Hi Impact247,
You’ve obviously cleaned out a lot of malware, judging from the avast! log!
A lot of it seems to have been hiding in temp files, and the dialer you mention is still lurking in the same place.
So first I recommend a thorough purge of temp files: download and run CleanUp! and if requested to reboot to allow deletion of some temp files, do so.

If you haven’t done so already, download install and update these two programs: Ad-Aware and Spybot Search & Destroy.

Update AVG Anti-Spyware and boot into safe mode:

Run scans with all three programs.
Reboot and run another scan with HijackThis! If the following entries are still there, tick the box next to the entries and have HijackThis! fix them:
O2 - BHO: (no name) - {15C09A6A-B215-20EC-B472-07E15B54AB68} - C:\WINDOWS\system32\wnyjvbb.dll
O2 - BHO: SurfMatch - {5EA18C9B-8A38-4b15-B196-AEFCB48F4B5D} - (no file)
O4 - HKLM..\Run: [ocnzpve.dll] C:\WINDOWS\system32\rundll32.exe C:\WINDOWS\system32\ocnzpve.dll,aveopkd
O20 - Winlogon Notify: winwea32 - C:\WINDOWS\SYSTEM32\winwea32.dll
Reboot into safe mode and delete these files if you can find them (you may need to enable ‘view hidden files and folders’ in the tools>folder options tab of explorer:
C:\WINDOWS\system32\ocnzpve.dll
C:\WINDOWS\SYSTEM32\winwea32.dll
Finally, run another scan with HijackThis! and post it so we can check that no malware remains, or recommend a further course of action if any malware survives!
