Navigate to Settings and then select Parental Control.
Choose Application Control.
Click on Add and select the application’s executable file (.exe) you wish to block.
After adding, click Modify User Settings and change the setting from Do not filter to Block applications in the block list.

Initiate the initial configuration for backup, as it doesn’t work automatically without setup.
Add a new backup set, specifying the files, folders, or drives you wish to protect.
Configure the backup destination (e.g., an external drive) and schedule for regular backups.

Reason To Do This: Regular data backups are essential for protecting your precious files against data loss due to system failures, ransomware attacks, or accidental deletion. Proper configuration ensures your data is recoverable when needed.

Open the K7 Security Software main console.
Go to Settings and then open the Antivirus and Antispyware section.
Select Real-Time Protection.
Click on Manage Exclusions.
To add a file or folder, click Add Entry, then browse to or enter the file/folder path.
Ensure Exclude from Real-Time Scanner is selected and click OK to save.

Reason To Do This: Excluding specific files or folders from scans can prevent conflicts with legitimate software or speed up scan times by skipping known safe items. Use this feature cautiously to avoid creating security vulnerabilities.
