FAQs

What are the signs of spyware infection?

The most common signs of a spyware infection include:


If you experience any of these issues, run a malware scan with a free antivirus.

How can I get rid of spyware for free?

The best way to remove spyware is to use an anti-spyware scanner. Download and install a reliable free antivirus solution, and it will detect and remove the spyware from your device. Then, keep your device clean by removing junkware, PUPs, and other unnecessary software that can slow down your computer.

Is spyware the same as malware?

All spyware is malware, but not all malware strains are spyware. Spyware is a type of malware that tracks your activity and collects information about your digital habits, and it’s designed to be hard to detect.

Why is spyware dangerous?

Spyware is a particularly dangerous form of malware because it’s so invasive. It can track your activity including your keystrokes, steal your credit card numbers, uncover your passwords, and access other sorts of other personal information.

Can mobile devices get spyware?

Like other devices, phones are susceptible to viruses and other malware. One recent notable example is Pegasus spyware, which can be secretly installed on phones and read text messages, eavesdrop on calls, harvest passwords, and even track the user’s physical location. Detect and remove threats with a malware removal tool, and protect your device with mobile security or dedicated iOS security.
