It would help if you run a complete diagnostic virus and scan network computers on a daily and scheduled basis. This way, you won't miss any security problems in the future if you forget to run a machine check. Be sure to plan the scan for when you aren't using your device to be interrupted and during the scanning process.

3. Always download video files from a trusted source.

When purchasing a downloader application, you should proceed with caution. Check to see if the download source is trustworthy, as well as the app itself.

4. Don't open MP4 attachments in emails from unknown sources.

When you open email attachments from unsolicited emails, the sender will access your passwords, banking info, and other sensitive information on your device. They can then take your identification, cash, or, in the worst-case scenario, your sensitive data.

5. Regularly backup video files in cloud or external drive.

External hard drives are a decent backup medium - as long as there are no physical risks such as burning, flooding, or other hazards. safe cloud storage services provide an additional layer of security to you and your data by keeping your sensitive files offsite.
