Greeting all. B4 I write my post, Thank to all of u for time and advise.
I found this site bout sub 7. here it is http://www.tlsecurity.net/backdoor/subseven21.htm so isn;t a good idea to download and play with it. I'm quite curios bout sub 7 and may be playing with it can give me more information bout it. But I'm afraid it may ruin my system and as far as I concern sub 7 is the sacriest trojan i ever had. am I right.

So any advice would be appreciate.
