In the previous entry, I reproduced a piece of code used by a Trojan email / website to download programs onto PCs. I put the code in as text to show what the Trojan does.
I completely ignored the possibility that some browsers may execute the code rather than treating it as text (slim but possible) and the much more real possibility that anti-virus programs would pail to differentiate between the text and code to be executed falsely warning that this page contained a virus.
Oops.
If you had that warning, don't worry. Your browser shouldn't have executed the code and you should be OK.
