Personally I discounted SpeedyPCs comment as I don't believe we are that far down the road yet.
What did you do about the items I mentioned in my reply #8 in this topic,
http://forum.avast.com/index.php?topic=30139.msg250229#msg250229, did you fix them in HJT, etc. ?
Did you send the files to VirusTotal and Jotti as suggested, you never mentioned if you had ?
Take some time in rereading that post again, there are a number of links for the different entries that you should visit
You should also include in the fix the item mentioned by Maxx_original:
O4 - HKLM\..\Run: [SystemOptimizer] rundll32.exe "C:\WINDOWS\xxxvvw.dll",forkonce
Also I have been rereading the topic and your comment after my reply (link above) had me thinking you want to send the suspect files mentioned in my reply rather than infected files in the chest. The location of the files you get from your HJT log entries that I quoted.
I wan to send the infected files to avast but dont know how to setting the outlook, so it cant b send. Can know how to setting the mail setting when wan to send those files??
Do you connect by dial-up to the internet ?
If not a dialler isn't such a great issue as it can't do what its purpose is, to dial premium rate number to connect to the internet rather than your ISPs dial-up number. But, we still want to get rid of it.
How is it attacking your PC, do you simply mean it keeps coming back and avast keeps detecting it, or do you mean something more ?
