In summary, Win32/Kovter.A malware activities in the infected system are next:

  • Sample contains Overlay data;

But that malware does not do all these unpleasant things without delay – it may take up to several hours to cipher all of your files.

Where did I get the Win32/Kovter.A?

Ordinary ways of Win32/Kovter.A spreading are standard for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern strategy in malware spreading – you receive the e-mail that imitates some normal notifications about shipments or bank service conditions shifts. Within the email, there is a malicious MS Office file, or a 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 pretty simple, but still requires tons of awareness. Malware can hide in different spots, and it is better to stop it even before it invades your PC than to depend on an anti-malware program. General cybersecurity knowledge is just an essential thing in the modern world, even if your relationship with a computer remains on YouTube videos. That can keep you a lot of money and time which you would spend while searching for a fixing guide.
