How Do I — Run a Full Scan in PC Matic — to Detect Hidden Threats Properly —

To run a full scan in PC Matic, open the application, make sure it is updated with the latest malware definitions, choose the full system scan option, and allow the scan to complete without interruption. A full scan examines your entire computer—including system files, installed applications, startup locations, and storage drives—to help detect hidden malware, unwanted programs, and other security risks that may not be found during a quick scan.

Keeping your computer secure requires more than simply installing antivirus software. Even if your PC appears to be running normally, hidden threats such as spyware, ransomware, rootkits, and potentially unwanted applications can remain unnoticed without a thorough system scan. PC Matic includes a full scan feature designed to inspect your entire computer for suspicious files, unauthorized software, and security vulnerabilities. Running a full scan regularly helps identify threats before they affect system performance, personal information, or important files.

What Is a Full Scan in PC Matic?

A full scan is a comprehensive security check that examines nearly every accessible area of your computer instead of focusing only on the most common malware locations.

Unlike a quick scan, which primarily checks memory, startup programs, and frequently targeted folders, a full scan performs a much deeper inspection of your system.

During a full scan, PC Matic may analyze:

• Windows system files
• Installed applications
• Startup entries
• Local hard drives
• External storage devices
• Temporary files
• Download folders
• User documents
• Registry-related security checks
• Running processes

Because more files are inspected, a full scan usually takes longer than a quick scan.

Why Should You Run a Full Scan?

A full scan provides broader protection by searching areas where malicious software may remain hidden.

Running a complete scan can help:

• Detect malware
• Identify spyware
• Find ransomware-related files
• Discover potentially unwanted applications
• Locate suspicious startup programs
• Check inactive files
• Verify important system areas
• Improve overall system security

Even if your computer appears healthy, periodic full scans help ensure that hidden threats are not overlooked.

When Should You Perform a Full Scan?

Although every computer is used differently, a full scan is especially useful in situations such as:

• After downloading unfamiliar software
• Following suspicious email attachments
• When your PC suddenly becomes slow
• If unusual pop-up windows appear
• After visiting questionable websites
• Following a malware warning
• Before backing up important files
• After connecting external storage devices
• As part of regular security maintenance

Routine scanning improves long-term protection.

How to Run a Full Scan in PC Matic

Running a complete system scan is straightforward once the software is properly installed and updated.

1. Open PC Matic

Launch the PC Matic application from your desktop or Start menu.

Allow the program to finish loading before starting a scan.

If prompted to install updates, complete them first.

2. Update the Security Database

Before scanning, ensure PC Matic has the latest protection updates.

Current updates help the software recognize:

• Newly discovered malware
• Emerging ransomware
• Updated threat signatures

Follow the software's recommended guidance to complete the cleanup process.

8. Restart Your Computer if Requested

Some security changes require Windows to restart before they take effect.

If prompted:

• Save your work.
• Restart your computer.
• Allow protection services to initialize.

Restarting helps finalize malware removal when necessary.

How Long Does a Full Scan Take?

There is no fixed scan time because every computer is different.

Factors affecting scan duration include:

• Number of stored files
• Drive size
• SSD versus traditional hard drive
• Processor speed
• Available RAM
• Background applications
• External drives connected during scanning

The first scan often takes longer because every accessible file is inspected.

Future scans may complete more quickly depending on system changes.

Will a Full Scan Slow Down My Computer?

Possibly.

During scanning, PC Matic uses system resources to analyze files and monitor storage activity.

You may notice:

• Higher CPU usage
• Increased disk activity
• Slightly slower application performance

These effects are temporary and usually disappear once the scan finishes.

Scheduling scans during idle hours minimizes interruptions.

Should You Run a Quick Scan or Full Scan?

Both scan types serve different purposes.

A quick scan is useful for:

• Daily protection
• Routine security checks
• Fast system verification

A full scan is better when:

• Performance problems appear
• New software has been installed
• External drives have been connected
• You want maximum security coverage

Many users combine frequent quick scans with periodic full scans for balanced protection.

Can a Full Scan Detect Hidden Malware?

Yes.

A complete system scan searches areas that may not be included in a quick scan.

This includes:

• Archived files
• Less frequently accessed folders
• Installed applications
• Startup locations
• Entire storage drives

Although no antivirus can guarantee detection of every threat, a full scan provides the most comprehensive inspection available within the software.

Should External Drives Be Scanned?

Yes, especially if they have been connected to multiple computers.

USB drives and external hard drives can contain:

• Malware
• Worms
• Hidden executable files
• Infected documents

Scanning removable storage helps prevent threats from spreading between devices.

Can Malware Hide From Antivirus Software?

Some advanced malware attempts to avoid detection by hiding within system files or disguising its activity.

Modern security software continuously improves detection techniques, and keeping PC Matic updated increases its ability to recognize newer threats.

Running regular full scans provides an additional layer of protection.
