How irritating is this problem? (6 votes, average: 4.33)

This page aims to help you remove Panda Viewer “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Is your browser behaving strangely? Are there tons of annoying ads, pop-ups and banners on your screen, which aggressively interrupt your browsing activity and redirect you to different web locations? This could be a result of the activity of a software application called Panda Viewer. Now, Panda Viewer is a potentially unwanted piece of software from the browser hijacking type, which can affect your Chrome, Firefox, Internet Explorer or any other browser that’s been installed on your PC. Its creators have basically programmed Panda Viewer to generate ads, cause redirects, and track user information with one purpose – online advertising and generation of profits from Pay-Per-Click ads. Many people report that they feel irritated by the activity of this page-redirecting browser hijacker, moreover, they have no idea how it has been installed on their computer. Panda Viewer seems to have no uninstallation option and therefore, the users cannot remove it from their browser and stop the aggressive streaming of ads, pop-ups and banners on their screen. That’s why, most  users consider this hijacker to be a virus, but we want to emphasize that the original Panda Viewer service is legitimate and has nothing to do with malicious infections such as Ransomware, Trojans and other nasty computer viruses. Still, this program may cause browsing irritation and disturbance and for this reason, in the next lines, we will show you how to remove it and save yourself from the ads. Just read the information that follows and use the instructions, shown below.

How may you end up with Panda Viewer on your computer?

Typically, Panda Viewer ads may appear on your screen after an “incorrect” installation of software packages and their bundled components. This usually happens when the users download free programs and install them without carefully customizing the setup configuration. Instead of making sure that all installation settings have been manually customized, most users go for the “Fast” or “Recommended” setup, which often does not reveal information about third-party applications that may be attached to the main program. Unfortunately, the “fast/recommended” installation method is very popular among the computer users and they simply click on it, believing that this is the right way to install the software. However, this method usually makes them agree to the installation of additional software, such as Panda Viewer, without directly disclosing its presence inside the installer. Fortunately, there is an easy and effective way to avoid the installation of unwanted applications – you should simply use “Advanced” or “User” settings every time you run a new setup (especially a free setup pack) and observe have a careful look at the optional clauses displayed there. Once you see checkboxes with pre-marked download components, which you do not want to be installed on your computer, uncheck them and they will not become part of your system.

What may Panda Viewer do?

Panda Viewer is not a dangerous program. It cannot corrupt your system like a Trojan horse or encrypt your data like a Ransomware. However, this browser hijacker can modify Windows Registry and change the settings of all browsers that are installed on the affected computer, including Chrome, Firefox, IE, Opera, Edge, etc. Some of the most obvious changes may include the installation of a new search engine and/or toolbar and replacement of your old homepage. In addition, Panda Viewer may display third-party advertising content on the web pages that you are visiting. These ads may offer you to download security programs, get discount vouchers, and more. However, oftentimes such content could misleading and unreliable. In fact, clicking on the ads generated by Panda Viewer and interacting with the pages it might redirect you to is generally not recommended because some of them may be redirecting you to unfamiliar or insecure web locations. Some of the ads may also be malicious and infect your computer with malware, such as Ransomware, Trojans and other cyber threats. For this reason, we advise you to remove the hijacker as soon as possible.

How to uninstall Panda Viewer?

One way you can remove Panda Viewer is to scan the entire system with the help of a reliable malware-removal tool. Such software is suggested on this page, within the guide below. Once the tool has automatically detected and deleted all suspicious entries, just reset your web browser settings and you will get your browser back to normal. You can also use the instructions in the Removal Guide below and manually find and remove the hijacker-related files. Pick up the method that you feel most comfortable with or use them both (that’s what we’d advise you to do).
