My computer is infected with virus. I have use combofix.exe to fix it but still cannot.
My computer is infected with Trojan program Trojan-Downloader.Win32 Genome.skj which is detected by Kaspersky 2009.
Thought the infected file is nothing then i had open it in a safe run shared folder then my computer is infected with virus.

After my computer was infected:
Even no program is running the cpu usage is more than 10%.
svchost.exe is running under the user name of bryan(not system or local service).
When i end the process after a few second it come back automatic.
Or when i go online and try to end the process svchost.exe (username bryan) my network usage go back to zero.
I did not download anything or surfing the web and when svchost.exe start(username bryan) the network usage goes up. Usage is around 0.11%). Plus IEXPLORE.EXE running even i did not open the internet explorer.
I have run a full scan with Kaspersky Internet Security 20009 and the database are up to date but unable to detect it.

The virus was downloaded in: (http://server37.cn/crack/crack411.exe) (File size:11.5kb)


Can anyone tell me how to fix it? And what does this virus do?
