It pretty much works like other web services of its kind like Virus Total by providing an upload form on the website which can be used by the user to upload a file to the service. The file will be analyzed on the web server using multiple anti-virus engines and a report generated in the end that displays information about the scan.

The file upload limit of No Virus Thanks is 20 Megabytes which means that it is not possible to upload files larger than that. The site has a rather low queue of 30 items and displays the current queue number in the upload form. It usually does not take long to process an upload though. The status is shown after uploading the file to the online virus scanner.

The report contains a detailed analysis of the uploaded file including results of each antivirus engine that has been used to scan the file. One interesting option of the online virus scanner is the option to paste a MD5 hash into a form on the website. This can reduce the time before a result will be displayed if the file has already been uploaded and analyzed by another user of the service.

You can also check the article about online virus scanners that lists several websites that will scan the computer with one antivirus engine usually provided by the software developer of antivirus software.

The offer itself is interesting. You do get a free license of CA Anti-virus 2008 that can be installed on three computers. This package usually retails for $39.99.

CA Anti-virus 2008 detects viruses, trojans and worms but not spyware and rootkits. It’s currently compatible to the 32-bit editions of Windows 2000, XP and Windows Vista.

Here is what you need to do to get your free license. Visit the promo homepage and fill out your registration details. The page is in German, enter the following details from top to bottom: First Name, Last Name, Country, Email, Email Repeat, Password, Password Repeat. A click on Senden submits the form and an email will be dispatched that contains a link to the download page that also contains the serial number.

The download button on that page links to the German version of CA Anti-virus 2008, if you prefer a different version use the following links : English, Spanish, French, Italian, Japanese, Portuguese and two unidentified languages abbreviated tc and sc. The second is most likely Simplified Chinese.

I tested the license key with the English version which accepted it without problems.

One major advantage of Virus Total over a single antivirus solution installed on the user’s pc is the fact that it uses almost every known antivirus engine to scan the files which could not be done on a single system because those applications would surely interfere with each other.

The guys from Virus Total have created a file uploader that makes the whole process comfortable. The 80 Kilobyte application installs itself in the right-click context menu as a Send To entry which in effect means that you can right-click a file on your computer and select Send To > Virus Total to send it to their website to scan the file.

A browser window will open displaying the scan results in the end. This is way more comfortable than to open the Virus Total website and browse for the file on your hard drive once you are there.

The file size limitation of ten Megabytes is still in place however. Another option that you might want to explore is to send them files by email [scan@virustotal.com]. A report is send to the email address that you have used to send the file.

Infected or Not from Panda Antivirus however catched my attention by providing interesting statistics about infected computers on a worldwide and country wide scale.

According to their statistics which are updated when scanning computers 10.90% of all PCs scanned were infected. PCs with Antivirus installed had a infection rate of 8.62% while PCs without Antivirus were infected 14.56% of the times.

Infected or Not displays the rate of infected PCs using a Google Maps mashup. France for instance is the country in Europe with the highest amount of infected PCs (16.41%) while Sweden (4.17%) and Germany (5.33%) have the least amount of infections. The United States has an infection rate of 10.34 btw.

The scan works with Firefox after installing an add-on which can only be uninstalled from the default installation location which is at C:\Program Files\Panda Security\NanoScan. Execute the file nanounst.exe to uninstall it again.

Antivir reported a trojan during installation and execution which can be considered a false positive. In case you are wondering why I have Antivir installed, I did not test this from my main computer.

You could try to test your anti-virus program against the EICAR (European Expert Group for IT-Security) test file to see if it reacts the way it should. All you need to do is create the testfile and scan it with your virus scanner. If the scanner detects something it is working as intended, if it does not you should consider changing immediately to a more reliable one.

Creating the file is pretty simple. Just create a new text file and paste the following line of code into it: X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

Save the file and rename it to test.com. When executed it displays the message EICAR-STANDARD-ANTIVIRUS-TEST-FILE. No harm will be done to your system if you accidentally execute the file. To test your virus scanner right-click the file and select to test it with your software.

You could also pack it and test it or send it to your email account to test the interaction between virus scanner and email client. After the test finishes you do know if your virus scanner is working as intended and able to detect viruses on your system. This does not necessarily mean that it will detect every virus that exists but it means that it is working.
