    Windows ME. Ran Ad-Aware, Stinger, and AVG. Came up with downloader.dyfica.2.p and downloader.dyfica.bp, plus worm zafi.b. Here is the HJT log if someone would help. Thanks.

    Have Hijack This fix all of the following by placing a check in the appropriate boxes and hitting fix checked. Make sure all browser and all Windows Explorer windows are closed before fixing.

    O4 - HKLM\..\Run: [_Hazafibb] C:\WINDOWS\SYSTEM\rydmdhak.exe

    Reboot and delete

    file
    C:\WINDOWS\SYSTEM\rydmdhak.exe

    These may be hidden files. See HERE for how to show hidden files.

    What files are detected as trojans, and what folder are they in? Nothing else is showing in your log.

    Please post a followup Hijack this log, and say if your problems persist.

    Ran HJT and fixed the one dyfica file. Deleted the dyfica file in Safe Mode. Tried to get rid of w32.zafi.b. Stinger sees it but doesn't clean it. Vcleaner doesn't clean it. Tried to go in and delete the files by hand but I can't find them. Attached is new HJT log and latest Stinger log.

    Problem fully resolved. Dyfica gone. Zafi gone. Had to shut off and turn back on System Restore to get rid of Zafi.

    Thanks.
