Any malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking of ethicality – they utilize all possible methods. Grabbing your personal data, receiving the payments for the ads you watch for them, utilizing your system components to mine cryptocurrencies – that is not the full list of what they do. Do you want to be a riding horse? That is a rhetorical question.

What does the pop-up with Adware:MSIL/Tnega!MSR detection mean?

The Adware:MSIL/Tnega!MSR detection you can see in the lower right corner is demonstrated to you by Microsoft Defender. That anti-malware application is quite OK at scanning, but prone to be basically unreliable. It is vulnerable to malware attacks, it has a glitchy interface and problematic malware removal capabilities. For this reason, the pop-up which states about the Tnega is simply an alert that Defender has actually recognized it. To remove it, you will likely need to make use of another anti-malware program.

The exact Adware:MSIL/Tnega!MSR malware is a really undesirable thing. This malware shows you an unprecedented quantity of promotions. Have you ever visited the doorway sites? They are filled just with banners – blinking, badly created and with strange information. Adware does the equivalent thing to all pages you visit. That malware brings money to its developers in a very tricky way. You check the banners – they get money. Moreover, these banners oftentimes include deceptive and sometimes shocking content. Penis enlargement, pornography sites advertisements, Microsoft virus alertsall these things are usual for adware.

Is Adware:MSIL/Tnega!MSR dangerous?

Adware like Tnega one is not something contrasty, compared to other advertising malware. But as it was mentioned, the banners it demonstrates to you are pretty frequently full of fraudulent content. Even if you can identify scam from adware – do you really like seeing ads for free? Specifically ones that cover your browser window and distract you from your working process? It seems that we already know the answer.

How did I get this virus?

It is difficult to trace the sources of malware on your computer. Nowadays, things are mixed, and distribution tactics chosen by adware 5 years ago can be used by spyware nowadays. But if we abstract from the exact distribution way and will think about why it works, the explanation will be really basic – low level of cybersecurity knowledge. Individuals press on promotions on weird sites, open the pop-ups they get in their browsers, call the “Microsoft tech support” assuming that the scary banner that states about malware is true. It is essential to recognize what is legit – to avoid misunderstandings when attempting to determine a virus.

Nowadays, there are two of the most common methods of malware spreading – lure e-mails and injection into a hacked program. While the first one is not so easy to evade – you must know a lot to understand a fake – the 2nd one is very easy to handle: just do not use cracked applications. Torrent-trackers and various other providers of “totally free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway point of malware. And Adware:MSIL/Tnega!MSR is just amongst them.
