Troubleshooting Device Infections: When Antivirus Solutions Fall Short

If you’re experiencing persistent issues with your device after lending it out, you’re not alone. A friend recently borrowed my external hard drive, and upon its return, I found myself inundated with notifications from Windows Defender. It was clear that something was amiss.

To tackle the issue, I first attempted to run Malwarebytes, only to discover that it had been removed in what I suspect was a hostile takeover by the malware itself. Frustrated but determined, I turned to the Kaspersky Rescue Disk, which managed to identify numerous threats lurking within my system. However, upon rebooting my device, the same issues resurfaced, leaving me back at square one.

These experiences highlight the challenges many face when dealing with an infected device. It’s crucial to be aware of these potential pitfalls and to take proactive measures for device protection. In this blog post, I’ll share strategies that may help you to effectively manage similar situations and ensure your device remains secure.

  1. It sounds like you’re dealing with a persistent malware infection that is actively resisting removal efforts. In cases like this, I recommend performing the following steps:

    • Boot into Safe Mode with Networking to prevent malware from actively running during removal.
    • Use a reputable Malwarebytes scan in Safe Mode to identify and remove threats. Ensure that the software is up to date before scanning.
    • Consider running a ComboFix or similar advanced removal tool if standard scans are ineffective. Be cautious and research thoroughly before using these tools, as they can be powerful but potentially risky.
    • Reset or reinstall your operating system if the malware persists after multiple removal attempts, as some infections deeply embed themselves in system files.
    • Make sure to regularly update your operating system, antivirus, and anti-malware tools to prevent reinfection.
    • To prevent future infections from external drives, always scan them with a trusted security tool before using them on your main system, and consider implementing write-protection when possible.

    If you continue to experience issues, consulting with a professional cybersecurity specialist may provide more tailored assistance. Stay vigilant
