I run several Yahoo groups (Freegle/freecycle etc), occasionally (and very often these days) a member (usually not a very active one) send
a spam email - like the canadian healthcare one etc.
The member has obviously got all the email addresses of anyone that has mailed her available to spam to
so to prevent any new members or those that the infected members has not already got what we do is simply
remove them from the group, email them telling them why and what they should do (run malwarebytes/change pw etc).
This seems to work quite well, 95% of the time the infected member is no longer interested in the group anyway.
For the 5% that would like to come back in I generally ask them to run Malwarbytes & then Hijackthis and send in the logs
so that they can be looked over for suspicious software etc.
Seems to have worked - It forces them to run some decent software & I get proof that they have done it.
I also ask them to change their email account passwords.
(Most are yahoo or hotmail accounts).
Can you suggest any other actions that I could take to try and protect the rest of the group(s) (4k+ members).
Also, which forum on here should I be posting hijackthis logs into for a 2nd opinion?
