Here is a quick way to scan computers online using Mozilla Firefox for any malware or viruses.
1.Go to Bit Defender’s free scanner page.
2. Click on “Start Scanner”
3. Select “Scan Now”
4. A pop up window will be displayed asking whether Bitdefender app should be allowed. (This is basically an add-on/plugin which needs to be installed for different browsers. This example uses Firefox for the scan.)
For Firefox, Select “Allow” and restart Firefox when prompted.
For Internet Explorer, select “Install”.
For Google Chrome / Chromium, select “Continue”.
5. For Firefox, a red circle will now be visible in browser address bar. Click it and accept the EULA for the scan to begin.
6. Wait for the scan to be over (takes only a minute or two) for results to be displayed. Click on the “View Report” link for a detailed report of scanned items.
If there is no antivirus protection installed currently for the computer, download the free Bitdefender suite which is shown at end of scan if needed.
