unless you mean that you have 3 instances of svchost.exe running; that's

normal (unfortunately) and about as meaningfull and buggy as rundll(32) at

previous windows versions.

Let me clarify this...

If the file is named "svchost(3).exe" it has a high probability of being malicious.

It is is not the number of instances of svchost.exe running that is important, it is the

path from which it runs.

SVCHOST.EXE (or variations thereof) is the most common name used by malware to obfuscate

the malicious intent.

If the file is executed from %windir%\system32 it has the propensity of being legitimate

(unless trojanized/patched).

If the file is executed in any other location then the chances are extremely high it is

malicious.

If the file is found running under Win98/ME then the chances are extremely high it is

malicious.

This is an illegitimate process...

%windir%\system32\svchost(3).exe

I am surprized that nothing was detected, even a heuristic detection.

Could you please provide me a sample.

Place svchost(3).exe in a password protected ZIP file with the password being; infected

{ password = infected }

And send the file to DLipman~nospam~@Verizon.Net

removing ~nospam~ from trhe above address.
