  • Seamless and easy to use.
    I love that I can install (so easy) and pretty much forget about it because the software protects 24/7. It gives me instant information that I am protected even if I have been online for two or three hours or more!
  • Low resources and high, high-end benefits.
    The same strong anti-malware engine for your desktop and laptop comes to the Android. Runs seamlessly in the background protecting you, and does a great job of keeping your system secure.

Frequently Asked Questions

If your device has gotten a virus or malware infection, there are some telltale signs, including: 

  • Reduced Speed: Your device slows down significantly. 
  • Pop-ups: You have started to see a lot of unexpected pop-ups. 
  • System crashing: Your system unexpectedly crashes, either by freezing or by giving you a blue screen. 
  • Loss of disk space: A lot of your device’s storage has been taken up unexpectedly. 
  • Settings changed: Device or browser settings change without you changing them. 
  • Files encrypted: Ransomware has locked you out of your files or your entire device. 

Different types of malware use your device’s resources in different ways, such as making it part of a botnet to perform DDoS attacks, mining cryptocurrency without your knowledge, or other nefarious activities.
