Detect Viruses and Spyware with our Online Scanner
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.
This free online virus scanner is very powerful and scans your machine very deeply, so it could take hours to complete. We suggest running it during a time of low activity. Take the Kaspersky Challenge and see what malware your current antivirus software missed - you may be surprised.

NOTE: The online virus scanner will not remove the malware from your machine if it finds it - installing our software is required to do this. You can try our antivirus software (full product) for FREE by downloading and installing a free trial, or you can purchase our products in the estore.
If you discover a suspicious file on your PC, or suspect that a program you downloaded from the Internet might contain malicious code, you can check the files using the free Kaspersky File Scanner. Using Kaspersky® Anti-Virus technology, any file you send to Kaspersky Lab will be checked for viruses, Trojans, spyware or other crimeware or malicious code.
