    That's after a long time after ZMist one of the "best" viruses i've seen.
    It's indeed highly complex - the encryption algo is medium difficult and the virus uses a lot of tricks. I've here some samples with nice antiemulation tricks, such as code performance speed tests (meaning the virus will know when it runs in a virtual environment) and registry dummy - writing tricks, such as trying to write a random value to the registry and trying to read it later and compare it. If not equ or if it doesn't exist the virus exits. The virus is able to act as space filler, same technic was used by the tschernobyl virus already (CIH). The virus is able to use EPO functionallity, it looks for common API calls after the entry point and hooks/redirects them. Means the virus does not execute its own code/decrypter at a fixed position after the entry point.

    Cleaning becomes tricky as Dr. Web already stated correct, however, cleaner will be available soon via my weblog somehow during this week when i have some time.

    Surely faster than the old dos executables and joke programs.

    Does NOD32 detect this virus?

    It doesn't detect the samples I have anyways - I guess they are waiting to figure out how to clean it rather than add 'detection' before this for fear of breaking many infected machines.

    Hi,

    Anyone know of a way to clean this virus it seems a site we have in Athlone, Ireland is infected and has wiped the machines they use. I have just got them to shut down everything untill I can find info on it.

    A full site rebuild is not what I want to advise at this stage.
    Any help would be great.

    If you read at the end of the article from Dr. Web, they can remove it.

    http://info.drweb.com/show/2815/en



    At present, Virus monitoring service of Doctor Web, Ltd. designed the curing procedure for files infected with Win32.Polipos. It was done for users whose anti-virus programs still do not detect this virus and whose computers, though protected by other anti-virus programs, are infected with the virus and let it infect other computers. The curing technique is rather difficult, as it requires processing of a complicated crypt algorithm XTEA, and the decoding of the virus code can take much time. You should not download any additional curing utilities to cure the infected files, just use Dr.Web Anti-virus and update the virus bases on time.

    AFAIK, vendors should have a disinfection routine :thumb: added over the coming days. Dr Web's CureIT! tool can clean it, Mike (Inspector Clouseau) is developing his own disinfection tool also.

    P.S. Greetings from Cork :)

    Hello Cork, if I was closer a pint might have to be bought.

    Do you know what the virus does to the machine after a few days. The users onsite are telling me the machine is wiped, from what I can gather all the documents are gone from mapped drives.

    Thanks for the help.

    if Polipos is as bad as everyone is making out then it would be nice to have at least detection for it even if the cleaning comes later

    Well, Marcos thank you for the answer ...now I know you're not paying attention to these not-dangerous threats like jokes, DOS and phishing e-mails.

    You concentrate on highly-dangerous threats like this p2p worm....which is still not detected by NOD32. :rolleyes: :rolleyes: :(

    Pyko - at least we know the thread is being watched. You should get an answer soon... and maybe detection later :ninja:

    Someone in the 'polipos' thread in the 'other AV' section of the forum claims that Dr Web didn't clean up this virus.
