I have found out what the problem is. I have a trojan called

Trojan.ByteVerify

This is what I found out about it from: http://securityresponse.symantec.com/avcenter/venc/data/trojan.byteverify.html

When Trojan.ByteVerify is executed, it performs the following actions:


Escapes the sandbox restrictions, using Blackbox.class, by doing the following:

Declares a new PermissionDataSet with setFullyTrusted set to TRUE.
Creates a trusted PermissionSet.
Sets permission to PermissionSet by creating its own URLClassLoader class, derived from the VerifierBug.class.


Loads Beyond.class using the URLClassLoader from Blackbox.class.


Gains unrestricted rights on the local machine by invoking the .assertPermission method of the PolicyEngine class in Beyond.class.


Opens the Web page, http://www.clavus.net/lst.backs, and parses the text that this site displays.

For example, SP|www.ewebsearch.net/sp.htm means that the Internet Explorer Start Page will be set up to www.ewebsearch.net/sp.htm


Several pornographic links are added into the favorites.


May attempt to retrieve dialer programs and install them on the infected computer. The dialer programs may attempt to connect the infected computer to pornographic Web sites.


Trojan.ByteVerify will typically arrive as a component of other malicious content. An attacker could use the compiled Java class file to execute other code. The file will likely exist as VerifierBug.Class. For example, an attacker could create a .html file that uses the Trojan, and then create a script file that will perform other actions, such as setting the Internet Explorer Start Page.
Notification of infection does not always indicate that a machine has been infected; it only indicates that a program included the viral class file. This does not mean that it used the malicious functionality.

The only trojan I ever had was, on second thought I won't finish that sentence. Kids are present.
But I did have subseven before, that was fun. And when win2k came out, the server couldn't run on it, but the client could. Meaning I couldn't be infected from it at the time, but I could control it from mine. That was fun.

I changed my name from Phoenix4 to Phoenix5002
Ok. I have found a .dll on my comp that does all the work of this virus that I listed at the top. It is called

mshp.dll

it is located at:

C:WINDOWS

I can't get rid of it. If I delete it it is gone, but as soon as I open internet explorer again the file suddenly comes back. Is there a way to be completely rid of this file, or to somehow detect what keeps putting it back?

you could try deleting it, then set the folder to "read-only". that might stop it at least for a bit.

That doesn't work HZence. It won't allow me to do it to certain files in that folder and

mshp.dll

is one of them

make a system boot disk and delete that DLL. I had someting similar when I caught something called a transponder.
If you want to feel safer about it copy it to the floppy then delete it off your system in case its a required file.

But when I delete the DLL it doesn't come back until I open internet exploerer which is why I think that There is a file somewhere that runs ever time internet explorer does and if the DLL doesn't exist it recreates it. So I think my best bet is to somehow track down what file is makeing that dang DLL every time I delete it.

They always say that prevention is better than cure, so follow these steps to avoid catching nasty viruses:

1. Install a decent anti-virus program, eg: Norton AV
2. Install a firewall - this disables most trojans, or at least alerts you to their presence. Set your firewall to scan in and outgoing email (it will do this by default)
3. Don't use Internet Explorer as a web browser
4. Don't use Outlook as an email client
5. If you have any fairly inexperienced users using the PC, take 5 minutes to teach them about internet security. (In my case this was simple - if a program asks to access the internet, and you don't know what it is, click NO. Don't click the blue E, click the Red dragon instead)

trojans aren't the easiest of the viruses to get rid of. i suggest norton...that seems to help a lot. if a virus does get through the firewalls, i know how to get rid of em'!!!

9 out of the 10 voices in my head say i'm perfectly sane.

Proberly time for a format if you can't get rid of it, then take more care in the future.

Thank you sooo much for all of your help!!
It's been about four days since I contracted this virus and I just couldn't take it anymore so I finally did a format and I am now Virus FREE!!
It was a pain in the rear though but I can finally rest at ease now.
