PWS:Win32/Zbot!AF detection is a malware detection you can spectate in your computer. It generally appears after the provoking procedures on your computer – opening the untrustworthy email, clicking the advertisement in the Web or setting up the program from suspicious sources. From the moment it appears, you have a short time to take action until it begins its destructive activity. And be sure – it is far better not to await these malicious effects.

What is PWS:Win32/Zbot!AF virus?

PWS:Win32/Zbot!AF is ransomware-type malware. It looks for the documents on your disk drives, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware also does a ton of harm to your system. It changes the networking settings in order to prevent you from reading the elimination tutorials or downloading the antivirus. In rare cases, PWS:Win32/Zbot!AF can even block the launching of anti-malware programs.

PWS:Win32/Zbot!AF Summary

Summarizingly, PWS:Win32/Zbot!AF ransomware actions in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Presents an Authenticode digital signature;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Ciphering the files kept on the victim’s disk drive — so the victim cannot open these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a horror story for the last 4 years. It is difficult to realize a more damaging malware for both individual users and organizations. The algorithms used in PWS:Win32/Zbot!AF (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. But that virus does not do all these horrible things immediately – it may require up to a few hours to cipher all of your documents. Therefore, seeing the PWS:Win32/Zbot!AF detection is a clear signal that you need to begin the clearing process.

Where did I get the PWS:Win32/Zbot!AF?

Standard methods of PWS:Win32/Zbot!AF spreading are common for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a relatively modern tactic in malware distribution – you receive the email that simulates some standard notifications about shippings or bank service conditions modifications. Within the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks quite simple, but still requires a lot of attention. Malware can hide in different spots, and it is much better to prevent it even before it gets into your PC than to rely upon an anti-malware program. Simple cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That may keep you a lot of time and money which you would spend while searching for a fixing guide.
