Well, I tried my very best with getting rid of this thing. Now I'm asking for help.
I usually stay very clean with my computer, this is like the 1st time in a very long time I've gotton an infection with a Trojan. Anyhow, maybe I got rid of it. Maybe I didn't. I sort of know what these logs are saying, but then again I want expert advice on whats getting my computer in bad shape. I believe "Trojan.Downloader.Lastad.H" was moved from my windows\system32 folder to quaratine, but I uninstalled the prog that did that, so I dunno what happened to it and forgot the name of the prog. I did my regedit to get rid of what obviously isn't supposed to be on my startup. Anyway, heres my log. I appreciate someone telling me weather I'm safe or not, and if not then point out what looks bad and a lil' advice would help and I can take it from there as I'm no pushover when it comes to dealing with adware, spyware, virus, and trojan.

Anyway, enough babbling. Heres the log:

Welcome to GTG.

You should install at least SP1a for now. Install SP2 after your computer is all cleaned up.

Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should 'not' have any open browsers when you are following the procedures below.

Go to My Computer->Tools/View->Folder Options->View tab and make sure that 'Show hidden files and folders' (or 'Show all files') is enabled. Also make sure that 'Display the contents of system folders' is checked. If you have Windows XP, the search feature is a little different. When you click on 'All files and folders' on the left pane, click on the 'More advanced options' at the bottom. Make sure that 'Search system folders', 'Search hidden files and folders', and 'Search subfolders' are checked.

For the options that you checked/enabled earlier, you may uncheck them after your log is clean. If we ask you to fix a program that you use or want to keep, please post back saying that (we don't know every program that exists, so we may tell you to delete a program that we think is bad to keep).

If you have a fast internet connection (broadband), run an online virus scan at TrendMicro http://uk.trendmicro...call_launch.php. Just follow the instructions on the site to run the online scan. If any viruses/trojans are detected, try to delete or clean them in that site. You may use Panda ActiveScan also at http://www.pandasoft...ucts/activescan. Otherwise, make sure your antivirus program has the latest definitions and run a full system scan.

Reboot into Safe Mode by hitting the F8 key repeatedly until a menu shows up (and choose Safe Mode from the list). In some systems, this may be the F5 key, so try that if F8 doesn't work. Make sure to close any open browsers. Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://hot-searches....h.php?v=6&aff=0
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://hot-searches....x.php?v=6&aff=0
R1 - HKCU\Software\Microsoft\Internet Connection Wizard,ShellNext = http://www.winiso.com/
R3 - URLSearchHook: (no name) - _{CFBFAE00-17A6-11D0-99CB-00C04FD64497} - (no file)
O4 - HKLM\..\Run: [hlc] C:\WINDOWS\System32\hlc.exe
O15 - Trusted Zone: http://www.neededware.com
O16 - DPF: NDWCab - http://www.neededware.com/ndw.cab


Delete the following Files/Folders (delete folders if no filename is specified) according to their directory (if none, just do a search for them) and delete them if they exist:

C:\WINDOWS\System32\hlc.exe

See if you can find these files to delete in the c:\windows\system32\ folder:

kaza.dll
hosts.2
d1k.exe
d1ki.exe
xplugin.dll
tmksrvu.exe
tksrv98.exe


C:\WINNT\nsdb\ - delete this folder

Reboot into Normal Mode run a new HijackThis scan. Save the log file and post it here.
