    I have ran numerous trojan software that pinpoint this infected file...C:\Windows\Tmp\SF9043.TMP\cupdate.exe It is a Trojan downloader.kb---but all programs have failed to remove it. I have searched every where for info on this and have come up empty.

    Would it be safe to just delete the TMP file and make a new one?

    When I go into the Tmp file I do not see this file so it must be hidden. When I use the Find it does not find it. So why do the various online scans and other trojan software locate it but are unable to remove it? I am not that experienced with computers so I am not even certain if I should delete it once I have access to it. Is this something that DelLater could handle?

    I did install Regprot and denied it access to the registery.

    I'd be forever grateful for any help!

    just empty the complete temp folder

    Reboot into safe mode by following instructions here: http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406
    then as some of the files or folders you need to delete may be hidden do this:
    Open Windows Explorer & Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked. Also uncheck "Hide protected operating system files" and untick "hide extensions for known file types" . Now click "Apply to all folders"
    Click "Apply" then "OK"

    then go to C:\Documents and Settings\USER NAME\Local Settings\Temp and select everything in that folder and delete it (repeat for every user name/account )

    and select EVERYTHING in C:\windows\temp except temporary internet files, cookies and history folders and delete all that as well and everything in C:\temp

    Thank you so much Derek for your help! My system is now clean again which was important because this is a brand new computer and I did not have a chance to make a back up file or boot up file before becoming infected.

    Anti-Trogan and Swatit had failed to catch the trogan but BitDefender, Panda and StopSign all detected it only Panda was able to remove it.

    I noticed you mentioned to use CSW that you had to update Visual Basic Runtime Libraries. If I do that is there a chance that some of my other software won't function properly then? And where exactly do you place them once the file is unzipped?

    I would like to know what is the best virus protection and firewall that I can apply that will function together without problems?

    I am running WIN98 SE and have problems with it hanging up on closing. I went to the Mirosoft help section and followed their advice and it totally screwed up my computer, so much so that I had to run the backup. Is there so way to fix this issue?

    I do plan to run Hijack so I will have a copy of what my system looks like clean of any viruses or spyware. How do I make a copy for future use?
    Is there another way to make a copy of the registry?

    Best of luck with your hedgehogs...I do similar rescue effects with abuse horses from auctions.

    Thanks again Derek for your time!

    Dee :D

    TDS should have remobved it completely

    Did you install TDS

    TDS3 from http://tds.diamondcs.com.au/

    download & install the 30 day free trial, update it manually as described here http://tds.diamondcs.com.au/index.php?page=update as the trial version doesn't have auto update enabled

    then press scan control & tick all the little boxes in the bottom part of that window, press save configuration and then close that window by pressing the red X in top right corner, then select system testing and select full system scan

    sit back with a cup of coffee and watch what it finds

    NOTE:

    Unlike set and forget av's TDS works with you, it doesn't auto delete anything but puts a list of found suspect files in the bottom window

    right click any file it finds and it gives you options on dealing with it, the normal selection would be delete , but first select "save as text", that will create a logfile of all the found suspect files and put it in the TDS directory called scandump.txt.

    post back with the tds log after running please, just copy & paste the entries from the scandump.txt


    Many programs use the VB runtime files so it is well worth having them just click on this link and it will download, then double click the .exe file and it will automatically install to the right place

    http://download.microsoft.com/download/vb60pro/install/6/Win98Me/EN-US/VBRun60.exe

    any program that is using the OLDER version will still work with the new version

    Thanks Derek for the comprehensive replies :)

    In addition to Dereks suggestions I would also suggest installing WormGuard as it has great script & worm catching abilities.

    Purchasing TDS3 or WG3 entitles you to a free upgrade to the forthcoming TDS4 and WG4. Might Ialso suggest that you try Port Explorer which allows you to see exactly what is going on with your external connections.
    You could also consider buying them together as extra discounts are available www.diamondcs.com.au/index.php?page=shop
