Double-click **Avast Business Security** on your desktop

Click **Protection** > **Virus Scans**

If this is the first time you have clicked on Virus Scans, you could see the message Activate real-time scanning advising about all the different ways you can setup scanning to detect hidden threats. Click **GOT IT** once you have finished reading the information.

Click **SCAN NOW** under Full Virus Scan

Depending on the speed of your computer, this can take anywhere from 15 to 45 minutes. You can use your computer while the scan is running and should you wish to, you can tick the box ‘Shut down computer after scan finishes’ should you not want to use the computer afterwards.

If nothing is found, you will see the message 'No malware found' Click **DONE**

The message ‘We were unable to scan some files’ is quite normal, as some files are normally in use by the operating system and cannot be accessed.
