One of the first questions we will ask, have you saved your important files to an external hard drive or cloud service? This protects your work if the computer breaks.

PPCS will Research, Install and Scan your System/device with a trusted antivirus program. Run scans often to find and delete harmful files.

PPCS IT technician follows a structured lifecycle to manage, maintain, and troubleshoot antivirus and malware systems in your home, or across an enterprise network. These processes were in my “Continuity Book” when I was a “Break-Fix /Service Center/Help Desk Technician for a multitude of Federal agencies and private-sector organization.

1. Preparation & Baseline Setup

• Deploy agents: Install lightweight endpoint detection and response (EDR) or antivirus agents on all network devices.

• Define policies: Set scanning schedules, exclusion lists, and real-time protection parameters based on user roles.

• Configure updates: Establish automated schedules for virus definition files and engine updates to ensure zero-day protection.

• Integrate logging: Connect endpoint logs to a Centralized Security Information and Event Management (SIEM) system.

2. Monitoring & Detection

• Analyze alerts: Monitor central management consoles for high-priority security flags and anomalies.

• Review logs: Scan system logs for unauthorized access attempts, disabled security software, or failed updates.

• Run scans: Execute periodic full-system scans during off-peak hours to catch latent threats.

• Track compliance: Identify unprotected, rogue, or out-of-date devices connecting to the network.

3. Containment & Triage

• Isolate devices: Disconnect infected machines from the local network and Wi-Fi immediately to prevent lateral movement.

• Kill processes: Terminate malicious active processes via command line or security consoles.

• Preserve evidence: Take volatile memory dumps or snapshots if forensic analysis is required for legal or compliance reasons.

• Notify stakeholders: Alert the security team and affected users according to the company's incident response plan.

4. Eradication & Remediation

• Remove threats: Quarantine or permanently delete detected malicious files through the antivirus interface.

• Boot safely: Run specialized offline scanners or boot into Safe Mode if persistent malware resists standard removal.

• Clean registries: Repair compromised system files, host files, and registry keys altered by the malware.

• Reimage systems: Wipe and reinstall the operating system from a clean baseline image if infection depth is uncertain.

5. Recovery & Post-Incident Review

• Restore data: Recover lost user files from verified, clean backup sources.

• Verify health: Perform exhaustive follow-up scans before reconnecting the device to the production network.

• Patch vulnerabilities: Update the OS, applications, and firmware to close the security gap that allowed the exploit.

• Document lessons: Record the root cause, response times, and system vulnerabilities to update future security protocols.

Keep your operating system (like Windows or macOS) and apps up to date. Updates fix security holes and bugs.

Use built-in tools to delete temporary files and junk data. This frees up storage space. We prefer to use our own PowerShell scripts for task like this.

Reorganize traditional hard disk drives (HDDs) to speed up file loading.

We do not do this for solid-state drives (SSDs).

Built-in Windows Tools:

Optimize Drives App: "Defragment and Optimize Drives" in your Start menu, select your SSD, and click Optimize to run a manual scan

Wipe dust away from vents, fans, screens, and keyboards. Use compressed air for tight spaces.
