PBot adware, also called PythonBot, is an ad-supported program[1] which is written in Phyton. Posing a danger to its victims in several ways, this virus cannot be called a traditional PUP that can be removed by resetting your web browser. Once inside the computer, the virus displays hundreds of ads which are mostly based on Javascript. Also, it causes redirects to dubious pages and is trying to infect web browsers with other malicious extensions. The Pbot virus can also travel together with a miner which is launched to generate cryptocurrency right after the system is infected.

PythonBot is designed to infect Windows operating system only. It is already detected by Kaspersky, Dr. Web, Sophos, Symantec, Avast, Avira and many other anti-virus vendors.[2] It regularly changes its location to keep spreading around and make the removal process more complicated. Its distribution relies on .hta file which additionally downloads NSIS installer and saves it on %AppData% location.

When installed, malware causes numerous changes in the system, including injecting malicious DLLs into web browsers and installing ad extensions without user's notice. According to tech experts,[3] this adware-type program can also be added to the Trojan category because of its ability to travel together with cryptocurrency miners and similar malware.[4]

After setting the PC according to its preferences, Pbot might cause such damage:

  • The loss of important data;
  • Serious system malfunction because of crypto mining;
  • Continuous pop-up ads and redirects while browsing the Internet;
  • Making the system vulnerable to other threats;
  • Leading its victims to money loss or even identity theft.

Information tracking is also implemented by PythonBot, which typically collects users' search terms, mostly visited domain names, computer's IP address, its location and similar data. 

If you have even the slightest thought that you could be infected with this threat, we strongly recommend performing PBot removal on your computer. Keep in mind that you are dealing with the serious malware, so you should use special tools for its full elimination from the system, such as Reimage. The longer it will remain on your system, the bigger the damage can be. Your Windows operating system can become unusable if you do not take care of the threat.

While you can reset your web browsers affected by this adware, this procedure won't help you to get rid of the threat fully.

  • Spam messages;
  • False updates;
  • Peer-to-peer networks;
  • Online game sites;
  • Misleading ads;
  • And many more.

If you want to keep your computer system safe from this and other adware-related infections, you need to avoid harmful content at all costs. First of all, what you have to do is eliminate all suspicious looking sites from your browsing routine as they might be filled with fake websites and similar content.

To continue, avoid spam and questionable emails – better send an inquiry about the message to make sure that the sender is real and has nothing to do with cybercriminals. Such emails often include malicious content which, once opened, drops malware onto the system.

You should also be careful with online game sites or P2P networks. Install an antivirus to prevent unwanted infiltration of malware from these sites. And finally, keep yourself focused while browsing the web as there are lots of dangers hiding in various sites and waiting for somebody to enter them.
