MSIL/LockScreen.NZ detection is a malware detection you can spectate in your system. It usually shows up after the preliminary procedures on your PC – opening the untrustworthy e-mail messages, clicking the advertisement in the Internet or installing the program from untrustworthy sources. From the second it shows up, you have a short time to act before it begins its destructive activity. And be sure – it is far better not to await these destructive effects.

What is MSIL/LockScreen.NZ virus?

MSIL/LockScreen.NZ is ransomware-type malware. It searches for the documents on your computer, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this virus also does a lot of harm to your system. It alters the networking settings in order to avoid you from checking out the removal guides or downloading the antivirus. Sometimes, MSIL/LockScreen.NZ can additionally prevent the setup of anti-malware programs.

MSIL/LockScreen.NZ Summary

Summarizingly, MSIL/LockScreen.NZ virus actions in the infected system are next:

  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Ciphering the files located on the victim’s disk drives — so the victim cannot check these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a nightmare for the last 4 years. It is difficult to picture a more damaging virus for both individuals and corporations. The algorithms utilized in MSIL/LockScreen.NZ (generally, 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 already exists, and possibly will exist. However, that virus does not do all these bad things immediately – it may take up to a few hours to cipher all of your files. Therefore, seeing the MSIL/LockScreen.NZ detection is a clear signal that you should start the removal procedure.

Where did I get the MSIL/LockScreen.NZ?

Standard tactics of MSIL/LockScreen.NZ injection are standard for all other ransomware examples. Those are one-day landing websites where users are offered to download the free program, so-called bait emails and hacktools. Bait emails are a relatively new tactic in malware spreading – you receive the e-mail that mimics some normal notifications about deliveries or bank service conditions changes. Within the e-mail, there is a malicious MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks fairly easy, but still needs tons of recognition. Malware can hide in different spots, and it is better to prevent it even before it goes into your PC than to trust in an anti-malware program. Basic cybersecurity awareness is just an essential item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can keep you a lot of money and time which you would spend while seeking a fixing guide.
