    Hello all... here's a sure FP...
    I downloaded the Executable as well as performed an built in update and both detected and killed by NOD32 3.0

    A scan at virus total came up clean:
    [ file data ]
    * name: PREVXCSIFREE.EXE
    * size: 621624
    * md5.: 5b3f4f9e32eafe0a975bafc596baed9d
    * sha1: 48a2770a41849ed7a9a42d0c3d00ef8ed89d293d

    Sorry, I already had it posted in the "other malware Thread"....

    I did send an e-mail about the FP to ESET support on monday.

    The download is clean on virustotal, it's prevxcsi.exe in a temp directory that triggers the heuristics.
    Or the same file if the program is installed.

    "probably a variant of Win32/Genetik trojan"

    Also detected by another AV as Generic9.AYPR and some suspicious AV's think it's Suspicious :cool:

    Strangely enough I don't get the FP with NOD2.7.o_O

    Did you install the latest release (v1.2.103.196 or higher)?
    And are NOD32's heuristics enabled?

    The answer to both questions is Yes.
    On another machine AVG Free also 'detects' it as a threat (Trojan horse Generic9.AXPJ).

    I guess version 2.7 is using another heuristics module.

    Did try to run the file on another machine with NOD32 v 3 def. 2852 and it got busted again.
