problems after trojan

on a win98 system, got a trojan, dowload.small.en, after downloading a program from the 'net. AVG diagnosed and killed it but since then this system is acting very weird. It gets annoying popup windows, loses the toolbar, and the desktop icons do nothing after it is on for about an hour. I have to push reset to get it back and then it is fine for another hour or so. :sad:
This kills me because I run spybot and adaware and have spywareblaster installed. Everytime I run one of these now it finds problems and fixes them; I've run them both a few times today and it still happens. I also have the google toolbar and panicware's popup stopper installed. I've run hijack this and bhodmn but they show anything unusual.
Anyone seen anything like this? :rolleyes:

Yes, look in hijack this log for netpal games or variant thereof

Look in the c:\ for an installerupdater.exe
Delete the java applets in the internet cache.

Thanks, NooNoo. I'll try this tomorrow morning.

I looked in the hijack this log but didn't see any entries for either of the items you mentioned. I got curious and installed zonealarm on this system. I noticed that rundll32.exe wanted to access the internet; when I let it I got the popup ads, and if I blocked it the system works fine. It's been running all day without a problem. Does this mean something has corrupted this dll?

Nope, it means you have an adware or spyware DLL on your system. Rundll32 allows a DLL file to run as an executable file, so it's getting blamed for the problem but it's not the real culprit. The DLL that's calling it is to blame.

It will show up in the hijack log, its a question of finding the little bugga...

here is the hijackthis log:

Since i told zonealarm to not allow rundll32 to access the 'net, I get an error message that says "rundll32 has caused an invalid page fault in mrtcp.cpy.dll"
:rolleyes: something strange is running on this system.

go into safe mode, go on a search and destroy mission in both the registry and the system files for the mrtcp.cpy.dll Turn off system restore, otherwise it will be back.

thanks NooNoo. I had to reboot with a floppy to remove that file, in safe mode it said it was in use. One very annoying and stubborn piece of spyware to get rid of.

something else as well.
