  • Advertising banners are injected with the web pages that you are visiting.

  • Browser popups appear which recommend fake updates or other software.
  • Other unwanted adware programs might get installed without the user’s knowledge.

It goes without saying that you should not install software that you don’t trust.

Protect your device from viruses

Here are some basic security tips that will help you avoid malware:

  1. Install updates.

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  2. Be careful when installing programs and apps.

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  3. Don't use keygens and cracks.

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

  4. Install an ad blocker.

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back-up your data

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Secure your device.

    Keeping all the above tips in mind will keep you well on your guard, and installing a good antivirus will monitor your files for unusual changes and other warning signs. Whether you use a PC, a Mac, or a mobile device, Malwarebytes Premium is the strongest protection ever. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.
