Avira Free Antivirus with Malware Cleaner

What is malware?

Malware is shorthand for malicious software that infects your system. It’s developed by cyber-attackers in order to steal personal data, gain access to your device, or cause damage to it. Rootkits, viruses, trojans, spyware, adware, worms, and browser-hijacks are all malware.

Trojans

sneak into your system, often disguised as a legitimate tool.

Spyware

monitors what you do online.

Ransomware

encrypts the infected system, locking the user out until they pay a ransom.

Keyloggers

log all your keystrokes and give cyber-criminals your login credentials. They can use your identity to access online stores and go on a shopping spree.

Viruses

can infect the operating system and slow it down or stop it from loading altogether.

Avira Free Security

Here’s why we ALL need reliable anti-malware every day

Hackers are continuously finding new ways to steal your data or just wreak havoc. But it’s not just about security… but also preserving your freedom and confidence, and giving you peace of mind. If you surf the internet, browse, bank, shop, or connect devices to your computer or laptop, you risk malware infection every time.

For comprehensive protection:

1. Install antivirus/anti-malware software.

2. Be diligent about keeping that software updated.
