PUA:Win32/WebCompanion Detection Overview

The PUA:Win32/WebCompanion detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware application is quite OK at scanning, however, prone to be basically unstable. It is unprotected to malware invasions, it has a glitchy interface and problematic malware removal capabilities. Therefore, the pop-up which states concerning the WebCompanion is rather just a notification that Defender has found it. To remove it, you will likely need to use another anti-malware program.

PUA:Win32/WebCompanion unwanted program is a typical example of PUA, which are quite widespread nowadays. Being free to use, it can give you “the extended functions” for the additional money. Some instances of this program type can have no useful performance at all – just the shell with the bright interface. You can see it promoted as a system optimization software, driver updater or torrent downloadings tracker. This or another way it does not provide you any kind of actual capability, exposing you to risk instead.

Is PUA:Win32/WebCompanion dangerous?

I have actually detailed that PUA:Win32/WebCompanion PUA is not as trustworthy as it claims to be. The “legitimate and valuable” program may abruptly unveil itself as a downloader trojan, spyware, backdoor, or coin miner virus. And you can never foresee what to anticipate even from different variants of WebCompanion unwanted program. That still does not say that you need to panic – probably, this nasty thing has not succeeded to do bad things to your PC.

The exact harm to your system can be caused not just because of the malware injection. A significant share of doubtful programs, like the WebCompanion app is, is just badly programmed. Perhaps, their actions are quite useful than pointless if done on particular system configurations, however, not on each one. That’s how a basic system optimization app can trigger chaos with continuous BSODs on your system. Any interruptions to the system registry are dangerous, and they are a lot more risky if completed with such programs.

How did I get this virus?

It is not easy to line the origins of malware on your computer. Nowadays, things are mixed up, and spreading tactics utilized by adware 5 years ago may be utilized by spyware these days. But if we abstract from the exact spreading way and will think about why it has success, the explanation will be quite basic – low level of cybersecurity awareness. People press on promotions on weird websites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” believing that the scary banner that says about malware is true. It is important to understand what is legitimate – to stay away from misunderstandings when trying to figure out a virus.

Nowadays, there are two of the most widespread ways of malware distribution – lure e-mails and also injection into a hacked program. While the first one is not so easy to stay away from – you need to know a lot to recognize a fake – the 2nd one is easy to handle: just do not use cracked programs. Torrent-trackers and other sources of “totally free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway place of malware. And PUA:Win32/WebCompanion is simply among them.
