Hi everybody

I had two computers infected with ckvo0.exe, ckvo1dll..... :thumbsup:

and also i found that this malware was associated with the autorun.inf file. :trumpet:

I read in another post the solution and it helped me alot.


But it only helped me to clean my Laptop, because it is windows XP with service pack 2

Now i tried the same with my pc
but my Pc system is

Windows XP with service pack 3!!!

I dont know what can I do now! how could I run the combofix software using service pack3!!??

I did the scnas with the Malwarebytes' Anti-Malware software and I also used the FlashDisinfector.

But im not sure if i need to run the combofix software, when i ran it on my laptop i found more malware that the combofix deleted, they were this programs.


My Malwarebytes' Anti-Malware log is:

Malwarebytes' Anti-Malware 1.22

Hello Alexandros.Inc and welcome to BC :thumbsup:

I have moved your post from the HiJack This forum to the Am I Infected forum as it did not contain the DSS log. First some warnings based on what you have written above.

I read in another post the solution and it helped me alot.

Everyone's computer is different with a different arrangement of software. Malware removal instructions, particularly in the HiJack This forum are tailored for a specific person's computer and that specific infection. Someone following those directions on a computer those directions weren't intended for can cause serious problems with that computer.

how could I run the combofix software using service pack3!!??

ComboFix is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert." It is NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Please let us know what other security programs you have installed besides Malwarebytes.

ckvo0.exe, ckvo1dll

How did you determine the presence of these?

and also i found that this malware was associated with the autorun.inf file

How did you discover this?

Hi folks,

I'm interested in this thread too.

A friend of mine got this ckvo0.dll on her computer too. She runs Win XP Pro SP3 with Avast antivirus.

I've googled a lot before deciding to post here. I haven't been able to find conclusive information about how to remove that thing.

I tell Avast to remove the infected file but it reappears on every new boot.

Could anyone give me a tip please?

Alexandros and Todaro,

I am experiencing the same problem. I have windows service pack 3. And, I have installed Spybot with Teatimer (protects registry) and Online Armor for firewall along with Avast for antivirus. Although I have ran Avast in boot-time and one item that was found was deleted, on every other windows start, teatimer does not load. On the other times when everything loads fine, I get an Avast warning message about AVKO0.dll.

Thanks to the registry protection, I don't think AVKO has been able to do much damage on my PC. Still, I cannot remove the darn thing. What do I need to do?

Please advise. Thank you.
