[HLUG] clamav virus protection - is it working?

Hi,

A good virus sender site is:

http://www.declude.com/Articles.asp?ID=99

This allows you to send a variety of Eicar files encoded in different
formats - not all virus checkers will be able to look at all the formats,
but the majority should test OK.

There is also a spam tester, but it isn't really designed for Spamassassin.

Thanks.
Andrew.

Hi John,

I checked the web site and created an antivirus test file eicar.com,
sent it to myself and the filter calling clamscan picked it up and put
it in the virus folder. So it works. Great.

Regards

Gordon
