How to install antivirus software?

To activate your antivirus software after purchasing, follow these general steps:

1. Locate the Product Key: Find the product key that came with your purchase. This could be in an email if you bought it online, or inside the packaging if you bought a physical copy.
2. Download the Software: Go to the official website of the antivirus software and download the installation file.
3. Install the Software: Run the downloaded file and follow the on-screen instructions to install the software on your device.
4. Enter the Product Key: During the installation process, you will be prompted to enter the product key. Input the key to activate your software.
5. Complete Activation: Follow any additional prompts to complete the activation process. This might include creating an account or logging into an existing one.

The dealer code and BE (Bag Engineer) number are typically provided by the antivirus software vendor or dealer from whom you purchased the software. These codes are used during the installation and activation process to verify your purchase and ensure proper registration. You should contact the vendor or dealer for assistance if you don't have these codes.

Antivirus software scans the file comparing specific bits of code against information in its database and if it finds a pattern duplicating one in the database, it is considered a virus, and it will quarantine or delete that particular file.
