trojan horse cant be removed

[DavidR]

That was a good find Tech, I have a lot of Doug Knox's Utilities, but that page is very handy to fix multiple file association problems.

As Tech informed you, the exe file association has been broken by a virus:

When you try to launch an application (.exe files), the following error message appears and the program does not run.

Cause

This problem occurs if the .exe file association in the registry is corrupt. This behavior is generally caused by viruses; one of which is SirCam virus, which modifies the .exe file association in registry.

There's also a utility to fix the problem on that page; I'm sure one of the solutions you have been offered will fix the problem quite easily.

As to Trojans, you can scan any suspect files with a-Squared and AVG Anti-Spyware along side avast! as a double check.

Remember Trojans are presented as something you would want on your computer- video codecs, cracks, keygens etc., and also that new Trojans emerge hourly so there's no guarantee any scanner will detect them. The best thing you can do to avoid Trojans is to refrain from pulling large wooden horses mysteriously left outside your doors at night inside you castle: don't download files from dodgy sources.

 Hi "ajoe" :

     I never heard of "Trojan Remover" either; the programs recommended by Frank are those that
    antiSPYWARE Expert Eric Howes recommends at : www.spywarewarrior.com/rogue_anti-spyware.htm#trustworthy . However, one of the ones there that Frank does not suggest is probably
   the best, the FREE version of "SUPERantispyware" at www.superantispyware.com .
    When a security program detects something, should ALWAYS select "quarantine" FIRST, not
    "Delete".
     If none of these programs "solves" your problem, you will most likely need the guidance of
     volunteer EXPERIENCED Malware Experts usually found on antiSPYWARE Support Forums, who
     analyze "logs" from the "HijackThis" program, best downloaded from www.thespykiller.co.uk/files/HJTsetup.exe .
At the download prompt, choose "Save".  
Navigate to the saved file and double-click the installer, HJTsetup.exe.
HijackThis will be installed on your computer at C:\Program Files\HijackThis, making an entry in the start menu and also providing a desktop shortcut.
When the installation is complete, exit HijackThis.

  Since you do not seem to have any antiSPYWARE program on your computer, I recommend
  the forums at www.landzdown.com .

 Frank : Does not "CleanUp" have "Delete Prefetch files" as one of their "automatic" Options !?
           Another thread on this forum recommends NOT deleting Prefetch files" !?

thanks! juz quarantine? not to delete it at all? will it infect other system files in the future?

i sent it to clean up, the technician ... btw, he too installed me another anti-virus, McAfee..

Well this will be avast forum... can you told your technician to get help at McAfee site?
I mean, if he installed McAfee he must have uninstalled avast, so we can`t help with avast anymore.
Maybe you want to come back later
