    How does "mytob" virus work?

    I have a friend who is having problems with constant emails from "supportteam@theiraddress.com" and such aliases!!!

    Reading forums and such, it sounds as though the "mytob.ee" worm seems to execute these sort of emails... and Norton picks these files up in scan when the emails are downloaded...so i ran a Hijackthis scan and nothing out of the ordinary appeared.

    I then downloaded a fixmytob tool off Symantec... this did not find anything!!!

    Would anyone be able to suggest where to look to stop these emails coming through... numbers are getting to about 50 a day... and its quiet worrying if it is a worm causing all this aggro lol!!!

    Many Thanks

    Why don't you do this please:


    Download the new version of hijackthis here:

    http://majorgeeks.com/download3155.html

    Please Create a folder HJT such as C:\HJT. Download HijackThis program to the newly created folder. Then make or alter the shortcut to the HJT program.

    Notepad will open up and results of scan will be there, copy and paste that into your next reply. Thanks.

    That file you mentioned is legitamate


    WinTasks Process Library
    lsass - lsass.exe - Process Information

    Process File: lsass or lsass.exe
    Process Name: Local Security Authority Service

    Description:
    lsass.exe is a system process of the Microsoft Windows security mechanisms. It specifically deals with local security and login policies.

    There isn't anything showing in the HJT log so let's do some scans and see if anything shows up.


    Get the stinger here:
    http://vil.nai.com/vil/stinger/

    Download it to another computer if need be, and bring it to the affected computer on floppy disk.

    It will kill the top 53 virus files if any are found there

    then,

    Internet Explorer required
    Run these two online virus scanners (Panda Activescan) following these instructions below:
    http://www.pandasoftware.com/product..._principal.htm


    Internet Explorer required
    Also this excellent(BitDefender) scanner:http://www.bitdefender.com/scan8/ie.html

    These scans can and will take over an hour to complete but both scanners Panda and BitDefender both will make logs of what they find please save those and post them back here with a new HJT log as well. Thanks

    Save 20% on AVG Internet Security 2012 Suite!
    Not sure try this and see if the file for that worm is there, maybe not what is happening.

    That worm usually shows up as an 04 entry in Hijackthis


    Make sure you can see hidden files/folders
    In Windows XP
    Click Start.
    Open My Computer.
    Select the Tools menu and click Folder Options.
    Select the View Tab.
    Under the Hidden files and folders heading select Show hidden files and folders.
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.
    Click OK.
    After you're cleaned, please "rehide" them again.


    Try this online scanner also:

    TrendMicro


    If you do have the worm it will be in the system32 folder


    Go here and look at all the known files that is this worm, look for and delete, good luck.

    http://research.sunbelt-software.com...threatid=39854


    If any are found you will need to delete from safe mode.


    reboot into safe mode by tapping your F8 key upon restart and safe mode screen appears, select safe mode and press enter.
