We just received a new worm spreading via MSN from a friend. The file name is "summer2008.zip". In the zip file, it contains a .scr file "summer2008.scr". This worm also can send out different messages with multiple languages. It also adds the Chinese language pronunciation this time. Kaspersky detects it as Backdoor.Win32.IRCBot.acd (old name: IRC-Worm.Win32.Agent.a)

I must admit,

i was a stupid idiot who unknowingly acepted the virus about 7 months ago.
However i have Mcafe and its brilliant.
It detected the virus and ran a scan and got rid of it straight away.

I was extremely scared that id lose all my files and things,But i didnt and it all worked out fine.

Im now aware of he virus and decided to research it because i know that a few friends have it but stupidly enough dont have internet security/
.

Thankyou, for spreading knowledge. ;;xO

i tried the regedit and can't find the entry either
i have followed the instructions concerning stopping auto restore and do a scan and reboot and scan.  i thought i had fixed it but i just had msn on again and it opened multiple windows and closed them like it was sending messages and i had a hard time exiting msn - it said that it would close all active windows but i didnt have any open... so i think i still have it.  any more suggestions??? i have scanned for all of the files you have listed.
thks
