    My computer has been infected with "Downloader.Generic. CYH". Neither my
    anti-virus or anti-spyware software can delete or heal this trojan. Please
    suggest how to proceed.

    Hi Starman - You don't say which anti-spyware program you used, so . . .
    Start here, from my Blog, Defending Your Machine, addy in my Signature
    below. It that doesn't fix it, then do the rest of the things I've
    identified there. When you're clean, be sure that you implement the
    preventative measures at the end.


    Show hidden files and run all of the following removal tools from Safe mode
    or a "Clean Boot" when possible, logged on as an Administrator. BEFORE
    running these tools, be sure to clear all Temp files and your Temporary
    Internet Files (TIF) (including offline content.) Reboot and test if the
    malware is fixed after using each tool.

    HOW TO Enable Hidden Files

    Clean Boot - General Win2k/XP procedure, but see below for links for other
    OS's (This for Win2k w/msconfig - you can obtain msconfig for Win2k here: ):

    1. StartRun enter msconfig.

    2. On the General tab, click Selective Startup, and then clear the 'Process
    System.ini File', 'Process Win.ini File', and 'Load Startup Items' check
    boxes. Leave the 'boot.ini' boxes however they are currently set.

    3. In the Services tab, check the "Hide All Microsoft Services" checkbox,
    and then click the "Disable All" button. If you use a third party firewall
    then re-check (enable) it. For example, if you use Zone Alarm, re-check the
    True Vector Internet Monitor service (and you may also want to re-check
    (enable) the zlclient on the Startup tab.) Equivalent services exist for
    other third party firewalls. An alternative to this for XP users is to
    enable at this time the XP native firewall (Internet Connection Firewall -
    ICF). Be sure to turn it back off when you re-enable your non-MS services
    and Startup tab programs and restore your normal msconfig configuration
    after cleaning your machine.

    4. Click OK and then reboot.

    Download and run the free or trial version of A2 Personal, here: UPDATE, then run from a Clean Boot
    or Safe Mode with Show Hidden Files enabled as above

    AVG is ringing a bell as something you don't want to use.... but I might
    be thinking of Anti-Virus Gold (if not the same thing)

    Try using Ad-Aware, and Spybot S&D ( to double check your Anti-Virus,
    provided it hasn't blackholed it, in which case try
