Hi Lectrik,
Please ensure you have done a thorough scan with avast!, preferably a boot time scan. (Apparently this doesn't work in Win 98: if you have this OS, boot into safe mode before scanning- hit F8 while booting.)
Right click the avast! globe and select Start avast! Antivirus.
avast! will do a memory scan: if it find the worm in memory, it will prompt you to do a boot time scan: accept this and reboot.
If avast! doesn't find anything in memory, schedule a boot time scan. (Click the button at the top left of the avast! silver console and select Schedule boot time scan from the drop-down menu.)
These two powerful anti-Trojan programs are worth a try:
TDS-3 (Download the definitions file and move to the program folder.)
http://tds.diamondcs.com.au/and TrojanHunter
http://www.trojanhunter.com/They both have a free trial, and will find Trojans that anti-virus programs miss.
Ewido is also worth trying: it has a free version:
http://www.ewido.net/en/Please ensure that you have a firewall and that your OS is up to date, otherwise infections will come back.
If you need advice on either of these subjects, please say so.
If you still experience problems, please run HijackThis and post a log file:
