PacFunction is a browser add-on which you can find on your web browsers after installing bundled software. Our malware researchers have found out that the extension could be installed silently after acquiring the infamous TornTV from This version of the application is published by Install Lab ltd., and we do not recommend trusting it. In fact, you should not trust any application which can download unfamiliar software onto your PC without your consent. If you continue reading the report prepared by virtual security researchers, you will learn more about PacFunction removal and the activity of the plugin.

There is no doubt that PacFunction was installed onto your PC alongside other software, whether it was done with your knowledge or illegally, because the official download page is not active. The same has been discovered when researching Crimsolite, Laflurla, Mega Browse, and other widely spread browser applications. Just like these programs, PacFunction can be installed onto Mozilla Firefox, Google Chrome and Internet Explorer browsers, and the removal of the extension is performed via the Control Panel. Unfortunately, not all computer users realize that certain registry keys and files, including Au_.exe, could remain running on your personal computer.

If you do not delete PacFunction from the browsers or if you fail to remove its components, your browsers could be flooded with irritating online advertisements and suspicious pop-up offers. Various pop-up deals, coupons and advertisements are part of the application. In fact, even in the Support section found on the official web page it is indicated that the application uses online advertising to enhance your browsing sessions. In order to understand this activity you need to check the Privacy Policy. Here you will find that the plugin is affiliated to third parties who may be responsible for serving all the pop-ups, banner and in-line ads.

As mentioned before, in order to delete PacFunction from the system successfully, you need to remove the plugin and the components related to it. Not many Windows users are experienced enough to perform this task on their own, which is why automatic malware removal software is the best solution in this case. Even if you succeed with the manual PacFunction removal, we still recommend installing automatic malware detection and removal software to guard your PC and delete other threats which may have been installed onto the computer silently as well.
