Ads, ads, ads…they are all over your screen and you tear your hair in frustration to close them down but a new flow of pop-ups appears instead. It is unbelievable how irritating an ads-generating program like Archer.dll could be and the amount of online disturbance it can bring could really make you give up on all the technology progress and never open your browser again. However, there is no need to go back in the cave to save yourself from the ads because on this page you are going to learn how to remove this annoying program by yourself. Yes! With the instructions in the removal guide below, you can detect and manually delete the respective files once and for all! And if you want to make sure you never get any closer to adware of this type again, we suggest you read the next lines, where you will find our effective prevention tips and protection solutions.

Why would anyone create such an annoying piece of software?

Probably this is the question that is in your head while you are trying to unsuccessfully close all the banners, pop-ups, new tabs and boxes that constantly jump on your screen. Well, like any other software, adware also has its purpose. It is created with the idea of displaying dozens of advertising messages and collecting as many clicks as possible. The goal of this seemingly useless activity is, of course, money. This is the goal of the Archer.dll creators as well. Through a Pay-Per-Click (PPC) scheme, all the clicks that the displayed ads collect are turned into income for the adware developers. That’s why they have programmed this application to aggressively bombard users with numerous flashy banners, popping boxes, links, and messages. It could even redirect the searches to some other promotional pages instead of the desired directories, just to increase the chance of users clicking on some ads. You will probably be surprised by the number of businesses that take advantage of this PPC scheme as well as the many programmers who use it to sponsor their free software releases.

Where the problem occurs? Is Archer.dll an actual computer virus?

No, not really. But there is a caveat to such a statement. While there is nothing wrong when people make money out of ads, the problem appears when they overdo it with the amount of the displayed messages and create a rather unpleasant disturbance to the users. This may happen when some undesired changes and activities, implemented by the adware, take place. For example, you have probably noticed that apart from the aggressive way the ads are delivered to you, the homepage of your browser may also be changed. A strange add-on may have changed your default search engine and every time you browse the web, your searches get redirected to some other web locations than the ones you type in. This activity may eventually expose you to some risks if you happen to land on unsafe web locations or compromised content. Malware threats like viruses, Trojans or Ransomware usually hide in such places and bumping into them unknowingly is a possibility you can’t predict. Moreover, hiding harmful payloads in ads (a method known as malvertising) is a common method used by the cyberciminals to spread malware, especially the Ransomware type, which is recently increasing in popularity.

Please don’t think, however, that the indirect risk of bumping into malware means that adware such as Archer.dll is a malicious application itself. It may be often wrongly called a virus, but the ways and means such programs operate have nothing identical with viruses, which are forms of cybercrime. In fact, as annoying as it could be, Archer.dll is a legal program and it generally serves the needs of the online advertising industry. At its worst, it may keep track of your online activity and collect browser-related information like the pages you visit, the products you search for, etc. Based on that, the adware would try to display ads, relevant to your interests in hopes that you’ll click on them more. But it cannot steal your data, corrupt your system or spread infections into multiple computers like the viruses do.

Prevention and protection tips.

In case you feel really disturbed by the activities of Archer.dll, below you will find the exact instructions on how to remove it. Once you are done, you may wish to effectively protect your system from getting adware-like applications again. To do so, you should always pay attention to what programs you are installing on your computer and most importantly, what other software you have in the bundle you are installing. This could be checked through the advanced/custom option in the setup. Usually, adware could be found there, especially if the software you are installing is free. If you stay away from spam emails, open source download platforms, direct downloads or torrents, you will decrease the chances of getting not only adware, but also some other types of more serious threats. But don’t rely only on that and install reputable anti-malware and antivirus software to ensure optimal protection of your system.
