Stop ransomware and data theft before it starts

MyDefender backs up your data and protects you from malware and other threats.
Scan your computer for viruses
MyDefender regularly scans your computer to check for viruses and other threats, stopping any suspicious activity in its tracks. How? Using a constantly updated malware database and AI behavior detection, it detects and identifies both existing and new threats. This means you’re also protected against zero-day attacks — when cyber criminals exploit software security flaws that have gone unnoticed.
Keep ransomware out
During a ransomware attack, a hacker encrypts your data, effectively holding it hostage until you've paid. MyDefender helps protect your data from ransomware attacks by preventing your files from being encrypted. It also uses advanced entropy analysis to detect any hidden ransomware lurking in the background.

Back it up to keep it safe

Even the best cyber security measures can’t fully protect you against data loss. A particularly aggressive attack, hardware failure and accidental deletion can all result in lost files. Backing up your data reduces the risk of loss. MyDefender creates regular copies of your data, backing them up in our ISO-certified data centers. You can even back up your entire computer. So, even if the worst happens, you'll be able to restore everything.

Set it and forget it cyber security

You decide which data to back up, and how often. Choose a preset plan for convenience, or adjust the settings yourself. Want to change how long files are stored? No problem. Once your backup plan is set up, the rest happens automatically.

FAQ – Frequently asked questions

Ransomware takes your data hostage. It infects your computer, and then encrypts your data so you can’t access it. The hackers demand a "ransom" or payment for decrypting your data and making it available again. The payments demanded can often be several thousand dollars, and generally have to be made in crypto currency so they can’t be traced. Ransomware attacks are on the rise and they target companies as well as individuals.

A lot of the malware that’s doing the rounds is already registered in databases. This means it can easily be recognized. This doesn’t apply to completely new viruses, which can spread far and wide within a few hours. These outbreaks are often called zero-day attacks because they wreak havoc before the virus is a day old. Antivirus software with behavior recognition uses artificial intelligence to identify typical virus patterns and defend against new threats.

Data loss can have lots of different causes. Hackers are constantly spreading new kinds of malware, and even operating system or program updates can cause vulnerabilities. Cybercriminals can exploit these weaknesses, and even the best antivirus software can’t offer 100% protection. Damaged hardware and accidental deletion can also result in lost data. That’s why it’s important to back up your data regularly. Whatever the reason for your lost files, you can restore them if you've made backup copies.

Yes! Using MyDefender as well as your antivirus software gives you much greater cyber security. Anti-ransomware keeps your computer and other devices safer, while backups mean you can restore your data if you need to.

Cloud storage is designed for accessing and sharing your files online. However, it doesn’t protect your data from damage or loss. We therefore recommend an online backup solution, especially for data that is sentimental or important to your work. Online backups automatically create copies of selected files, folders, or even entire workstations. These copies are then unaffected by any damage or malware attacks that may end up affecting the originals. Whatever happens to your data, you can restore it at any time using the backup.

Differential backups only back up the data that has changed since the last full backup, so as not to take up unnecessary storage space. Incremental backups go a step further by backing up only the changes since the last backup - be it a full or incremental backup. However, differential, and incremental backups are somewhat less reliable when restoring data because they do not contain all the data. Smart backup plans therefore combine full, differential, and incremental backups to achieve the best combination of reliability and storage utilization.

You can create one or more backup plans for each device. For each plan, you can define which data source is backed up at which time and how long the individual backups should be stored for, for example. You can also specify the type, i.e., full, differential, or incremental. In addition, the detailed settings can also help you achieve your exact wishes. To make setup easier for you, you can also select from predefined plans.

No, if you're looking for a more comprehensive backup solution, we recommend Cloud Backup.
