Ransom:Win32/Basta.PB!MTB Detection overview

The Ransom:Win32/Basta.PB!MTB detection you can see in the lower right side is displayed to you by Microsoft Defender. That anti-malware program is good at scanning, but prone to be generally unstable. It is defenseless to malware invasions, it has a glitchy user interface and problematic malware removal capabilities. Therefore, the pop-up which states about the Basta is rather just an alert that Defender has actually found it. To remove it, you will likely need to make use of a separate anti-malware program.

The exact Ransom:Win32/Basta.PB!MTB infection is a very undesirable thing. It is present inside of your computer under the guise of something normal, or as a part of the application you downloaded at a forum. Therefore, it makes everything to weaken your system. At the end of this “party”, it downloads other viruses – ones which are choosen by cyber burglars who manage this malware. Hence, it is almost impossible to predict the effects from Basta actions. And the unpredictability is one of the most upleasant things when it comes to malware. That’s why it is rather not to choose at all, and don’t give it even a single chance to complete its task.

Is Ransom:Win32/Basta.PB!MTB dangerous?

As I have pointed out, non-harmful malware does not exist. And Ransom:Win32/Basta.PB!MTB is not an exception. This malware changes the system configurations, modifies the Group Policies and registry. All of these things are crucial for correct system operating, even in case when we are not talking about PC safety. Therefore, the virus which Basta contains, or which it will inject later, will squeeze out maximum profit from you. Cybercriminals can grab your data, and then push it at the black market. Using adware and browser hijacker functions, embedded in Ransom:Win32/Basta.PB!MTB virus, they can make profit by showing you the advertisements. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is difficult to trace the sources of malware on your PC. Nowadays, things are mixed, and distribution ways chosen by adware 5 years ago can be utilized by spyware nowadays. However, if we abstract from the exact distribution tactic and will think of why it works, the explanation will be pretty uncomplicated – low level of cybersecurity knowledge. Individuals click on advertisements on odd sites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the odd banner that says about malware is true. It is necessary to know what is legitimate – to prevent misunderstandings when trying to identify a virus.

Microsoft Tech Support Scam

Microsoft Tech Support Scam

Nowadays, there are two of the most widespread tactics of malware distribution – 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 recognize a fake – the 2nd one is very easy to solve: just don’t use hacked programs. Torrent-trackers and various other providers of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway place of malware. And Ransom:Win32/Basta.PB!MTB is simply within them.

How to remove the Ransom:Win32/Basta.PB!MTB from my PC?

Ransom:Win32/Basta.PB!MTB malware is incredibly difficult to remove by hand. It stores its documents in several places throughout the disk, and can get back itself from one of the parts.
