If your antivirus has detected the presence of the EICAR file
Your antivirus is providing adequate protection against viruses embedded in a web page.
But don't drop your guard completely and make sure your antivirus is always updated against all new strains of viruses. We also recommend that you visit this site regularly to keep well informed.
If your antivirus has not detected anything
Be careful! Your antivirus may be disabled, not updated, improperly configured or you don't have an antivirus. It is very important to have a fully-updated antivirus that adapts to your specific needs. If you would like to download one that best meets your needs, go to 'Free antivirus'.
If your antivirus is configured to function automatically, it may have detected the file without warning you. Go to the antivirus report and see if it has detected the EICAR.COM file as if it was a virus.
If your PC is part of a corporate environment it is possible your antivirus has not detected the EICAR file, even though you are being adequately protected. This could be due to the existence of a firewall or proxy, which could prevent the EICAR file from reaching your PC.
