backdoor.pclient.B (or is it) and railroad tycoon 3

Since the security update last week, Norton AV 2005 detects the above named
nasty in a temp file called efipsk.sys and deletes it every time I try to
play RT3. But scans in safe and normal mode find no infection. Symantec
analysts can't seem to help, either. Reinstalling the CD allows the basic
game to play without anything being detected, but when the coast to coast
expansion pack is installed (now tried from two different sources), up pops
the NAV alert. Can't find anything in registry as described by Symantec.
Hijack This logs analysed automatically seem clean. Any ideas???

There are anti virus News Groups specifically for this type of discussion.

You called "efipsk.sys" a "temp file". However files with the extension SYS are rarely if
ever temporary files. They are system or hardware drivers.

Is it because it was found such as...
C:\DOCUME~1\<account>\LOCALS~1\Temp\efipsk.sys

If not, where is the file "efipsk.sys" located ?


Please submit a sample of "efipsk.sys" 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, unless told
otherwise, 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.

Hi Dave: You describe exactly where efipsk was found, which is why I mistakenly described it as a temp file. I'll attempt the submission to Virus Total you suggest, though NAV is deleting the file so not quite sure how that will work out. Thanks

VirusTotal is a free service offered by Hispasec Sistemas. There are no
guarantees about the availability and continuity of this service. Although
the detection rate afforded by the use of multiple antivirus engines is far
superior to that offered by just one product, these results DO NOT guarantee
the harmlessness of a file. Currently, there is not any solution that offers
a 100% effectiveness rate for detecting viruses and malware.

Not even Symantec flags this. Make sure you NAV/SAV Signatures oare up-to-date !

It looks like a False Positive declaration.

Hello Dave.

A false positive is my suspicion too, after some investigation. Thanks you
for your help.

Best regards
