Because Acronis is a backup solution, any data that was exposed and encrypted before the process was halted can be recovered from a variety of backup sources. Not only can’t alternative anti-ransomware solutions commonly end an attack once it has started, they have no way to recover any files encrypted by the attack. Acronis Active Protection detects and deflects attacks, and restores files of any size!

  • Pattern detection – Acronis Active Protection constantly observes patterns in how data files are being changed on a system. One set of behaviors may be typical and expected. Another set of behaviors may signal a suspect process taking hostile action against files.
  • Whitelist and blacklist – Acronis Active Protection is capable of detecting new threats based on already identified patterns as well as learned ones. Results must be adjusted to reduce false positive detection of things that really aren’t ransomware.
  • Self-defense of backup files – One way that criminals could choose to compromise files would be to attack the backup software itself to corrupt the backup files it creates. To protect against this, Acronis has implemented a robust self-defense mechanism that won’t let criminals disrupt the work of the Acronis application or backup file content.

    I’ve been using CryptoPrevent Premium for about a year now. Very satisfied with it. Its Honeypot feature actually saved my PC once from a ransomware. Installed it on my laptop too. Its real time protection is fairly light to run.

    Ransomware takes files from your pc, and gets a full access to use victim’s data and also demands some payment. In order to avoid paying ransom use some of the best ransomware protection tool and get your system protected.

    I have a few quick question, they are:

    • Can antivirus prevent ransomware?
    • What is the best anti ransomware software?
    • How does ransomware protection work?
    • Does Avast free protect against ransomware?
    • Gravatar

      1. Anti-virus can’t stop ransomware or most current malware only good for known virus signatures

      2. Sophos Home Edition is free and is the same exact product as the licensed Enterprise version. You can also check out Malwarebytes, SentinalOne, etc. Check youtube for demos there’s some really good ones.

      3. Ransomware protection basically looks for suspicious activity or file access launched from a process or program. Example: User opens an infected file, that file runs a script, that launches powershell, that runs a command(s) or script looking for specific files or file types, then launches a process that encrypts the files. Anti-ransomware seeks to detect and interrupt this process before the files are encrypted.

      4. Don’t know much about Avast

    Non of tese so called anti ransomware products are free. Their anti virus maybe free but after downloading them they all require a paid upgrade to access anti ransomware.
