Brace yourself....dev's explanation is coming
Sooo...S-bot.exe has no virus as you can see. FSbot,palavia and other bots has potential errors...but nevermind.
S-bot autoupdate.....I made this pretty small script for you ...so as not to download newest patch/version manually. +that is the reason....This autoupdate.exe download (without your permission) a new update...so thats why it looks like a virus fot your antivirus program....
to be honest....I dont need your accs...I have UFE
There are my reasons why not to harvest your data.
Because:
1) probably I will get some money from it(ads)
2) I use it and my friends too
3) I have got it as a school project
That is my point of view...If you dont like it...just delete your bot and find another bot without "viruses" !
PS: I am trying to do autoupdate more "cleaner" for antivirust...but as you know...AutoIt+obfustation+script with downloading something=Trojan

I will try to find some solution :P
EDIT
this:

means that I have some mistake in code...so please send me all setting you had on S-bot when it occured....thnx
