Antivirus software uninstalled by malware

4.5

You wake up to find your security software is completely gone from your PC.

Symptoms
  • Missing antivirus icon
  • Folder empty
  • Windows Security warning
Possible Causes
  • Malware with high privileges
  • Rogue uninstaller script

Step-by-Step Fix

1

Do NOT Reinstall Yet

The malware will just delete it again.

2

Run Portable Scanner

Use "Kaspersky Virus Removal Tool" which doesn't require installation.

3

Check for Rogue Admin Accounts

Ensure the malware hasn't created a new user with admin rights.

When to See a Technician

If your antivirus is gone, your system is "Compromised". A full wipe is often the only safe solution.
