  • Failure to change passwords frequently enough
  • Failure to create completely different passwords for every app/service/site
  • Failure to dream up sufficiently secure/complex alphanumeric combinations

  • All of the above

What happens when you get hacked?

Password breaches lead to direct access to your:

  • Bank account numbers
  • PINs
  • Social Security number
  • Credit card accounts
  • Home address and present location
  • Income tax data
  • Social media and email accounts
  • Other passwords

System Shield

VB100-certified antivirus protection

Block Malware

System Shield is a VB100-certified anti-malware solution that deploys both reactive and proactive malware detection strategies.

A reactive strategy detects viruses using published malware signature detection.

A proactive strategy uses sophisticated behavior-monitoring techniques to build a general sense of whether a given file intends to harm your computer, stopping attacks before a security patch for a particular threat is released.

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.

Malware Killer

Discover and Remove Dangerous Malware Faster

Find and Destroy Existing Malware

Malware is a rapidly growing threat today as almost one million new viruses, worms, Trojans, rootkits and species of spy- and ransomware are released daily.*

Yet most anti-malware software on the market only blocks malware and has no way to remove it from a computer once infected. Several antivirus manufacturers instead even direct customers to costly premium phone support to help remove malware remotely.

Malware Killer is the nuclear option that finds and removes dangerous malware from already-infected computers.

Malware Killer is unique among malware remediation software because it uses proprietary Scan Cloud™-based scanning and analysis, enabled by its own carefully developed heuristics algorithm to dramatically reduce detection time for brand new outbreaks. This method allows Malware Killer to continually add to a vast “reputation database,” and even detect previously unknown threats.

Cloud-Based Malware Detection

Whenever Malware Killer finds suspicious samples, it sends them to the Scan Cloud Sandbox where they are safely analyzed, after which the malware detection engine is immediately made all the more powerful. Malware Killer then shares this increased detectability with all of its users, even on machines where the Scan Cloud functionality is turned off.

Advanced, on-demand malware removal features:

  • Cloud-based malware analysis and remediation
  • Eradicates newest types of malware
  • Fast detection time for latest threat outbreaks

Your AV protection is like the pest traps that keep invaders out. Malware Killer is the home visit from the Exterminator.

Discover and remove dangerous malware with Malware Killer.
