What is Program:Win32/Contebrew.A!ml
Program:Win32/Contebrew.A!ml is a detection name used by Windows Defender when detecting infections like adware. According to users, Windows Defender continuously detects Program:Win32/Contebrew.A!ml but does not appear to delete it. Neverending notifications about a detection can get quite irritating, especially when it’s not clear whether the infection is actually still present or not.
Adware infections are not generally considered to be malicious because they do not directly harm computers. They mainly focus on exposing users to as much advertisement content as possible. That mostly involves spamming intrusive ads and triggering redirects. This is very noticeable behavior, so while annoying, users will at least notice that something’s wrong. And it’s worth mentioning that even if adware isn’t directly harmful, the same cannot be said about its ads.
You should avoid interacting with adware-generated ads because you could be exposed to malicious content and/or scams. Adware could show you ads prompting you to download/install some program, or you may be invited to participate in a supposed giveaway. You may also be shown fake alerts claiming that there’s some kind of virus on your computer that requires immediate attention. These kinds of alerts usually either promote questionable/outright malicious programs or want you to call fake tech support numbers so you could get scammed out of hundreds of dollars. These types of scams are generally known as tech support scams.
One more thing about adware that’s worth mentioning is that they track browsing and collect data. To be more specific, the adware will track what sites you visit, what you search for, what content you interact with, your IP address, etc. This information can also be shared with unknown third parties. Considering that adware causes nothing but issues, there’s no reason to put up with any kind of data collection. Especially from a program you likely did not install knowingly.
We will discuss this in more detail in the following section of the report but if you’re wondering how an adware infection managed to install onto your computer, it likely happened via software bundling. The adware could have been attached to a program you installed, and you did not notice. This happens all the time, which is why it’s important that you learn how to install free programs correctly.
If you’re having issues with Windows Defender constantly detecting Program:Win32/Contebrew.A!ml but not fully removing it, refer to the last section of this report. You should first scan your computer with another anti-virus program, and if nothing is detected, you’ll need to fix the issue in Windows Defender.
How do potentially unwanted programs install?
Potentially unwanted programs (PUPs) can be installed without users’ explicit permission. It happens via a method known as software bundling. The way software bundling works is infections like adware, browser hijackers, and potentially unwanted programs can be attached to other programs as extra offers. This allows them to install alongside the programs automatically when users are installing them. Technically, the offers are optional but they need to be manually deselected to prevent their installations. Since the offers are hidden during initial installation, users have a hard time deselecting them.
To be able to deselect the offers, you need to first make them visible. To do that, you need to opt for Advanced (Custom) settings when given the option. The installation window will recommend using Default settings but if you follow this advice, all added offers will be hidden and allowed to install alongside. If you opt for Advanced settings, all offers will be made visible, and you will be given the option to deselect all of them. Some of the offers may seem useful at first sight, but allowing them to install is not a good idea. They will only take up space on your device and cause many issues. Software bundling is a rather controversial installation method for obvious reasons so any program that uses it should not be permitted to install. In fact, anti-virus programs often detect such programs as potential threats. It’s much easier to uncheck a couple of boxes than it is to remove threats like adware, browser hijackers, and PUPs.
In some cases, users are tricked into installing potentially unwanted programs themselves. They may be disguised to look like useful programs. It’s common to find such deceptive programs promoted on third-party download websites. This is why it’s important to research programs before installing them. A simple search with a search engine like Google can often be enough to reveal whether a program/extension is safe to download and install.
How to remove Program:Win32/Contebrew.A!ml
Whenever an anti-virus program continuously detected the same threat but cannot delete it for some reason, you need to use a different anti-virus program to scan your computer for threats. If there’s actually an infection on your computer, other security programs would pick up on it as well. However, if Windows Defender is constantly detecting something as Program:Win32/Contebrew.A!ml but other anti-virus programs do not detect anything, the potential threat has likely already been deleted.
This can happen if Windows Defender blocks the potentially unwanted program but leaves it in Protection History. This would cause Windows Defender to pick up the infection over and over again. Fortunately, it’s not difficult to fix this issue. You can find the problematic file in C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service. In the “Service” folder, delete “Detection History”. If you cannot see the ProgramData folder, you need to make hidden items visible first. To do that, open File Explorer, click on the “View” tab, and check the box that says “Hidden Items”. Once you delete “Detection History”, Windows Defender should no longer detect Program:Win32/Contebrew.A!ml.
