Using Kaspersky's Online Virus Scan
The Kaspersky online virus scan website http://www.kaspersky.com/virusscanner offers a trial version of Kaspersky Internet Security 2011 instead of the free Kaspersky antivirus online virus scan service. If you really want to scan the computer using the free online scanner by Kaspersky, you should visit Kaspersky web scan webpage instead which is located in http://www.kaspersky.com/kos/eng/partner/200015205/kavwebscan.html
The said Kaspersky online scan is exactly the same as the previous version. Kasperky is planning to upgrade the free online virus scan service but you can still use it, using the above link. The system requirement to run the online virus scan by Kaspersky is by using Internet Explorer 6 and higher, Opera 9 and higher or Firefox 2 and higher versions. Sun Java Runtime Environment plugin is also a requirement.
Using Kaspersky Online Scanner
When the webpage of Kaspersky online scanner opens, it will check the system information and provide a message, if the requirements is not available e.g. if Java RE is not installed:
If you have the required browser and Sun Java RE, the online scanner lets you accept or decline on the End-user license agreement (EULA) in using the free online service by Kaspersky. After agreeing with the EULA, the online scanner will immediately download the program and virus database. It will take some time to download the necessary files if you are not using a fast Internet connection. When it finished downloading the necessary files to proceed scanning the computer for viruses and other types of malware, the scan option will be ready, allowing you to run a critical, full or custom scan:
Tip: Before selecting any of the available scan method in Kaspersky online scanner, you should review the "Settings" by clicking it in the left-hand corner and then select what type of threats to find by Kaspersky antivirus or if you want it to scan email databases and archived files.
Warning: Note that the digital signature by Kaspersky Online scanner is trusted but Internet Explorer will report its status as an "expired" digital signature. Use the service at your own risk but since the connection is confirmed valid to and from Kaspersky server, it is safe to use. jreport is part of Kaspersky Online Scanner which is required to "run" if you prefer using this service that is currently being updated by Kaspersky. It is recommended or best using the supported online virus scanners by other vendors, until Kaspersky has finished upgrading the service.
