Online.io is a rogue application that infiltrates the system without permission and manifests strange behavior

Online.io adware

Online.io virus is a traffic exchange software or adware that injects webpages you visit with tons of commercial content. Those advertisements display content that promotes other software and often has Ads by Online.io on the pop-up or banner. This is the first indication that your machine is at risk or already has a PUP infection. This intruder continuously monitors your Internet browsing activity from the first minute of cyber infiltration. Since this is the ad-supported site it gathers such data for the later malvertising use.

Unfortunately, this potentially unwanted program even is associated with technical support scams, in particular, Microsoft Security Essentials Alert. The adware Online.io displays these fake alerts about security issues and pretends to offer a solution for the error. The message also tricks people into calling the fake technical support via the phone number that redirects the victims to criminals and scammers instead.

Online.io adware functions as a shady website[1] with the sign-up form. Even though there is a punchline “Ethic change with technology,” the website does not indicate any privacy policy nor terms of use – obligatory elements of a reliable site. It has been on the web already since last year. Despite its promise “coming soon,” there was no change. Since then it has been labeled as adware.

However, due to its odd behavior, virus researchers suspect it might be related to a tech support scam. You might be redirected a browser-based scam site which alarms you with supposedly infected system. In order to remove the virus, you may be asked to call +1-888-496-5150 or alternative number. Exit the window and clean the browser from its web scripts.

Other than the scam message there is nothing wrong with your machine and the fake alert only focuses on tricking you into revealing personal information, paying for suspicious service or visiting a more questionable site that promotes shady software.

Users also complain about additional issues regarding this PUP:

  • redirects to shady pages;
  • advertisements injected on commonly found pages;
  • suspicious processes running in the background;
  • installed programs and tools.

The functions of Online.io adware

It seems that the owners of this website are still preparing to launch the official website. If you enter it, you see the front page saying that the domain is not active yet and, in the case of inquiry, you can enter your contact information. In addition, the web page is protected by certain technology to evade spam emails.

Though this quality might suggest the reliability of the web page, the adware still successfully operates in a background. Since it travels in sneaky ways, you might not suspect that the PUP resides on the operating system. 

Nonetheless, you might consider excessive advertising as the sign of the adware. The pop-ups contain almost invisible “Online.io ads” labeling[3]. You might notice enormous entity of ads varying from banners of suggesting to install new security applications to commercial offers recommending the newest game.

If you are not careful and click on those ads you might be misled to the websites not only with advertising content but to the domains which might be infected with high-level viruses [4]. In this manner, online.io redirect tendency might even bring damaging effects.

In addition, we would like to encourage you to restrain from downloading any applications or updating the software from the domains promoted by the adware. Before your PC performance deteriorates, remove Online.io virus. You can do it faster with automatic antivirus tools.

Adware distribution tendencies

Often, the adware exploits the chance to infiltrate the system when users install other free programs. There is a common tendency to rush through the installation instructions and click “Next’ without the awareness of other possible programs.

Likewise, you will be able to detect all unnecessary applications. When you make sure that none suspicious programs sneak into the OS, install the wanted software. Such cautiousness will help you escape the hijack of other PUPs in the future [5].
