I beleive I may have a possible Trojan Downloader on my system as there are often multiple batches of spyware found by Spybot Search & Destroy as well as numerous trojans found by NOD32.

One .dll file I am particularly suspicious about is the hgghgec.dll located in the System32 folder. I have tried booting into safe mode but it seems my motherboard prevents this as when I hit F8 I get a "Boot from Device" screen appear asking me which device I would like to boot from, it then proceeds to boot as normal.

The trojan called TROJ_VUNDO.AVZ has been mentioned numerous times but I can not seem to find a fix for it.

My name is Richie and i'll be helping you to fix your problems.

Please download Combofix and save to your desktop:

It is important that it is saved directly to your desktop

Close any open browsers.
Double click on combofix.exe and follow the prompts.
When it's finished it will produce a log.
Post the entire contents of C:\ComboFix.txt into your next reply.

That may cause the program to freeze/hang.
