avira gave a false positive result??? go figure...
Last night (Wednesday, 02/Apr/08), Avira AntiVir PE Classic (ver7.06.00.270) detected three files in my computer as a possible Virus/Trojan. The warning message basically reads,
"Virus or unwanted program 'TR/Crypt.XPACK.Gen [TR/Crypt.XPACK.Gen]'
detected in file 'C:\Program Files\Tantra Extreme\NGuard.dll.
Action performed: Allow access"
The three files existed in the two minipatches downloaded from Tantra Extreme website.
The three files detected as 'TR/Crypt.XPACK.Gen [TR/Crypt.XPACK.Gen]' are:
* NGuard.dll (197KB)
* NGuard.dll.1 (197KB)
* NGuard.dll.2 (197KB)
At the moment, my best guess is that NGuard is an online game protection/guard file against hacks or cheats.
I did some checks scanning the three files with Avast AV and AVG AV, both AVs found/detected nothing out of the three files above.
I checked Tantra Extreme's website to read the FAQ/troubleshooting/support related with this problem, but found no satisfying answer at all. A Google search somehow led me to a forum where someone posted in year 2004 that there were some AVs that warned of trojan with the game. However, that user said that it wouldn't make sense for the provider of the MMORPG game to release a trojan for potential customers/clients to download and get infected.
Anyway, I ran a search again via Avira's forum site, and the following led me to suspect that I might have experienced a False Positive warning from Avira AV related with the there files above. The links to the forum and other related posts are:
* Spr/psw.ras.a.4.
* XPACK.Gen
* Trojan TR/Crypt.XPACK.Gen : False positive ?
After reading some of the posts at the forum, I decided to follow the suggestion to send to Avira virus lab for analysis.
* Suspicious Files and Miscellaneous Uploads
* Zip the suspicious files with archiving/compression tools like WinZIP, WinRAR, or 7Zip
* Password the compressed files
* Upload the password-protected, compressed files
Within a few minutes later, Avira's website posted the results of the analysis.
File ID/Filename/Size (Byte)/Result
3807732/NGuard.dll.2/197 KB/FALSE POSITIVE
* The file 'NGuard.dll.2' has been determined to be 'FALSE POSITIVE'. In particular this means that this file is not malicious but a false alarm.
File ID/Filename/Size (Byte)/Result
3807733/NGuard.dll.1/197 KB/FALSE POSITIVE
* The file 'NGuard.dll.1' has been determined to be 'FALSE POSITIVE'. In particular this means that this file is not malicious but a false alarm.
File ID/Filename/Size (Byte)/Result

That's real neat! Avira provided such a quick response, and offers user the option to upload, send and report a particular problem. Thumbs up to Avira and crews!
A slight little note... It seemed strange, I remembered compressing three different NGuard.* files, namely NGuard.dll, NGuard.dll.1, NGuard.dll.2. How then did Avira posted a double reply? Unless I didn't managed to properly compress the third file, which is, NGuard.dll.
