.EXTE File Virus – More Information
Being a variant of the CryptoMix ransomware infections, this virus aims to perform multiple different types of activities on the computers infected by it. It all starts with it’s malicious loader type of file, whose primary purpose is to extract the payload of the .EXTE ransomware virus. Such loader may pretend to be:
- Legitimate setup, uploaded online.
- Legitimate document sent to you over the web (Word, .PDF, Excel).
- A game crack or any other activation software uploaded on suspicious websites.
- A web link or a button which causes a drive-by download when you click on it. Such are often spammed as comments or other suspicious messages. Sometimes they are featured in spam e-mails as well.
