Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix


Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.


If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

As you can see, you're infected with ----> Win32/Virut.NBP virus

Here's some info on the virus:

We can try and clean the system but no guaranties, it's advised to wipe the system clean and start over.

If you would like and try to clean the system, start by running by running avg_remover_virut.exe:


Then run virutkiller.exe:


Let me know...MrC

Finish with avg_remover_virut.exe just 1hours ago.
During cure, it say log file in C: can't be open and once restart I open the log file and it just said....




Virus Remover for Win32/Virut version

C:\rmvirut.log                                                                   Can't open

-- EOF --



However, MWB stop show popup blocking outgoing right now. Seem like some of them are cure, but for virut information you given. 1 alive = whole infect, wipe out still waiting for me.


Now try runing with virutkiller.exe. Judge from scaning speed, it may take another 2-3 hours, Even now it still said some file being cure (but judge from number of file cure - look like they're left over from avg as C: only have ~14 exe files cure.
virutkiller.exe say it Virus.Win32.Virut.ce

After finish virutkiller.exe I'll try scan with ESET and report to you again.

Downloading DrWeb Cure-It, it'll take 1 more hours (my connection to other country is pretty slow).

Finish virutkiller.exe scaning. ~ 22 files is cures. I also boot into safemode and re scan with virutkiller.exe (didn't try with avs as the scan take about whole 7-8 hours to complete - I'll try do it during this night). No more cure/infect detect, the virutkiller.exe show 0.

I'll report again once DrWeb Cure-It complete download and scan.

May I ask some about virut?
Yesterday when I spot that I'm infect with (brontok) I try to close most online-relate program. But during cure with MWB some reboot accident leave Hamachi open. It virut possible to infect through network system without using it?

I worry about, will it infect other people in Hamachi room that I join? and also I'm connect to router with lan cable and my father PC also connect to this router with another lan cable. I didn't setup any network share with my father PC. will it possible to infect my father PC?.

Everything seem to be ... clear I guess

Internet access
Windows Update
Windows Firewall


All of them can access, update and turn on/off normally.


I also skim through some my html, php file most of them didn't infect with iframe as virut information had mention. (still looking more on them)

Not sure which thing I should do next to make sure that my PC is clear.
