How to Scan a File for Viruses and Malware in Power Automate
5/11/2023 - Brian O'Neill

Did you know that you can scan any file upload for viruses and malware in Power Automate using the Cloudmersive Virus Scan Connector?

All you need to do is incorporate the Cloudmersive Scan a File action into your flow diagram, and you can instantly check files against a list of more than 17 million virus and malware signatures, with protection against ransomware, spyware, trojans, and more.

Like most operations in Power Automate, this action is very easy to incorporate. Below, we’ll walk through how you can find, configure, and test the Cloudmersive Virus Scan Connector’s “Scan a file for viruses” action in a simple, instant cloud flow (this flow logic works the same way in automated flows).

From the flow diagram page, let’s start by adding an example file. We can click “New Step” and use a “Get File Content” action to retrieve the file we want. This file for this demonstration is located OneDrive for Business:

1 - Get File Content

Once the "Get File Content" action is open, we can supply our file via the file picker.

2 - Get File Content + File ID

Now that we have our demonstration file within our flow, we can incorporate the Cloudmersive Virus Scan Connector action.

To find the right Connector, let’s click “New Step” again and type “Cloudmersive” into the search bar. Once we do that, a list of Cloudmersive Connectors will populate below our search.

3 - Search for Cloudmersive Virus Scan Connector

From this list, we can go ahead and select the Cloudmersive Virus Scan Connector on the bottom row all the way to the right.

Doing so will prompt us to provide a Cloudmersive API key for authentication. To get your API key, head to the Account Management center in your Cloudmersive account, click “View and Manage Keys,” and then copy your API key to your clipboard. If you don’t currently have an API key, you can get one for free by registering a free account (with zero commitments).

Once our API key is entered, we’ll jump to the Virus Scan Connector actions list.

4 - Virus Scan Connector Actions List

From this list, we can select the “Scan a file for viruses” action at the top.

Doing so will open the connector action body, where we’ll find a prompt to include the input file we want to scan. We can configure this mandatory parameter by clicking on the “input file” field and selecting our file’s content from the Dynamic Content Window.

5 - Scan a File for Viruses Action with File Content

At this point, we can save our flow, confirm our connections, and run our test file through the connector action.

6 - Successful Flow Test Run

When we open the “Scan a file for viruses” action response body, we’ll see our CleanResult response in the action’s Outputs.

7 - Scan a File for Viruses Response Body

We can now use the CleanResult response to dictate subsequent actions in our flow, such as deleting or quarantining our file if any viruses or malware are found.

That’s all there is to it – now you can add a quick, easy layer of security to any flow.
