File Opener Pro is a potentially unwanted program that injects browsers with intrusive ads

File Opener Pro
File Opener Pro is a potentially unwanted application that is usually spread via software bundles

File Opener Pro is an application that users might find on their computers after the installation of freeware or shareware apps from third-party websites, although some might be keen to try using it because of its functionality. As stated by developers Choice Install, the app works perfectly for opening various file types, such as MS Office, PDF, audio, video, and text files – all for free. However, users initially don't know that File Opener Pro is an adware[1] app that spams Google Chrome, Mozilla Firefox, Internet Explorer, and other browsers with intrusive ads.

Besides unwanted advertisements, File Opener Pro can also add a browser extension and insert browser helper objects into Internet Explorer in order to display banners, pop-ups, coupons, deals, and other commercial content. Additionally, users' web browsing activities might be tracked with technologies like cookies or web beacons[2] to increase the revenue from targeted ads.

Name File Opener Pro
Type Potentially unwanted program, adware 
Main executable  fileopenerpro.exe
Infiltration  In most cases, users install PUPs like File Opener Pro unintentionally when downloading apps from third-party sites. Additionally, they might also get tricked by an attractive advertisement or a fake update
Main dangers  Installation of other unwanted programs or malware, money loss due to frequently encountered online scams, 
Symptoms Those who get infected might start noticing intrusive ads that are sometimes marked as “Ads by File Opener Pro,” “File Opener Pro ads,” and similar; searches might be filled with sponsored links; browser redirects might frequent users' web browsing sessions, etc.
Termination Either use anti-malware software that has PUP detection feature or apply steps provided in our manual removal guide below 
Recovery & optimization In case your computer still acts sluggish or you experience software crashes, you should scan your machine with PC repair tool Reimage Reimage Cleaner Intego

Those who installed File Opener Pro intentionally might not instantly recognize that the intrusive ads are comping from the program, as it is often not easy to separate the embedded commercial content from the one that is caused by an adware. However, users may also experience sudden redirects to websites that they never intended to visit in the first place.

In many cases, users will find themselves on insecure websites that promote shady scareware[3] apps by showing fake virus alerts or claim that Adobe Flash is out of date. These are typical online scam pages that users infected with File Opener Pro might face. Those who are not familiar with such scams may be tricked by cybercrooks' social engineering skills and download the promoted app (which might as well be malware) or contact malicious actors via the provided phone number.

Therefore, if you are experiencing browser behavior that seems odd, you should remove File Opener Pro virus from your system. Adware might be considered as far as malware by some security researchers, while others might only see it as a nuisance that constantly bugs them. If you belong to the latter category, remember that free apps are usually not free at all, as they are sponsored by advertisements. Indeed, showing ads is not a crime, it is just when users are exposed to insecure online material like online scams it becomes a problem – and File Opener Pro will show you bad ads as well as safe ads regularly.

If you want to keep your machine secure, you should not delay File Opener Pro removal – you can either rely on security software that recognizes potentially unwanted programs or use our manual instructions below. If you also installed software that was promoted via online scams, your machine might also be infected with malware, and anti-virus will take care of that.

Finally, experts[4] recommend resetting all the installed browsers after PUP elimination and scanning the computer with Reimage Reimage Cleaner Intego or similar repair tool if having problems with system slowdowns and crashes post File Opener Pro termination.

Avoiding potentially unwanted programs is easy – here's how

As mentioned above, adware might be categorized as a relatively harmless app that displays ads, as well as software that engages in background activities that can compromise users' online security. In some cases, the adware can also be a part of far more malicious campaigns like botnets or be injected via backdoors. Security experts noticed multiple instances when advertising revenue is being generated by adware programs which were injected via other malware that was previously installed on the system.

Thus, while in most cases, on its own, the adware will not cause such major consequences like identity theft or financial data leak, it might be a sign of much more serious infections. Additionally, software that disrupts online web browsing sessions on a regular basis is no good addition to any home user's computer.

Since the main distribution method of adware is software bundling, these tips should help you to keep PUPs away from your machine:

  • If possible, always choose official download sources instead of third-party ones;
  • Always visit the official website to update software or do it via the app;
  • Before installing app you are not familiar with, check online reviews and blog posts about it;
  • During the installation process, check the installation instructions carefully: unmark all the pre-ticked boxes, read the fine print, watch out for misplaced buttons and deceptive offers;
  • When prompted always pick Advanced/Custom settings, as sometimes it is the only way to uncover optional components and remove them before they are automatically installed.

Additionally, you should always keep a comprehensive security program installed on your device and keep it updated – it might warn you and prevent the installation of unwanted programs, along with malware.

Get rid of File Opener Pro

File Opener Pro removal can be either difficult or easy – it all depends on the system configuration, whether other PUPs/malware is present on the machine, and your computer skills. Note that ads are not necessarily a sign of infection, as they might be simply embedded within sites that you visit. To prevent those, you can use specially designed ad-blocking browser extensions. Nevertheless, if you encounter ads on websites that typically don't serve them or they are marked by “File Opener Pro ads,” you need to take care of the unwanted program installed on your machine.

You can remove File Opener Pro with the help of security software automatically – note that not all anti-malware programs will recognize all PUPs, as it depends on a vendor (each has different criteria for marking program as a “potentially unwanted”). Thus, you could simply employ the instructions we provide below and get rid of the File Opener Pro virus manually. Resetting browsers is also highly recommended, as adware changes their settings without permission, and only a reset could fix that.
