It often shows up after the preliminary activities on your PC – opening the suspicious e-mail messages, clicking the banner in the Internet or setting up the program from untrustworthy resources.

What is Win32/Filecoder.OLC virus?

Win32/Filecoder.OLC is ransomware-type malware. It searches for the files on your disk drives, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, 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 articles or downloading the anti-malware program. In rare cases, Win32/Filecoder.OLC can even stop the launching of anti-malware programs.

Win32/Filecoder.OLC Summary

In summary, Win32/Filecoder.OLC virus actions in the infected PC are next:

  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Ciphering the documents kept on the target’s drives — so the victim cannot open these documents;
  • Blocking the launching of .exe files of anti-virus programs
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a nightmare for the last 4 years. It is hard to picture a more hazardous malware for both individual users and businesses. The algorithms utilized in Win32/Filecoder.OLC (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 currently exists, and possibly will exist. But that virus does not do all these terrible things instantly – it can take up to a few hours to cipher all of your documents. Hence, seeing the Win32/Filecoder.OLC detection is a clear signal that you have to start the removal procedure.

Where did I get the Win32/Filecoder.OLC?

Typical methods of Win32/Filecoder.OLC injection are typical for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a relatively new strategy in malware distribution – you get the e-mail that mimics some routine notifications about deliveries or bank service conditions changes. Within the email, there is a malicious MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks quite uncomplicated, but still demands a lot of focus. Malware can hide in different spots, and it is much better to stop it even before it goes into your PC than to rely on an anti-malware program. General cybersecurity awareness is just an essential item in the modern world, even if your relationship with a PC remains on YouTube videos. That can save you a great deal of money and time which you would spend while searching for a fix guide.
