Make your old computer run like new. Keep your new computer running fast and problem-free. System Mechanic Pro repairs drive and registry errors, stabilizes your computer, optimizes your internet connection, scrubs sensitive data, and defends against malware and intruders.

The software runs automatically, intelligently cleaning and tuning your entire computer. Or you can launch select tools in System Mechanic Pro whenever you think your system may need a boost. Performance and security tools include registry repair; hard drive, memory, and registry defragging; junk file and file fragment clean-up; application management to reduce overhead; antivirus and firewall protection; true data recovery to restore lost or deleted files; and military-standard file erasure and drive scrubbing.
