Finds and fixes over 30,000 different issues using intelligent live updates from iolo Labs™ to keep your PC stable and issue-free.

Remove Bloatware

Identifies unwanted startup programs that slow you down by launching and running without your knowledge.

Protects Privacy and Security

Safely wipes sensitive browsing history and patches Windows security vulnerabilities that can harm your computer. 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.

 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.

 Unleash Internet Speed

Automatically optimizes hidden Windows Internet settings for faster downloads, snappier page loads, less buffering, improved video quality and smoother gaming.

Cleans Out Clutter

Removes over 50 types of hidden junk files to free up valuable disk space and make more room for your documents, movies, music and photos.

Safeguard Passwords and Credit Cards

Included within System Mechanic Ultimate Defense, ByePass simplifies your digital life while securing it. ByePass is a platform-agnostic, secure password manager that also helps protect your online purchases.

With ByePass, malicious intermediaries are also thwarted from stealing your credit card info because the numbers are locally encrypted and only deployed as needed to make purchases.

Never again will you need to insecurely type or store passwords and credit cards in your web browser where keyloggers and hackers can steal them. Prevent Windows Slowdown

The eight-time winner of the PC Magazine Editors’ Choice Award, System Mechanic is the only performance solution that first deploys a series of complex automated maintenance actions to help keep your PC stable and clutter-free.

System Mechanic then goes to work using proprietary technology to precision-tune dozens of internet, processor, memory and hard drive settings in real time for maximum system speed and performance.

Recover Lost Data

Search and Recover deploys powerful technology to retrieve items many other file-recovery products miss. Rescue critical work and cherished memories you thought were lost for good.

Get back accidentally deleted documents, music, photos, email, videos, system files and even entire folders from many types of hard drives, cameras and other devices.

Permanently Erase Sensitive Data

DriveScrubber safely and permanently deletes sensitive data from entire hard drives with military-grade file deletion technology.

Threats to your privacy and security come in many forms. One way is when users fail to eradicate their personal information when selling, donating or recycling a computer.

On the other hand, malware signature detection allows System Shield to act reactively. It automatically detects viruses using an established model of malware signature.

Moreover, System Shield is VB-100 certified which indicates that it adheres to the latest malware protection standards.

Malware Killer

As previously mentioned, malware is one of the biggest online security threats. And System Mechanic Ultimate Defense’s Malware Killer detects and destroys all the malware on your computer, regardless if it’s a worm, Trojan, or virus.

Unlike other anti-malware software, Malware Killer uses Scan Cloud to analyze and scan potential threats. Each potential threat is directed to the Scan Cloud Sandbox for secure analysis. This feature allows Malware Killer to operate faster and more efficiently.

System Mechanic

Deleting sensitive data from your PC or reformatting your hard drive doesn’t mean the data is safe from sophisticated thieves. The thieves can still get hold of your emails, pictures, bank statements, and even credit card numbers.
