IMPORTANT UPDATE: Unfortunately the Avast Online Scanner is not available anymore. Instead we recommend using the VirusTotal scan, which is also online and totally free.
Sometimes you may need to scan a file on the computer where Avast antivirus is not installed. In this case Avast Online Scanner will be very handy.
Avast Online Scanner is a free, web-based virus scanner from AVAST. It will scan the uploaded file on the server and display you the result. Detection mechanisms are the same as on the regular, desktop-based Avast antivirus.
Even though the tool’s interface hasn’t been updated for at least two years, the virus definitions are updated automatically every day.
Please note this tool can only scan, not heal or quarantine the file. If Avast Online Scanner detects a virus, we strongly recommend to download the Avast Antivirus on your desktop to gain the full protection.
Avast Online Scanner – Free Web-Based Tool for Online Scanning

Avast Online Scanner – Scan Results
Scan results are displayed almost immediately. You can also check the version of the virus definitions in the ‘VPS version’ row. It should be always matching the current date if the definitions of the Avast Online Scanner are up-to-date.
