Virus error from NOD32 - Win32/Kryptik.JX Trojaner False Positive by NOD32 update from today


Was not a Javascript by browsing the web.



I did search for old eMule mods such as Gamers edition.

My defence system:
Windows Defender with Defination 1.53.92.0 (05. March 2009) - shows nothing (was run in background)
Sysinternals Process Explorer to see hidden prozesses or things that can or do stick on running files in background.
TCP-Z to see under Detail what's connected (in/outgoing) to the computer
some firewall to see on log if realy a trojan is on system which makes connections or fals positive
NOD32 v4 with latest updates


Things I do now running:
http://devbuilds.kaspersky-labs.com/devbuilds/AVPTool/
Kaspersky Virus Removal Tool

can take days 1% in 12 hours scanned

Windows original CD is in drive and have replaced the files to original versions back (possible outdated) - running online update.

I googled for this kind of virus to search but it looks very new, not many solutions to find.
What it does see above, it pack (crypt) up to all windows system exe files also in dllcatch and all backup folders even backup files from vistapack (vistamizer) get infected within seconds.

Read last entry just now found more info (an hour later details to found...)

Nod should better let access to possible infected file to the file properties info to see if signatures/cetrificates are broken and the other file information before erase that user can check the files twice. It haved covert over the system files wrong info in files properties the files did shown as packed (scambled files) lost signature from microsoft, checksum changed, version and file info -> Nod32 was shown like the files are crypted without file infos anymore, all fields by file properties shown empty blank, no one can come on the idea that system files can be false positive infected if they suddenly shown up like crypted files.

correction I found here its error from NOD update:

Nod32 is not bad. Errors can be happen...
