Hi alexanderp513- welcome to the site :)


Please do the following to start with:

- Download the (free) HijackThis utility from here.

- Once downloaded, follow these instructions to install and run the program:

1. Create a folder outside of any Temp/Temporary folders for HJT and move it there now. A folder such such as C:\HijackThis or C:\Spyware Tools\HijackThis will do.

2. Run HijackThis, but do not have HJT fix anything yet; only have it scan your system! Once the scan is complete, the "Scan" button will turn into an option to "Save log...". Save the log in the folder you created for HiajckThis, open the log in Windows Notepad, and cut-n-paste the entire contents of the log here.

The log contents will tell us a lot about what "nasties" have crept into your system, and once we analyse the log we can tell you what to do from there.

here's the log, thanks

Well, that was fast.

And- Congratulations, you definitely have unwanted guests... :(

Let's start with the following:


1. C:\Program Files\Internet Explorer\iexplore.exe
The log entry above indicates that you had at least 1 instance of Internet Explorer running when you ran HijackThis.
Before fixing problems with HijackThis, you must make sure to close/quit ALL instances of your web browser! HijackThis cannot fully perform its fixes while browsers are running.


2. Open your Add/Remove Programs control panel and uninstall Security iGuard if it is listed there.


3. With all instances of any web browsers closed: scan with HijackThis again, put a check in the boxes to the left of the following entries, and then click the "Fix Checked" button:

O4 - HKLM\..\Run: [Security iGuard] C:\Program Files\Security iGuard\Security iGuard.exe

4. Reboot into safe mode (you get to the safe mode boot option by hitting the F8 key as your computer is starting up)

- Open Windows Explorer, and in the Folder Options->View settings under the Tools menu, select "show hidden files and folders", and uncheck "Hide protected operating system files" and "Hide extentions for known file types".

- Delete the following folder entirely:
C:\Program Files\Security iGuard

- Locate and delete the following files:
smsc.exe
scmsg.exe

- For every user account listed under C:\Documents and Settings, delete the entire contents of these folders (but not the folders themselves):

Important: One of the normal steps in eliminating malicious programs is to entirely delete the contents of all Temp folders. Given that, if any data that you care about is living in those Temp folders, you need to move it to a safe location now, or it will be erased along with everything else!

1. Local Settings\Temp
2. Cookies
3. History
4. Local Settings\Temporary Internet Files\Content.IE5

- Delete the entire content of your C:\Windows\Temp folder.

Note- If you get any messages concerning the deletion of system files such as desktop.ini or index.dat, just choose to delete those files; they'll be automatically regenerated by Windows if needed. Windows will allow you to delete the versions of those files which exist in sub-folders within the main Temp/Temorary folders, but might not let you delete the versions of those files that exist in the main Temp folders themselves; this is normal and OK.

- Empty your Recycle Bin.

- Reboot normally.


5. Run HJT again and post a fresh log.

here is the new log
the only thing is i couldn't find iguard anywhere or the smsc.exe file but i did find the scmg.exe file

That looks like a clean log, although that doesn't necessarilly mean that you're infection-free.

What (if any) of the original problems are you still experiencing?

there are still several Backdoor.Sdbot viruses and W32.Spybot.Worm viruses popping up from norton?
also there were five non cleanable viruses when i did the house-call online virus scan?

Troj small.amt Wmplayer.exe.tmp
Worm rbot.gen Smsc.exe
Worm sdbot.gen Windows.exe
Worm sdbot.gen Winds.exe
Worm sdbot.gen Wis.exe


Lastly, a website i am tring to go to is not loading and is redirecting to msn

Can you tell us where Norton is finding these files? It's possible they are in your System Restore folder.

You can also try this:
http://securityresponse.symantec.com/avcenter/venc/data/backdoor.sdbot.gen.html

As for the redirect, scan with HJT and have it fix:
R3 - Default URLSearchHook is missing

If it still doesn't work, download Hoster from here:
http://www.funkytoad.com/download/hoster.zip

Run it, and when it opens, click on the Restore Original Hosts button and then exit Hoster and try it again.
