What Is Malware?

Virus Programs
Viruses are among the oldest forms of malware. They attach to files and spread between systems, leading to data loss and slow device performance.

Trojans (Disguised Threats)
Trojans appear to be useful programs but cause harm once installed. They often focus on stealing passwords and sensitive information.

This variant locks your files and demands payment to unlock them. Without proper precautions, it can result in major financial loss.

How Threats Reach Your Device
