The “Flash Player Auto Update Daemon” Pop up

If every time you open Chrome, Safari or Firefox (or another browser that you have on your computer) the screen of the computer gets flooded with irritating advertising materials, then you may have an undesirable application inside the browser that is causing the over-generation of ads as well as other potential annoying effects. Normally, the applications that could be responsible for this type of ads irritation belong to the adware or to the browser hijacker software categories. The representatives of both of these software families are similar to regular browser extensions and both are known for spamming the user with massive amounts of advertising content and page-redirects. The main difference between hijackers and adware, however, is that the hijackers may also introduce certain modifications to different elements of the browser. For example, if you seem to now have a new search engine in your browser or a new homepage, then you likely have a browser hijacker on your hands. Normally, the changes that such an app may introduce to the browser would happen automatically, without the direct and informed permission of the user. This can be quite irritating and some users may even mistake such changes in the browser for the activity of some insidious malware piece. However, if the symptoms mentioned above are the only issues you are currently faced with, the good news is that you are indeed dealing with a hijacker and not a Trojan, a Worm or some insidious Ransomware infection. In case you need help with the uninstallation of this application, you can rely on us. The guide that will be presented to you next has all you will need to quickly remove the undesirable “Flash Player Auto Update Daemon” application.
