System Shield

Shield Your PC from Viruses and Dangerous Spyware

Safeguards your PC with real-time antivirus protection
Speeds up and declutters with all the tools in System Mechanic®
Detects the newest malware threats with advanced artificial intelligence
Safely recycles old PCs with military-grade drive wiping technology
Recovers irreplaceable photos, videos and more across many device types
Removes system-hogging bloatware that slows you down

Not long ago cybersecurity teams at several leading anti-malware companies reported that almost 1 million new malware threats are released daily. This astonishing volume of rapidly evolving threats makes it more essential than ever for Windows users to protect their PCs with the best, most up-to-date antivirus software they can find.

Yet according to Verizon’s 2015 Data Breach Investigations Report, in nearly 90% of cases, hackers relied on computer bugs that have been around since 2002. This means that AV software with an established history is as equally important as making sure it is regularly updated with the latest threat definitions.

Since 1998, System Shield has been at the forefront of this fight by regularly and automatically incorporating the latest threat definitions to maintain an ever-expanding roster of both specific malware signatures and suspicious behaviors to help keep your PC safe.

Protect your PC from viruses, spyware, Trojans, rootkits and other malicious software with System Shield.
