MSIL/LockScreen.ZG detection is a malware detection you can spectate in your system. It generally appears after the preliminary procedures on your computer – opening the dubious e-mail messages, clicking the advertisement in the Web or mounting the program from unreliable sources. From the instance it shows up, you have a short time to take action until it begins its malicious activity. And be sure – it is much better not to wait for these malicious actions.

What is MSIL/LockScreen.ZG virus?

MSIL/LockScreen.ZG is ransomware-type malware. It looks for the documents on your computer, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware also does a ton of damage to your system. It changes the networking setups in order to avoid you from looking for the removal guidelines or downloading the antivirus. Sometimes, MSIL/LockScreen.ZG can even prevent the setup of anti-malware programs.

MSIL/LockScreen.ZG Summary

In summary, MSIL/LockScreen.ZG virus activities in the infected computer are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Creates RWX memory;
  • Guard pages use detected – possible anti-debugging.;
  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Installs itself for autorun at Windows startup;
  • Encrypting the documents located on the target’s disk drive — so the victim cannot check these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a headache for the last 4 years. It is challenging to imagine a more harmful virus for both individual users and companies. The algorithms used in MSIL/LockScreen.ZG (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy actually exists, and possibly will exist. However, that malware does not do all these unpleasant things without delay – it can require up to a few hours to cipher all of your documents. Hence, seeing the MSIL/LockScreen.ZG detection is a clear signal that you should start the clearing process.

Where did I get the MSIL/LockScreen.ZG?

General tactics of MSIL/LockScreen.ZG spreading are basic for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a pretty modern method in malware spreading – you get the e-mail that mimics some standard notifications about shippings or bank service conditions changes. Within the e-mail, there is a malicious MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks quite simple, however, still requires a lot of recognition. Malware can hide in various spots, and it is much better to prevent it even before it invades your system than to rely upon an anti-malware program. General cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can save you a lot of money and time which you would spend while looking for a fix guide.
