Written by Daniel Zimmerman

What is PUABundler:Win32/ICBundler?

PUABundler:Win32/ICBundler is a potentially unwanted application (PUA) detection used by antivirus software to identify a specific type of bundling software. It is categorized as a bundler because it bundles legitimate software installations with additional software or offers, often leading to unwanted or unexpected installations on the user’s system.

ICBundler refers to the specific bundler variant that has been identified and classified by antivirus vendors. Bundlers like PUABundler:Win32/ICBundler may be distributed through various channels, including freeware or shareware downloads, deceptive advertisements, or software bundles that lack transparency in disclosing the additional installations.

While not necessarily malicious, PUABundler:Win32/ICBundler can cause unwanted behaviors such as displaying intrusive advertisements, modifying browser settings, or collecting user data without explicit consent. It is generally recommended to exercise caution when downloading and installing software from unfamiliar sources and to carefully review the terms and conditions during installations to avoid inadvertently installing unwanted software.

ICBundler is a detection for BitTorrent

When you have a BitTorrent app installed on your computer, Microsoft Defender may detect PUABundler:Win32/ICBundler. BitTorrent is a client for peer-to-peer networking, allowing you to obtain various files from other computers over the internet by connecting to their IP addresses. P2P networks are frequently exploited for distributing viruses, which is why Defender identifies it and suggests blocking the “threat.”

It’s important to note that servers and IP addresses are often shared by multiple websites. While the files you download through BitTorrent may be safe, some of the sites hosted on the IP addresses connected to by BitTorrent could be malicious. Nevertheless, it’s crucial to understand that BitTorrent itself is not a threat.

File sharing involves utilizing technology that enables internet users to share files stored on their individual computers. Peer-to-peer (P2P) applications, such as those used for sharing music files, are among the most common types of file-sharing technology. However, P2P applications introduce security risks that can potentially endanger your PC.

Microsoft Defender & PUABundler:Win32/ICBundler

If you have seen a message suggesting the “PUABundler:Win32/ICBundler found”, you have nothing to worry about. BitTorrent application cannot inject a virus of any sort into your computer. Such messages just alarm you that further usage of the BitTorrent app may be dangerous. And these words are not just rumors – a lot of ransomware attack cases in 2020 happened exactly after the use of malevolent P2P seeding.

Microsoft Defender: “PUABundler:Win32/ICBundler”

There are several ways to terminate that risk. You can either delete the BitTorrent, or ignore that notification, but both of these ways will not guarantee you safety. Virus distributors are extremely sly, so it is important to secure your PC from any kind of attack. Microsoft Defender is not a thing you can rely on. That program is integrated into the system and can be stopped through the Group Policies in several clicks. Malware creators exploit that security breach heavily, hence, you will not be able to scan your device and remove the threats after the attack. To guarantee that PUABundler:Win32/ICBundler will not turn in something serious, and to provide you with invulnerable antivirus protection, you can use GridinSoft Anti-Malware.

How to scan for malware, spyware, ransomware, adware, and other threats.

If your computer exhibits exceptional slowness, the website opens peculiarly, or if you encounter unexpected advertisements, it is possible that PUABundler:Win32/ICBundler is more than just a daunting notification. The range of viruses you can acquire is extensive, and their symptoms are even more varied. Spyware will undoubtedly track all your activities or redirect your searches and web pages to unwanted destinations. Adware may infect your browser and the entire operating system, bombarding you with intrusive banners.

Regardless of the type of issue you are experiencing with your PC, the initial step is to examine it using Gridinsoft Anti-Malware.

How to scan your PC for viruses like ICBundler?

The main sign of malware injection, which you can spectate on your device, is the general slowdown. Malware activity can consume a lot of hardware capacity, especially if we are talking about coin miners. You must not ignore these signs, because, as I have mentioned before, the efficiency of malware depends on the time you give it for actions. Forehanded detection of malicious items is also the way to prevent the appearance of various other viruses.

Regardless of the exact symptoms, you need to scan your device with the proper anti-malware software. Besides the aforementioned disadvantages, Microsoft Defender also has a problem with database updates. That antivirus tool cannot update its detections as other tools do. To apply the new databases, you need to install all past detection database updates and get the newest ones, performing several reboots in the process. Because of such a long update cycle, Defender cannot provide the proper scanning functionality. GridinSoft Anti-Malware can detect viruses at any moment since its detection lists are updated every hour.

Use Safe Mode to prevent the virus launching.

It’s not enough to use the antivirus for the security of your computer. It would help if you had much more extensive antivirus software. Not all malware can be detected by regular antivirus scanners that mainly look for virus-type dangers. Your system may teem with “trash”, for instance, toolbars, browser plugins, unwanted online search engines, bitcoin-miners, as well as various other sorts of unwanted software used for earning money on your inexperience. Beware while downloading and installing apps online to stop your tool from being filled with unwanted toolbars and various other junk applications.

However, if your system has already obtained a certain unwanted application, you will make up your mind to erase it. The majority of the antivirus programs are uncommitted regarding PUAs (potentially unwanted applications). To get rid of such programs, I suggest acquiring Gridinsoft Anti-Malware. If you use it regularly to scan your PC, it will certainly help you eliminate malware that was missed out on by your antivirus software.
