Hi there!

I went through many other threads and realized that there are some procedures that I can perform myself, but in the end, still need some guidance from all you experts out there.

Avast 4 Home edition is giving me following warnings:

11/26/2008 9:25:28 PM 3916 Sign of "Win32:Trojan-gen {Other}" has been found in "c:\windows\system32\iifghawu.dll" file.
11/26/2008 9:27:28 PM 3916 Sign of "Win32:Zbot-ABD [Trj]" has been found in "c:\windows\system32\ntos.exe" file.
11/26/2008 9:28:05 PM 3916 Sign of "Win32:Adware-gen [Adw]" has been found in "c:\windows\system32\vtuoopjk.dll" file.
11/26/2008 9:30:45 PM 1204 Function setifaceUpdatePackages() has failed. Return code is 0x20000004, dwRes is 20000004.
11/26/2008 9:37:28 PM 464 aswServ::AavmStart ERROR...

Since these are .dll files I do not know if deleting them is the right option. I am not sure how deleting these .dll files might affect Windows operations.

Also to give a background, few months back, whenever I did a search and clicked on the link it would take me to some random page but never to the page linked to the search result. Always on the second attempt, I would be taken to the relevant site. Since last few days, pages keep popping up at random and I suspected I needed to clean things up.

As with all other cases, I am also giving below my HijackThis log:
