Recently my system became infected with WIN32/NSAnti
virus.AVG keeps detecting it evertime I open a drive. the problem keeps reoccuring even if I move it to the virus vault.
I cant seem to open yahoo messenger too and i cant access any hidden files.
I have moved amvo.exe and amvo0.dll to the vault as AVG detects them as viruses.
Plzzz help!!
here is a hijackthis logfile

Hi robben

1. Download combofix from any of these links and save it to Desktop:
Link 1 (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
Link 3 (http://subs.geekstogo.com/ComboFix.exe)

**Note: It is important that it is saved directly to your desktop**

2. Double click combofix.exe & follow the prompts.
3. When finished, it shall produce a log for you (C:\ComboFix.txt). Post that log in your next reply

Note:
Do not mouseclick combofix's window whilst it's running. That may cause it to stall

Combofix should never take more that 20 minutes including the reboot if malware is detected.
If it does, open Task Manager then Processes tab (press ctrl, alt and del at the same time) and end any processes of findstr, find, sed or swreg, then combofix should continue.
If that happened we want to know, and also what process you had to end.

If you have problems with Combofix usage, see here (http://www.bleepingcomputer.com/combofix/how-to-use-combofix)

Post:

- a fresh HijackThis log
- combofix report
