We have recently had a home PC infected (with SMART H.D.D and maybe more). After many, many anti-malware scans with various anti-malware products, registery fixes, etc., we have finally gotten the PC "cleaned" enough to boot into normal mode and appears to be stable so far.

Finally, last night, we uninstalled McAfee and installed our newly purchased Kaspersky Pure 2.0 and ran a Full Scan. The Full Scan found the following threats:

Trojan-Spy.Win32.Carberp.e (from Outlook email ... UPS_Print_label.exe) ... Reason is: Disinfection impossible

Worm.Win32.Mabezat.h (from Outlook email multiple attachments - ...e_231.zip // Gift_Certificate_231.exe // UPX) Reason is: Disinfection impossible

Trojan-Dropper.Win32.Agent.bzst (from Outlook email attachments ... iTunes_certificate_297.zip // iTunes_certificate_297.exe //UPX Reason is: Disinfection impossible

My questions are:

1. What does the Fix button actually try to do?

2. Can we even "Fix" them since Kaspersky gave reason of: Disinfection impossible (is this because they are "packed" or "zipped"?

3. What are these Trojans and the Worm we found and what is the behavior and threat description for these?

4. What is a UPX?

Thanks for your help.

**In any case where you happen to be busy or unable to give us a reply, we would be grateful if you keep us informed in advance and we will be more than happy to wait. Failure to do so we will have your thread closed in THREE(3) days. :)

Hello there, nv87654


I'm Conspire, I'll be glad to help you with your computer problems.

Please observe these rules while we work:
  • Read the entire procedure
  • It is important to perform ALL actions in sequence.
  • If you don't know, stop and ask! Don't keep going on.
  • Please reply to this thread. Do not start a new topic.
  • Stick with me till you're given the all clear.
  • Remember, absence of symptoms does not mean the infection is all gone.
  • Don't attempt to clean your computer with any tools other than the ones I ask you to use during the cleanup process.

IMPORTANT NOTE : Please do not delete anything unless instructed to. Remember to backup all your important data(if possible) before moving on.


1. Not sure what Fix button you are referring to.

2. Based on my first observation, I can tell that these detected items are mainly from your email attachments. You will need to delete them manually but careful not to open attachments inside.

3. The behaviour of these trojans and worms generally will spread itself once executed. It will drop some files and patch system drivers to allow hackers access computer through backdoor. Kind of like someone jumps into your house and open your backyard door to let other burglars in.

4. UPX is a packer for executables. It's more of a file compression program to reduce the size.
