[Our free online virus scanner is a great way to find out if you have any viruses or spyware on your machine without having to install new software. You can also see what viruses your current antivirus software let slip through! You just need to be online and using Internet Explorer.

The Online Virus Scanner uses Java technologies to scan your computer for malware. The free virus scanner scans your machine while online, and uses the same technology as other Kaspersky Lab products. Our antivirus software protects against viruses and spyware. ]
