What is PUA:Win32/Puwaders.B!ml?

PUA:Win32/Puwaders.B!ml – a detection name for adware app that is hard to get rid of

PUA:Win32/Puwaders.B!mlPUA:Win32/Puwaders.B!ml is a detection name for a potentially unwanted program known as adware

PUA:Win32/Puwaders.B!ml is a Windows Defender-assigned name for an adware application that has infiltrated your computer. It is based on heuristic analysis, which means that security software detected the potentially unwanted program based on the way it functions rather than its name. As a result, there could be many different apps that are hiding behind the PUA:Win32/Puwaders.B!ml virus name.

Adware, which is also known as ad-supported software, is a minor computer threat that typically arrives on the system without asking for direct permission, as developers use fake updates or software bundles to distribute it. Once installed, the app would change certain browser settings (in some cases, system file modification can occur as well) in order to deliver users popups, banners, deals, coupons, offers, and other commercial content, regardless if Google Chrome, Mozilla Firefox, or MS Edge is used.

If you are looking for the PUA:Win32/Puwaders.B!ml removal solutions because the threat seems to be coming back, we will explain why this happens and ways on how to get rid of this annoying infection once and for all.

Name PUA:Win32/Puwaders.B!ml
Type Adware, potentially unwanted program
Distribution Software bundles, third-party websites, deceptive ads, fake Flash Player updates
Symptoms Windows Defender detects a potentially unwanted program repeatedly; potential browser settings changes; increased number of ads and redirects to unsafe sites
Dangers Installation of other potentially unwanted programs or malware, monetary losses, sensitive information disclosure to unknown parties
Elimination We recommend attempting to delete the PUP manually as per instructions below. If security software keeps detecting the same threat again, you need to delete Windows Defender history – check instructions below. Additionally, you should scan your computer with an alternative security tool, such as SpyHunter 5Combo Cleaner
Further steps Malware or adware infections can diminish the performance of your computer or cause serious stability issues. Use FortectIntego to remediate your device and ensure that the virus damage is fixed

Adware is usually not considered a dangerous piece of software, although some examples show the complete opposite. In most cases, the adware will hijack web browsers and inject advertisements into them, all while spying on users' web browsing activities in the background. Programs like PUA:Win32/Puwaders.B!ml typically have limited or no useful functionality and are not desired by most users.

In this particular case, the so-called PUA:Win32/Puwaders.B!ml virus might change your homepage without permission, redirect all your searches to another provider (such as Yahoo or Bing), install unwanted browser extensions, and drops its files all over the system. Certain modifications within the Windows registry can later cause problems with the computer's stability, so we recommend using FortectIntego after the threat is eliminated.

There is no doubt that you should not hesitate to remove PUA:Win32/Puwaders.B!ml from your machine as soon as possible, as it can not only diminish web browsing experience but also put your online privacy and security at risk (some links and redirects might bring you to malicious websites).

Unfortunately, most of the users who had Windows Defender detect this threat were unable to remove PUA:Win32/Puwaders.B!ml from their system as they would with any other detection. Even after their cleared web browsers cookies, web data and uninstalled the app in question, it would still return the next time the security software would perform a scan.

The truth is that repeated detection of the virus is caused by a bug within Windows Defender running on Windows versions 2004. Since the release of this OS version, Windows began flagging potentially unwanted programs as malicious, and many users complained that they are unable to remove many of such detections.

To get rid of the repeated detection, you should delete Protection History within Windows Defender. For more details, check the removal section below.

Potentially unwanted program prevention tips

In most cases, users find potentially unwanted programs installed on their systems without permission and tend to believe that they simply self-installed. However, adware does not possess such functionality, as these programs are relatively simple, and users install PUPs themselves (without the intention of doing so). It does not change the fact that the developers of freeware and sites that distribute them often to engage in deceptive practices in order to spread the software around the world.

There two main methods of how adware and other unwanted programs are distributed – software bundling and deceptive ads/fake updates. Security experts recommend the following to avoid unwanted infiltration of potentially dangerous software:

  • If possible, download apps from official sources only;
  • Never attempt to download pirated programs or software cracks;
  • When visiting third-party sites, keep in mind that optional apps are likely to insert into the installer of your desired program;
  • When you launch the installation wizard, do not rush the steps, and read the instructions carefully;
  • When prompted, always pick Advanced/Custom settings instead of Recommended/Quick ones;
  • Remove all ticks from pre-ticked checkboxes;
  • Always read the fine print;
  • Decline all the offers and watch out for misleading button placements (“Skip offer” is often placed on the right side of the pop-up window, resulting in the unintentional installation of PUPs);
  • Install reliable security software that can warn you about unwanted programs.

The correct way to remove PUA:Win32/Puwaders.B!ml virus

PUA:Win32/Puwaders.B!ml removal proved to be more difficult than it should have been to most users. Potentially unwanted programs rarely engage in establishing persistence techniques on a computer, so they can be eliminated just like any other program or with security software. If you were unsuccessful in doing just that, you should employ alternative security software, such as SpyHunter 5Combo Cleaner or Malwarebytes, and perform a full system scan to ensure that all the malicious components are gone.

If you are having a different problem (you can't remove PUA:Win32/Puwaders.B!ml because the detection keeps coming back), you need to clear Windows Defender's scan history in order to make it stop detecting its own results. This is a known bug, although it does not happen every time.

How to prevent from getting adware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
