Program:Win32/Contebrew.A!ml Removal Guide
What is Program:Win32/Contebrew.A!ml?
Program:Win32/Contebrew.A!ml is a detection name for a potentially unwanted program that is trying to break into your device
Program:Win32/Contebrew.A!ml is an adware application that you could have downloaded in a bundle from a suspicious website, or you were tricked into believing that it is useful in the first place. The threat is typically identified by Windows Defender, although other security apps can use the same name. It belongs to a potentially unwanted program category, which typically represents changes made to Google Chrome, Mozilla Firefox, MS Edge, Safari, or another web browser.
Thus, if the PUP manages to break in, you might see the homepage and new tab address changes, redirects to suspicious websites, and ads showing up during your web browsing sessions, namely popups, banners, deals, coupons, offers, and other intrusive content.
The problem with this potentially unwanted program is that the threat is persistent, and users said they struggled with Program:Win32/Contebrew.A!ml removal. This typically occurs due to a Windows cache bug that can be cleared and the repeated detection terminated for good – check below how.
| Name | Program:Win32/Contebrew.A!ml |
|---|---|
| Type | Adware, potentially unwanted program |
| Distribution | Software bundles, deceptive ads, fake Flash Player updates, third-party websites |
| Symptoms | Inability to eliminate the potentially unwanted program; unknown browser extension or application installed; intrusive deals, coupons, discounts, offers, and other advertisements; redirects to ad-filled, scam, phishing, and other dangerous websites |
| Dangers | Redirects to malicious websites can result in unwanted site notifications, personal information disclosure to unknown parties, financial losses, installation of other potentially unwanted software or malware |
| Similar | Win32/Bundpil, PUA:Win32/Puwaders.B!ml, VirTool:Win32/DefenderTamperingRestore |
| Elimination | While it is usually easy to uninstall potentially unwanted applications, some threats just don't want to go away – and this is precisely the case. In order to get your security software to stop repeatedly detecting this threat, you need to clear the detection history within Windows Defender folder |
| Further steps | Malware or adware infections can diminish the performance of your computer or cause serious stability issues. Use RestoroIntego to remediate your device and ensure that the virus damage is fixed |
Adware programs are generally not considered malicious, although some security advocates and researchers claim that some adware might compromise user security and open the system to additional infections. Thus, there is a great need to prevent infiltration of such programs, as they also rarely provide any useful functionality to users in the first place.
Once installed, Program:Win32/Contebrew.A!ml virus focus shifts to delivering intrusive ad campaigns, meaning that those infected would see various ads while browsing the web. Homepage, search provider, and other browser changes can also accompany the unwanted behavior.
Redirects might also occur, landing users on websites that advertise useless software, attempt to extort money with phishing techniques, or include malicious JavaScript[1] that would download and install malware automatically under certain circumstances.
It is also important to note that most potentially unwanted programs such as adware collect a variety of information about users' online activities. With the help of cookies, web beacons, and other tracking technologies, the following data is automatically harvested and later used for marketing purposes:
- IP address
- Internet Service Provider
- Approximate location
- Timestamps
- Links clicked and sites visited
- Search queries
- Technical device data
- Installed apps and extensions, etc.
However, if you have your computer equipped with security software such as Windows Defender, it would flag the intrusion as soon as Program:Win32/Contebrew.A!ml would attempt to break in. Unfortunately, users said that the main problem with this detection is that it would not go away and show up regularly, up to a few times a day. They also claimed that they quarantined the threat once it showed up.
There could be a few reasons why this is happening: either there is additional malware installed on the system, Windows Defender can't fully eliminate the PUP or a bug within the Detection history folder. Thus, you should employ different security software, such as SpyHunter 5Combo Cleaner or Malwarebytes, and perform a full system scan to remove Program:Win32/Contebrew.A!ml. To ensure that the machine is running well, we also recommend trying the RestoroIntego repair tool. You could again try to delete the detection history for Windows Defender – you can find more details below.
Beware of malicious sites when downloading new software
Many people like to download new software – and it's best when it's free. Unfortunately, third-party software sites serve as a perfect ground for distributing adware and similar unwanted programs, researchers warn.[2] Hence, users who carelessly download apps end up also installing additional components due to a lack of attentiveness. Of course, the distributors of PUPs are also at fault, as they are actively trying to hide promotional offers within the standalone installer.
Thus, you should always be aware that installers could and most commonly do include additional apps within them. You should always pick Advanced/Custom settings instead of recommended ones when prompted and remove all the ticks next to browser extensions, system optimizers, video players, and similar apps. You should also watch out for fine print text, misleading offers, misplaced buttons, and similar tricks used to mislead users into installing adware or other unwanted software on their machines.
There have been sightings of browser-hijacking and adware apps that come as add-ons for video games. For example, one user claimed that they were struck with an anti-virus popup when they tried downloading a mod (mods are small files that can make significant changes within a game environment) for Minecraft.[3] While such files are liked by the community, it is crucial to ensure that no unknown websites are used for such a purpose.
Program:Win32/Contebrew.A!ml removal details
If you are using Windows Defender as your main anti-malware tool, all you have to do is quarantine and remove Program:Win32/Contebrew.A!ml from your system for good. However, as already mentioned, many users claimed that they could not get rid of the continuous popups despite performing the regular actions that should contain the infection. If that has happened to you, you could check the list of the installed programs on your system, clear your browsers and uninstall unwanted extensions as explained below.
In most cases, a full Program:Win32/Contebrew.A!ml removal can not be achieved due to a bug within the Windows Defender engine. It sometimes detects the same threat repeatedly, even though it claims it has been eliminated for good. In order to bypass this, you should do the following:
- Open File Explorer by pressing Win + E
- Go to View tab at the top and tick the Hidden items option
- Now navigate to C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service folder
- In here, delete the DetectionHistory folder by pressing Shift + Del on your keyboard.
You may remove virus damage with a help of RestoroIntego. SpyHunter 5Combo Cleaner and Malwarebytes are recommended to detect potentially unwanted programs and viruses with all their files and registry entries that are related to them.

How to prevent from getting adware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
