What is PC Matic Home Security?
PC Matic Home Security is whitelist-based malware protection for personal computers, built around the SuperShield engine. This page explains the core concepts in plain terms.
Application Whitelisting
Only programs verified as safe are allowed to run by default; unrecognized programs are held back until reviewed.
Fileless Malware Blocking
Aims to detect malicious behavior in scripts and processes that don't rely on a traditional downloaded file.
Dark Web Monitoring
Alerts if personal information associated with your account appears to be part of an online data leak.
Automated Patching
Helps identify and apply updates for common software vulnerabilities.
Ransomware Prevention
The whitelist approach is intended to stop unrecognized ransomware from executing in the first place.
Optimization Tools
Some plans bundle basic PC cleanup tools alongside the core security features.
Common setup questions
Install the software
Download and install the application on the computer you want to protect.
Let the initial scan complete
The first scan compares installed programs against the whitelist and may take some time.
Review any blocked programs
If a trusted program is blocked, it can typically be manually approved.
Keep the software updated
Updates help keep the whitelist database and detection features current.

Home Security FAQ
Why does whitelisting sometimes block programs I trust?
Because whitelisting defaults to blocking anything not yet verified, newly installed or less common programs can sometimes be flagged until they're reviewed or manually approved.
Does whitelisting replace the need for careful downloading habits?
No. Whitelisting is one layer of protection; it's still worth being cautious about where you download software from.
Can I turn off whitelisting if it's too disruptive?
Many whitelist-based tools allow adjusting or disabling the feature, which generally shifts protection toward a more traditional detection approach instead.
