I, and a number of others, were getting warnings when trying to access my web site http://www.wa2ise.com for the last couple of weeks. I FTPed to my web host, and according to the dates at the ftp site, something happened to all my html files on Jan 20, 2013 around 9PM. I copied the index.html file to my 1st computer (I have MacFee SW on it), it reports that it found, then removed a Trojan embedded in this file. As a test, I copied this cleansed file back to the web host, and tried on my 2nd computer (running Norton) to look at my web site. It used to be rejected, now it loads as normal.

Then I did the rest of the html files, and when I copied the various html files to my computer, McAfee says it found a trojan in each file, and removed it from each file for me. I then copied these "cleansed" files back to the web site via ftp, and my 2nd computer, which used to deny access to my web page, now doesn't get upset, and it now loads as normal.

So give my web site another try. Looks like the trojan is gone, I hope...

If you still have a copy of any of the infected files it might be interesting to upload it to VirusTotal and see what the suite of virus checkers make of it:

Found another problem, this one my mistake: I uploaded the wrong index.html file to my web site's root directory. But I corrected that this morning USA time.

Looked at the MacAfee logs, and it says that trojan was this:
JS/Exploit-Blacole.gc

For those running Norton Internet Security, there is a glitch (Error Message 8504, 104) which disables this program recently. You have to go to the Symantec web site and load the patch. I have caught this recent Trojan 3 times with Norton. Others were not so lucky.
If you do not have a good anti-virus program fully updated daily you leave yourself open to attack. No anti-virus is 100% safe against the bad guys.

I use Avast! (the paid-for version). It has saved my bacon on many occasions.
