It usually appears after the preliminary procedures on your PC – opening the untrustworthy email messages, clicking the banner in the Internet or mounting the program from unreliable resources.

What is Ransom:Win32/KeepLock.A virus?

Ransom:Win32/KeepLock.A is ransomware-type malware. It searches for the documents on your disks, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files inaccessible, this malware also does a ton of damage to your system. It modifies the networking setups in order to prevent you from looking for the removal guidelines or downloading the antivirus. In some cases, Ransom:Win32/KeepLock.A can also block the setup of anti-malware programs.

Ransom:Win32/KeepLock.A Summary

In total, Ransom:Win32/KeepLock.A virus actions in the infected computer are next:

  • Authenticode signature is invalid;
  • Encrypting the documents located on the target’s disks — so the victim cannot check these files;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of security tools

Ransomware has actually been a headache for the last 4 years. It is difficult to realize a more harmful malware for both individual users and organizations. The algorithms utilized in Ransom:Win32/KeepLock.A (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these terrible things without delay – it can require up to several hours to cipher all of your files. Therefore, seeing the Ransom:Win32/KeepLock.A detection is a clear signal that you must begin the removal procedure.

Where did I get the Ransom:Win32/KeepLock.A?

Ordinary tactics of Ransom:Win32/KeepLock.A spreading are common for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free app, so-called bait emails and hacktools. Bait emails are a pretty modern method in malware spreading – you receive the email that simulates some routine notifications about deliveries or bank service conditions modifications. Inside of 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 easy, however, still needs a lot of attention. Malware can hide in different places, and it is better to prevent it even before it gets into your PC than to rely upon an anti-malware program. Basic cybersecurity awareness is just an important item in the modern-day world, even if your relationship with a PC remains on YouTube videos. That can save you a great deal of time and money which you would certainly spend while trying to find a solution.
