MyDefender — FAQs

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.

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 save the data that has changed since the last full backup in order to avoid taking up unnecessary storage space. Incremental backups go one step further by only saving the changes since the last backup increment. However, differential and incremental backups are somewhat less reliable when restoring 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.
