Panda NanoScan

Did you know about this? It's an online scanner from Panda, but unlike some online scanners this one just takes a minute or two.

It claims to detect more than 1,031,124 virus's and spyware.

You do need to download and install an ActiveX to run it and therefore Internet Explorer is recomended, although if it's Firefox or nothing for you then you can install the IEtab addon to run it.

Nanoscan only detects and it's recomended that you run TotalScan if anything is found.
Here is the science bit .

Don't forget, there are other online scanners available and you should always have an active and up to date resident anti virus program on your system.
