- You may get a pop-up alert warning you that your system is infected and it claims to clean up your system or similar fear injecting pop-ups. As I said before a genuine antivirus would never advertise using pop-ups.
- You may be invited for a free security scan.
- You may come across an advertisement clean your system or to clean your registry or to enhance your computer performance, etc.
- You may come across a website which claims that it has scanned your computer and asks you to download a software.
- If an attempt is made through e-mail the message is not addressed to the user receiving the mail instead it would be like to the account holder, dear customer, etc.
- As you can see in the above image this is on a web browser, it is not on screen from my computer but the website designer makes it look like my computer.
- Injecting fear into the users mind and prompting ‘Buy it right now’, a genuine antivirus always lets you download a free version before you buy it.

To close the pop-up
If you come across a pop-up claiming you are infected, what would you do? Close it by clicking on "X" ? that would be your first and the last mistake. Don't click on "No" or "Cancel" or even "X" on the top right corner of the pop-up. If You click it you will open the door to malware as some of the malwares are designed in such a way that any of those buttons can activate it. What should you do then? First close the browser, then If you using windows:
- Press Ctrl + Alt + Del and open the task manager.
- Scroll down the dialog box and find the name of the pop-up window and select it.
- After you have selected it, click on the end task.
