Malware in File "C:\WINDOWS\system32\Process.exe"

I ran Zone Alarm Security spyware detection software last night and it
detected a malware named "Win32.BackDoor.Bifrost" in "C:\WINDOWS
\system32\Process.exe" . The Zone security suite gave me the option
to quarantine the file of to delete the file. I am wondering if the
file it is listed as being in is an actual Win 32 file? Should I
delete the file?

Thanks!

Process.exe does not appear to be a genuine Windows system file.

This is not a Windows XP file. Maybe double check it using Spybot S&D
1.6.

Delete it then restart the computer.
There's no file called process.exe in my system32 folder.

Correct.

However, there *is* a file called qprocess.exe in the system32 folder.

As others have noted, there is NO legitimate PROCESS.EXE in %windir%\system32

If you are unsure...


Please submit a sample to Virus Total --
http://www.virustotal.com/flash/index_en.html
The submission will then be tested against many different AV vendor's scanners.
That will give you an idea what it is and who recognizes it. In addition Virus
Total will provide the sample to all participating vendors.

You can also submit a suspect, one at a time, via the following email URL...
mailto:[email protected]?subject=SCAN

When you get the report, please post back the exact results.

NO !

This is not the correct procedure. SpyBot S&D is limited in scope and will likely produce
a False Negative.

Sending the file to Virus Total is the proper methodology as you would then have your one
sample examined by 33 anti virus scanners providing both heuristics and the wealth of
100's of thousands of signatures per AV vendor.

Were any anti-malware tools used previously that were recommended by a
helper on an anti-malware forum ?
It is not uncommon to include process.exe in said tools.

Give me a break. There are countless dozen utilities for determining
what this baddie is. The user isn't going to do forensics on it. They
want it deleted off their system if it is a threat. False negatives my
posterior.

So? Malware is well noted for selecting file names that resemble
those of genuine Windows files.

Usually however they are placed in the same folder as the utility and not placed in
%windir%\system32 and if so it would have been probably declared differently such as a
hacktool or processkiller, etc.

Yes, beside Virus Total there is the Virus.Org scanner [ http://scanner.virus.org/ ],
Jotti [ http://virusscan.jotti.org/ ] and VirScan [ http://www.virscan.org/ ].

These are the *best* ways to to determine if a given file is malicious with (in my
opinion) Virus Total being the best of the bunch.

This is NOT forensics. This is submitting one file to a service that will have the file
tested amongst a multiture of anti virus scanners.

Using ANUBIS may be considered a forensic examination of a give EXE sample.

Exactly. This is to obfuscate their malicious intent.

The most common name of a legitimate file is SVCHOST.EXE with a myriad of slight
variations.

Good point. I only mentioned that because that might have been a typo on
Steve's part. Googling that message implied a false positive on ZA's
part.

But malware *always* needs to be ruled out. And if Steve has something
called Process.exe, it very well might be malware.

It's present here in sys32 from running an older malware removal tool
for testing purposes, David. Did get an FP on it from a-squared and it
was detected as a trojan, FWIW.
If Steve ever posts back perhaps we'll find out just "what" detected it
as a trojan. <w>
