturally, the question ‘What should I do then?’ arrises. First of all, we want to introduce briefly Canopus adware and then present what solutions do you have to get rid of it.

Canopus adware. What is it and how does it spread?

Canopus is technically a browser add-on. It supports Google Chrome, Mozilla Firefox, Internet Explorer, and Safari web browsers. Its developers present it as a ‘shopping assistant’ and claim that it’s capable of saving users’ time and money while they are shopping online. Unfortunately, but recent malware studies towards this add-on have revealed that these promises are empty. The sole purpose of Canopus adware is to involve people into affiliate marketing and generate its developers income from advertising. Therefore, if each of your web browsers has already started generating pop-up ads by Canopus, our recommendation would be to check the system with Reimage. Why?

Canopus has been labeled as ‘adware’ and PUP (potentially unwanted program). Such classification has been predetermined due to several key factors; these are:

Ads by Canopus

  1. Distribution method. Canopus usually spread by ‘bundling,’ In other words. Usually it is attached to various freewares/sharewares as an ‘optional download.’ In most of the cases, people do not notice it. So, keeping in mind that such third-party components (add-ons, plug-ins, toolbars, extensions) are always set by default, Canopus virus, and its counterparts can land on the system and initiate unwanted activities without being recognized.
  2. Canopus ads. Although it usually gets into the system without being noticed, when the time passes by, it becomes impossible not to understand the presence of adware. That’s because such and similar programs are set to display pop-up ads, banner ads, in-text links, interstitials, and other forms of commercial and non-commercial advertisements each of which is embedded with the links to predetermined domains. Such ads may be very intrusive, so we doubt if you will endure them for a long time.
  3. Canopus redirects to predetermined websites, which is why we DO NOT recommend interfering with any of its ads. This ad-supported extension is supported by third parties, what means that you can be rerouted to various websites. Unfortunately, but the malware studies have revealed that most frequently adware programs promote questionable services, software, online shops, and so on. In the worst case scenario, Canopus add-on can redirect you to malicious websites and make you install another PUP or even virus.
  4. Information loss. Not to mention, the longer you keep this app installed, the more chances there are to lose some personally non-identifiable information. Once installed, this adware activates tracking cookies and transmit information about your browsing habits (search terms, websites visited, clicks, IP address, PC’s location, email address, software/hardware information, etc.) to affiliate parties.

These are the main factors that allowed security vendors to decide whether to classify Canopus add-on as adware or not. Most probably after hearing all the downsides that this app has, you don’t want to keep it installed.

How can I get rid of Canopus virus?

Canopus spreads via software packages. Thus, to prevent such and similar PUPs on your machine, it’s a must to monitor the installation of each freeware and untick check boxes saying that you agree to install unfamiliar tools. If this adware has already ended up on your web browser, you should try to remove it until it starts sending information about you to third parties and until its ads make you install another unwanted app. Do you wonder how can it be removed? Canopus removal can be performed both manually and automatically, so chose the method that you prefer and perform all the steps in the right order.

You can remove Canopus automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.

  • Canopus silly name!!

    It wont let me uninstall and looks like something pooped out of the early 2000s. DO NOT INSTALL for your sake. It keeps showing fake-looking ads and redirects to unknown site. I figured it out!! to uninstall it from google, go to settings and disable extension.

  • Jilly1

    I would not agree that its enough to disable extensions to remove Canopus virus. I did that thousands of times but as soon as I reopen google, this silly app shows up again and again. Mots probably this virus acts differently in all the cases. be careful people since it can make browsing as hell!

  • Lexie Underwood

    sadly I read the reviews too late. But thanks for the help. It seems that Canopus ads are gone now.

  • Robin Castle

    worse than awful! Displays ads and slows the computer. Nothing positive about Canopus. Genuine adware, really.
