PUABundler:Win32/BundleInstaller Detection Overview

The PUABundler:Win32/BundleInstaller detection you can see in the lower right side is displayed to you by Microsoft Defender. That anti-malware application is good at scanning, however, prone to be basically unstable. It is unprotected to malware attacks, it has a glitchy user interface and bugged malware removal features. For this reason, the pop-up which says about the BundleInstaller is simply an alert that Defender has detected it. To remove it, you will likely need to make use of a separate anti-malware program.

PUABundler:Win32/BundleInstaller unwanted program is a case in point of PUA, which are pretty widespread nowadays. Being free to use, it may offer you “the extended functionality” for the additional money. Some instances of this program type can have no useful performance whatsoever – only the shell with the colorful interface. You can see it promoted as a system optimization tool, driver updater or torrent downloadings tracker. This or another way it does not give you any type of actual capability, exposing you to risk instead.

Is PUABundler:Win32/BundleInstaller dangerous?

I have already mentioned that PUABundler:Win32/BundleInstaller PUA is not as harmless as it pretends to be. The “legit and helpful” program may suddenly discover itself as a downloader trojan, spyware, backdoor, or coin miner malware. And you can never estimate what to anticipate even from different variants of BundleInstaller unwanted program. That still does not imply that you need to panic – probably, this nasty thing has not succeeded to do negative things to your computer.

The exact harm to your system can be created not just as a result of the malware injection. A large share of doubtful programs, like the BundleInstaller app is, is just improperly developed. Potentially, their actions are quite effective than pointless if done on particular system configurations, but not on each one. That’s how a simple system optimization program can create disorder with continuous BSODs on your system. Any type of interruptions to the system registry are not very safe, and they are a lot more risky if performed with such programs.

How did I get this virus?

It is not easy to line the sources of malware on your PC. Nowadays, things are mixed, and spreading ways used by adware 5 years ago can be used by spyware these days. But if we abstract from the exact distribution way and will think about why it has success, the reply will be very simple – low level of cybersecurity understanding. Individuals press on promotions on weird websites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” thinking that the odd banner that says about malware is true. It is essential to understand what is legitimate – to prevent misconceptions when trying to identify a virus.

Nowadays, there are two of the most common ways of malware spreading – lure e-mails and also injection into a hacked program. While the first one is not so easy to evade – you should know a lot to understand a fake – the second one is simple to handle: just don’t utilize cracked programs. Torrent-trackers and other sources of “free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway place of malware. And PUABundler:Win32/BundleInstaller is simply one of them.
