.promos Files Virus – Distribution
The main infection vector used by authors of .promos files virus is likely to be the malspam. Malspam (spam emails that deliver malicious code) is a commonly used technique used for the spread of ransomware like .promos. There are several common components that are typical of these emails:
- An URL address presented in the form of an in-text link, button, image, banner or other form. Once loaded in the browser the web page associated with this link usually triggers an automatic download process of the malicious ransomware payload. After downloading the payload the same page usually activates specific scripts that execute it directly on your PC.
- An attachment that contains the malware in it. Usually, according to the text message this file should be reviewed as soon as possible due to the importance of its information. The moment you open it on your device is the moment when you trigger the infection process with .djvu files virus. This file may be a familiar type of file such as .rar, .zip, .7z, .docx When infected such a file could be set to evade active security measures and complete the attack without leaving you any chance of detecting the malicious activities it performs on the background.
Since the security of your device and your data is of paramount importance we recommend you to use the help of free online scanners like VirusTotal and ZipeZip every next time you receive a questionable email that contains any of the mentioned components. With the help of these scanners, you will easily identify whether the components are malicious or not.
