Note: When using this service for the first time, you have to run with Administrator privileges in order to install the product. Also, you will need to download and install files about 400 KB in size followed by 9 MB of virus definitions. However, if you use the Online Scanner again, you will only need to download the files that have been updated since your last scan. The Online Scanner service offered by Kaspersky Lab uses Microsoft ActiveX technology. Microsoft ActiveX Technology and the Kaspersky Online Scanner work only with MS Internet Explorer 6.0 or higher. The free Kaspersky Online Scanner does not scan boot sectors and MBRs, so it cannot detect malicious code located in these areas. The free Kaspersky Online Scanner does not protect against malicious code, and cannot prevent future infections. It only detects malware that has already penetrated your computer. We strongly recommend that you install a full antivirus solution to protect your system.
