Norton Antivirus Plus helps protect you from all three these identity theft threats.

Can Norton Antivirus Plus Block Popups?

There are two answers to this question.

First, your web browser generally handles popup applications you see while surfing the Internet. Web browsers have limited interaction with antivirus software you have installed on your machine. Like other antivirus software, Norton Antivirus Plus does not stop popups that work with the computer’s internet browser. The reason for this is that antivirus software makers do not want to alter the browser’s normal functioning. Otherwise it could result in the user’s web experience getting worse, changes to web browser security settings and compatibility issues.

Second, some malware actually launches popups from the desktop, not your browser. Norton Antivirus Plus can stop and remove these popup-generating programs.

Can Norton Antivirus Plus Protect Against Hackers?

Yes. Norton offers the following methods to protect your system from hackers:

  • Data backup
  • VPN
  • Password Manager
  • Firewall
  • Anti-spyware
  • Anti-worms
  • Anti-ransomware
  • Anti-scareware
  • Anti-phishing

Having these protections on your system can save it from hackers who may attempt to turn your computer into a “zombie” to send spam emails, or commit extortion.

Does Norton Antivirus Plus Block Spyware?

Norton Antivirus Plus detects and remove various types of spyware.

Spyware is a malicious type of software that tries to “spy” on users. It can come in many forms, including:

  • Cookies
  • Trojans
  • Adware
  • Rootkits
  • System monitors
  • Web beacons
  • Keyloggers

Trojans are often used to get spyware onto users’ systems and these can also be detected and removed. Norton Antivirus Plus works as a standalone antivirus suite and can provide complete protection against all types of dangerous spyware.

Does Norton Antivirus Plus Block Scareware?

Yes. Norton Antivirus Plus will block scareware with its firewall. It can also detect and remove it from your system.

Scareware is malware that aims to scare the user into spending money on additional software downloads. This can involve pop-up ads warning the user that their system is infected with a slew of viruses. Norton Antivirus Plus protects againsts these types of scareware.
