Hi John,
Do you believe it? I am an avid reader of this forum, I open every message
including the "Happy 1999". The moment I opened it and saw the beautiful
fireworks that has nothing to do with sharechat, I know I'm in trouble!!!!
The next message from Will clearly confirmed that my files are now infected
by those Trojan. My heart sank in the same way as if I saw the share prices
turning down against you.
Thanks to John Redgrave, I quickly follow the instructions to make sure
whether my files were infected.
Yes, I got the first 2 files out these 4 files::
and perhaps

I've cleared them all, thanks again to John.
I'm now sending my message back to sharechat as a test that I'm now free of
Oh, oh, what an experience, I can now say what an excellent forum, and what
a lovely group we all are.

>How can I avoid happy99.exe?
>As a general precaution, you should NEVER run an .exe attachment to e-mail,
