Free Online Virus Scanner
Many Internet security companies offer free online virus scanners. These normally run via a plug-in from the website, and you can search for them online. Unless you know and trust the name of the vendor whose service you are using, I recommend using one of the following vendors.


  • Trend Micro houseCall

  • BitDefender Online Scanner

  • ESET Online Scanner

  • Kaspersky Online Scanner

  • Panda ActiveScan



These free online services are very efficient and competent. However, they are not a substitute for a full anti-virus package, since they will commonly be able to scan for only the biggest and most well-known viruses, not the full range of viruses that your own anti-virus software can scan for.
