How to remove UnknownFile (Virus Removal Guide)

An advertisement-supported program named UnknownFile (Unknown File) was recently brought to our attention. We were asked “What is UnknownFile?” To answer that question, UnknownFile is desstructive adware. It accesses user browsing data and generates targeted advertisements across Chrome, Firefox, Internet Explorer, and Safari that it feels the internet user is most likely to click on based off of their past and current browsing activities. Advertisements displayed by UnknownFile will often contain text that says “Ads by UnknownFile” on them.

If you see ads by UnknownFile while browsing the web, your computer is infected with adware. But that’s not all. This adware is also known to cause and relate to other serious issues and raises many threatening concerns because it can arrive on a computer system alongside more severe malware.

The ‘UnknownFile virus’ is intrusive because it injects the webpages internet users visit with targeted advertisements in the form of banners, pop-under webpages, and underlined in-text hyper link ads. Sometimes this adware will generate sponsored search results and suggestions. Unwanted targeted advertisements are a serious concern because in order to create ‘targeted’ advertisements and sponsored search results UnknownFile adware will need to access and gather user browsing data and modify current browser settings. Information this adware observes includes all data on the websites you visit and all browsing activities, such as information submitted into online forms (online searches, email addresses, telephone numbers, etc.), bookmarks, and browser history. This information together will allow the adware and programs that it bundles with to generate advertisements that target internet users based off their current and past online habits.

UnknownFile adware also bundles with other unwanted programs, browser extensions, malware, and malicious threats. This adware and the programs that it bundles with schedule new tasks and change existing system start-up settings in order to run every time Windows starts and remain enabled. Programs and browser attachments that may arrive with this adware infection can also cause additional issues for computer and internet users not relating to pop-up advertisements.

Even though the UnknownFile virus is not technically defined as a computer virus or malicious parasite, the unwanted program is still a threat or the sign of a very severe computer infection. Since UnknownFile is known to download and install alongside third-party malware, malicious files, and additional potentially unwanted programs (PUPs), including browser hijackers like Jogostempo.com, it will be necessary to uninstall multiple programs and remove multiple browser objects in order to stop all unwanted activities caused by this program and others from occurring. Apart from manually eradicating the program and others that it bundles with, files may remain undetected to the average computer user. That is why the professional internet security community recommends to use a reputable anti-malware product to remove UnknownFile and malicious files that it may bundle with.

How did UnknownFile get on my computer?

UnknownFile and the unwanted programs that it bundles with are usually always contracted without the consent or knowledge of the computer user. The adware is used to promote free downloadable content from a variety of locations on the web; therefor it bundles with multiple objects. Free downloadable content that this adware may bundle with includes freeware, shareware, torrents, and more.

Users who wish to consciously and manually install freeware may be given the opportunity to accept or decline an offer to install UnknownFile adware and other objects alongside the freeware during the installation and setup process; However, the user request to decline the adware from installing is often ignored by the program or presented in a deceptive manner and the adware will install anyways.

This program and objects that it bundles with can also be promoted and contracted through questionable advertisements. These advertisements are usually dishonest, misleading, and can cause the program to automatically download and install once they’re clicked on.
