This is the first in IT Security's periodic list of free security tools. Be aware that these are by no means all the anti-virus tools on the market. For example, this list does not include major anti-virus vendors that provide paid individual and enterprise solutions. However, that does not mean that the included anti-virus tools are not worthwhile — the best of them are as good as paid programs. In the interest of listing tools that can help in a moment of crisis, this list only includes tools that can detect, clean, remove or neutralize viruses. There are also tools to scan a local hard drive, as well as those that can accept a single uploaded file and indicate whether it is infected with a virus. Of course, if a file is small, an easy way to check it for a virus is to send it to yourself via a free email service like Yahoo! Mail, Gmail or Hotmail, which scan all file attachments.
Wherever possible, this list includes just those sites that are the originator and main site for that particular engine. Some online anti-virus scanners have private-labeled their engines to third parties, but these engines are not always up-to-date or as good as the original.
In the future, IT Security will compile a list of free downloadable antivirus tools.

F-Secure Online Scanner : Another scanner that requires IE and ActiveX. It also checks for rootkits.
Panda ActiveScan : Based on the popular Panda virus scanner, the online version also requires IE and ActiveX.
Windows Live OneCare : Microsoft 's online virus scanner is based around its new Windows Live technology — and yes, this service too is only compatible with Internet Explorer with ActiveX controls enabled.
Trend Micro HouseCall : A smarter online scanner than most, Trend Micro 's solution detects browsers and installs the appropriate piece of code needed, whether it's Java or ActiveX. The service is based on TrendMicro's popular anti-virus engine.
Note that leading anti-virus vendors McAfee Inc . and Symantec Corp . have rich online scanning tools, but these services do not actually remove detected threats.
