Hi all,
 am a new member to this group.
well, My system is affected with a virus called Soundblaster.exe this virus is sitting in C:Windows/System32.
I scanned using Norton Antivirus , McAfee and also spyware (webroot spysweeper). there is no use to remove the virus from the system.
Then I tried to remove as described in the website

As described in the site i removed the soundblaster.exe file in the TaskManager... no use still itz active
and then as described below from the link

Removing Autostart Entries from the Registry

Removing autostart entries from the registry prevents the malware from executing at startup.

Open Registry Editor. Click Start>Run, type REGEDIT, then press Enter.
In the left panel, double-click the following:
HKEY_LOCAL_MACHINE>Software>Microsoft>
Windows>CurrentVersion>Run
In the right panel, locate and delete the entry:
Micr Update = "soundblaster.exe"

>>>>in my PC There  was no Micr Update = "soundblaster.exe"  entry in the rigistry


In the left panel, double-click the following:
