Check For Malware And Adware

🪲 Check for Malware and Adware

This procedure outlines the necessary steps for running full system scans and checking for common browser hijacks.


I. Windows Secutity Check & Clean-up

Run FULL scans using the following tools to detect and remove common malware, adware, and potentially unwanted programs (PUPs):

  • ADWCleaner
  • Malwarebytes Antimalware
  • Local AV (Antivirus software already installed on the system)

If the system is badly infected, run a FULL scan with:

  • Spybot Search and Destroy

Advanced Malware Cleaning Tools (For Heavily Infected Systems)

For persistent or severe infections, consider using these specialized tools:


II. macOS: Malware and Antivirus Tools (ClamXAV or MBAM)

Macs are vulnerable to adware and PUPs. Use the following tools to detect and remove Mac-specific threats.

1. Malwarebytes for Mac (MBAM)

  • Action: Download the official installer for Malwarebytes for Mac.
  • Procedure: Install and run a Full Scan. This is highly effective at finding macOS-specific adware, PUPs, and browser hijackers that may not be caught by generic Windows tools.

2. ClamXAV

  • Action: Download and install ClamXAV.
  • Procedure: Open the application and navigate to the Source List to select the appropriate items for scanning (e.g., the User Folder or the entire Macintosh HD). Run a Full Scan.
  • Note: ClamXAV uses the open-source ClamAV engine and is particularly strong at detecting malware (including Windows malware files stored on the Mac) and is often preferred for its lightweight resource usage.

III. 🌐 Browser Hijack Checks

Check all installed web browsers (Chrome, Firefox, Edge, Safari, etc.) for the following common issues, which often indicate adware or malicious extensions.

  • Check 1: Malicious Extensions:
    • Action: Navigate to the browser’s Extension/Add-on Manager. Remove any unexpected, unwanted, or suspicious extensions. If in doubt, disable or remove it.
  • Check 2: Search Engine Hijacks:
    • Action: Check the browser’s Settings or Preferences for the Default Search Engine. Reset it to the desired provider (Google, Bing, etc.) and remove any malicious entries.
  • Check 3: Start Page Hijacks:
    • Action: Check the browser’s settings for the Home Page or Start-up Page. Ensure it is set to a blank page or a legitimate site.
  • Check 4: Notification Hijacks:
    • Action: Check the browser’s Site Permissions or Privacy/Security Settings for Notifications. Revoke permissions for any suspicious websites that are spamming the user with pop-ups.
  • Check 5: Run a scan with ADWCleaner:
    • Action: Download and run a scan with ADWCleanr. It goes after adware, spyware, potentially unwanted programs (PUPs), and browser hijackers. It is specially engineered to remove these types of threats.
