IT Essentials – Malware Emergency?


Last week we covered anti-malware options for businesses and individuals – but what can you do if you think there’s a problem, and your computer doesn’t have anti-malware software?


The software we recommend is MalwareBytes anti-malware, and Microsoft’s Malicious Software Removal Tool. For home users, MalwareBytes is free, and very efficient at quarantining and removing threats. It’s important to remember that the free version of this software does not provide any real-time protection and will not stop your machine becoming infected, but it is useful if you suspect there is a problem. Microsoft Malicious Software Removal tool is freely available to all owners of a genuine copy of Windows.

Network administrators can purchase a business version of Malware Bytes for use in an office setting, which is specially built for their business size.

If you suspect there’s a problem with some of your equipment but are not comfortable with running software like MalwareBytes or are unsure of what to do, we recommend that you contact an IT professional or Network Administrator as soon as possible.

The most important thing is that you DO NOT turn off or restart your computer. Doing so could cause further damage.

If you are unsure of any of the steps in the following list, we recommend that you consult an IT professional who can help you out.

When you’ve downloaded MalwareBytes and the Microsoft Malicious Software Removal Tool, you can use these steps to help you remove malicious software from your computer:

  • Disconnect your computer from any networks. Remove the Ethernet cable or turn off/unplug the wireless adapter.
  • Disable System Restore.
  • Run MalwareBytes, choosing a quick scan.
  • Run the Microsoft Malicious Software Removal Tool (MMSRT).
  • Quarantine or remove any threats as suggested by these tools.
  • Restart your computer in safe mode.
  • Repeat the scan with Malware Bytes and MMSRT.
  • Follow any instructions given by these tools, and repeat scans/restart as necessary.
  • Ensure all program patches and security updates are applied, e.g. Windows Update.


Please remember that this information is provided only as a suggestion, and that Geek Guru cannot be held responsible for any damage caused by attempts to follow these instructions. If you are unsure of anything at all, we recommend leaving the work to an IT professional.
