Any malware exists with the only target – gain money on you¹. And the programmers of these things are not thinking about morality – they utilize all available ways. Stealing your private data, receiving the payments for the advertisements you watch for them, exploiting your CPU and GPU to mine cryptocurrencies – that is not the complete list of what they do. Do you like to be a riding equine? That is a rhetorical question.

What does the pop-up with PUA:Win32/OpenCandy detection mean?

The PUA:Win32/OpenCandy detection you can see in the lower right side is shown to you by Microsoft Defender. That anti-malware application is quite OK at scanning, however, prone to be generally unstable. It is unprotected to malware invasions, it has a glitchy user interface and problematic malware clearing capabilities. Thus, the pop-up which says concerning the OpenCandy is just an alert that Defender has actually identified it. To remove it, you will likely need to use a separate anti-malware program.

Microsoft Defender: “PUA:Win32/OpenCandy”

The exact PUA:Win32/OpenCandy virus is a really nasty thing. This malware demonstrates to you an unprecedented amount of advertisements. Have you ever saw the doorway pages? They are filled up only with banners – blinking, improperly designed and with weird information. Adware does the same thing to all pages you open. That malware brings profit to its developers in a very tricky way. You check the banners – they get profit. Furthermore, these banners frequently have deceptive and explicit content. Penis enlargement, porn websites advertisements, Microsoft virus alerts – all these things are usual for adware.

Adware Summary:

Is PUA:Win32/OpenCandy dangerous?

Adware like this one is not something contrasty, compared to other advertising malware. But as it was pointed out, the banners it shows to you are pretty often loaded with phony content. Even if you can distinguish scam from adware – do you truly like watching promotions for free? Specifically ones that cover your browser window and distract you from your working task? It looks that we already understand the answer.

How did I get this virus?

It is hard to trace the origins of malware on your computer. Nowadays, things are mixed, and spreading ways used by adware 5 years ago may be used by spyware these days. But if we abstract from the exact distribution tactic and will think about why it works, the reply will be pretty basic – low level of cybersecurity awareness. People click on promotions on weird sites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the scary banner that states about malware is true. It is necessary to know what is legit – to stay away from misunderstandings when trying to determine a virus.

Microsoft Tech Support Scam

Nowadays, there are two of the most extensive methods of malware distribution – bait e-mails and also injection into a hacked program. While the first one is not so easy to stay away from – you should know a lot to recognize a counterfeit – the 2nd one is very easy to address: just do not use hacked programs. Torrent-trackers and other sources of “free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway place of malware. And PUA:Win32/OpenCandy is just one of them.
