View Full Version : TDS 3.21 - FALSE trojan identification

TDS 3.21 (full, regged) reports and prevents

desertcombat_0.5l_beta_full_install.exe

from excecuting with Excecution protection installed.

I've downloaded this file from four different sources and all of those TDS has labelled with:

Alarm: Positive identification
Name: <empty>
File: desertcombat_0.5l_beta_full_install.exe

AFAIK, this file does not contain a Trojan.

At least nothing on my system scans positive after I've installed Desert Combat, removed the installer and done a full scan (NOD + TDS + A2 + some online scanners).

regards,
Halcyon

Hi Halcyon, Would you be kind enough to zip & send the file to submit@diamondCS.com.au Or if the file is very large supply DCS with the download link that you used & the file data of your DL'd copy so that it can be analysed.

Thank you. Pilli

Hi,

Looks like a false alarm, or there would be a trojan NAME listed. Very interested to see the file if you send it. After which I would suggest update the database again and scan that file

I forgot to tell you that the file is 541 megaBYTES, so I'm not going to be sending it anytime soon :)

It's a freely available modification to a well known game called Battlefield 1942 and available for instance in the following locations:

Many installers use the same methods as trojans to install, so TDS might be picking up on one of those "install methods" and flagging it

Hmm.. very interesting. I had a feeling it was going to be a big file :)

There is a database update in 15 minutes, please scan with the next database. It may have been corrupt, otherwise this could be a bug related to TDS scanning such a large file

If youy are referring to the above file being corrupted, no that was not the case.

I downloaded it from four different locations and all of them triggered the same alarm in TDS-3.

However, all of them install / pass CRC fine after I remove TDS-3 execution protection.

After installation put exec protection back and scan the whole folder and other parts of it, maybe better a whole deep canning full system scan, just to be very sure.
Enjoy your game!

Yes, that's just what I did :)

No ALARM after installation of the mentioned Desert Combat file for files that have been installed (or any other files, except the installer).

I updated the database and did a new scan on the installer. It doesn't report an alarm anymore.

Thanks!
