How to uninstall Orange Defender Antivirus software
Written by Tomas Meskauskas on (updated)
What is Orange Defender Antivirus?
As its name suggests, Orange Defender Antivirus is software that detects and eliminates computer viruses and other threats. In fact, this computer security program is distributed through the 'installers' of other programs. I.e., it is included into the set-ups as "additional offers".
Programs that are distributed in this way are categorized as potentially unwanted applications (PUAs) and are generally untrusted.
Orange Defender Antivirus is not a free security suite - users must activate (purchase) it after a 30-day free trial. PUAs are often designed generate a fake scan result list, which 'detects' fake issues.
The main purpose of these apps is to trick people into believing that their systems are infected with viruses, contain errors, and other problems, and then encourage them to purchase software to supposedly fix the issues. It is currently unconfirmed whether Orange Defender Antivirus is one of these rogue PUAs, but it is a strong possibility.
As mentioned, this program is distributed through the set-ups of other programs. Note that set-ups are commonly used to distribute multiple PUAs at once. Therefore, Orange Defender Antivirus might be distributed together with browser hijackers and/or adware-type applications.
Browser hijackers promote the addresses of fake search engines by changing certain browser settings. Many gather information relating to users' browsing activities. They usually target browsing-related data such as geolocations, entered search queries, addresses of visited pages, IP addresses, and other browsing data.
Gathered data can be sold to third parties (potentially, cyber criminals) who misuse it to generate revenue in other ways. Note that some browser hijackers record personal, sensitive details as well. Adware is rogue software that serves advertisements. For example, coupons, banners, surveys, pop-ups, and other ads.
People who click these advertisements allow them to open untrusted websites. In some cases, thee ads cause download/installation of PUAs by executing certain scripts. Therefore, remove all PUAs from your system immediately.

| Threat Type | PUP (potentially unwanted program), PUA (potentially unwanted application). |
| Supposed Functionality | Orange Defender Antivirus is advertised as computer security software. |
| Detection Names | Avast (FileRepMalware [PUP]), BitDefender (Application.Deceptor.APC), ESET-NOD32 (A Variant Of Win32/InnovativeSolutions.C Potentially Unwanted), Kaspersky (Not-a-virus:Downloader.Win32.OrangeDev.a), Full List Of Detections (VirusTotal) |

Some examples of programs also categorized as PUAs are ScanMyReg, Tuneup Pro and SpeedyFixer. Commonly, such PUAs are advertised as tools designed to fix errors, detect and remove malware, etc., however, few are legitimate or function as advertised.
PUAs often deliver no value and simply function to generate revenue for the developers. Therefore, never download or install apps of this type.
How did potentially unwanted applications install on my computer?
Commonly, various potentially unwanted apps are downloaded and/or installed through the set-ups of other programs. I.e., when they are included in download/installation set-ups as 'additional offers'. Usually, these offers can be found settings such as "Custom", "Advanced", "Manual", etc.
When people download and install programs without changing the default settings, they inadvertently allow PUAs to infiltrate. This distribution method is called "bundling". Additionally, unwanted downloads and installations can be caused by clicking deceptive advertisements that execute certain scripts.
How to avoid installation of potentially unwanted applications
Third party downloaders, installers, unofficial websites, Peer-to-Peer networks (torrent clients, eMule), and other similar channels and tools are often monetized by promoting unwanted applications. Therefore, files and programs should be downloaded only from official pages and via direct links.
Unwanted downloads and installations can be prevented by declining offers to download or install PUAs, before completing the process. Generally, these offers can be declined by changing the "Custom", "Advanced", "Manual" and other settings. Intrusive ads that appear on dubious web pages can open other websites of this kind or download/install unwanted software.
For these reasons, never click these ads. Remove any suspicious, unwanted extensions, plug-ins and add-ons already installed on the browser immediately. The same should be applied to programs of this kind that are installed on the operating system.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
