I thought I had cleared out the culprits, but apparently not.

I have a pop-up blocker running, and often I'll see an MSIE ad-sized window trying to pop up, but it gets squelched. When I check to see what processes are running, IEXPLORER.EXE is always running (I don't use it as my default browser, but I have it on this system because I occasionally need one bit of its functionality). When I end the process, it goes away, but it always comes back.

What malware will do this? I just removed some junk that was being malicious, but there must be something else I can't find.

iexplorer - iexplorer.exe - Process Information

Process File: iexplorer or iexplorer.exe
Process Name: RapidBlaster parasite

Description:
iexplorer.exe is the executable for a virus that is a variant of the RapidBlaster parasite that downloads and displays advertising from an Internet location. This process should be removed to ensure your personal privacy.

Source: http://www.liutilities.com/products/wintas...rary/iexplorer/


iexplorer.exe RapidBlaster is a task run on Windows startup.
When an internet connection is present it periodically connects to its servers to fetch advertising.
Typically pop-ups for porn sites.
Can download and execute arbitrary unsigned code pointed to by its controlling servers.

RapidBlaster/Rnd is an update which uses pseudo-random filenames.
If it fails to contact its server it will just use 'RapidBlaster\rb32.exe' as with older variants.
If you remove it, it will reinstall itself using a new name.

Installed with ActiveX drive-by download on affiliate pages, including misleading download links (eg. 'megamovieblaster') and pop-ups.
Also can installed by the ISTBar parasite.

Manual removal
Open the Task Manager and end the RapidBlaster process (rb32.exe, or, in the Rnd variant)

Find the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
and delete the 'Something lptt01' entry.
'Something' will be the same as the filename of the RapidBlaster program - you can now delete the folder containing this.

Or remove it from startup by RegRun Startup Optimizer.

If the advice John gives does not work, post a hijackthis log in the hijackthis logs forum and we will take a stab at it.

Thanks. But I don't have an rb32.exe in processes, and don't have one listed in a search of .exe files on the hard drive.

I'll have to go get hijack this and do that.
