Opera Stable

If you have suddenly found a new program called and you are wondering what is opera Stable? What is Opera stable doing on your PC, how it got there and what exactly does it do.

What is Opera stable?

The Opera browser is a perfectly legitimate internet browser developed by a company named OperaSoftware ASA and Opera Stable is the latest stable release of this browser. There is nothing malicious with the Opera browser. However the installation of Opera stable you have on your computer may or may not be legitimate.

The Opera Stable process

Opera is less popular than its three major competitors in the browser scene – Chrome, Mozilla and Internet Explorer. To counteract that, Opera is often distributed as part of software bundles, through 3rd party programs and this leaves room for abuse from unscrupolous hackers.

The fact that Opera stable was installed without your explicit permission or knowledge is worrying enough to raise the question what is Opera stable. It could be the real thing, or it could be an injected, modified .exe of the original program that works as a rootkit giving access to other, more dangerous viruses. It is also very likely that other programs were installed alongside Opera stable – likely Adware or Spyware.

Regardless of the cause you should probably remove it

The thing with these randomly acquired programs is that you never know where the catch is until it is too late. If you want to test if the Opera browser is to your liking you should delete this copy and download the program from the official program developer. This way you will know for certain that the executable has not been tampered with.

If you have already tried to use the copy of Opera stable that is on your computer and you received search results from strange search engines then you should immediately remove it. (Opera default is Google, everything else means it’s a fake). It is also possible that you are subjected to a much larger then normal amount of Advertisements while you browse – again this means you are running an Adware program designed to look as Opera. It is even possible that Opera stable is just a virus masquarading under the name of known and trusted software.

  • If you already tried to remove Opera stable through the control panel and it didn’t work or parts of it still remain then you are absolutely dealing with a virus. You will find the instructions how to remove the virus further below.
  • In conclusion we’d like to say it is hard to determine what is Opera stable for sure until we test the particular sample that you have installed on your machine. The most prudent course of action is to remove it immediately and then re-download it from the official Opera site if you are curious and looking for a browser alternative.
  • Finally try to remember what caused Opera stable to appear in your computer. The most likely culprit is probably a program you have recently installed and that program is possibly infected with a virus. After you deal with Opera browser you will have to adress the program that installed it as well. Keep on reading.
