I am a victim of browser hijacking. Today I was browsing the web when several annoying pop's were displayed. A specific one (porn) draw my attention not because of porn but because everytime i delete the cookie, url on the temp folder it kept coming back.

So this prompt to do additional search on my computer and I found an ugly Spyware name XUPITER. XUPITER consists of an internet explorer toolbar containing link buttons to one of Xupiter's search engines and a task run at Windows startup which downloads updates to the software and may launch pop-ups.

It also contain functionality to hijack your home page and search settings, and add Xupiter links to your bookmarks.

Then went to look for the folder and founf XUPITER folder under Program Files. Try to delete but it did not allow me to do it. Then decided to look further on the registry and this is what I did to remove this ugly thing:

Start Regedit

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Delete the DWORD "XupiterStartup"
Run the following commands to unregister the various DLLs - note that some of the files may not exist on your computer.
cd c:\windows\system (or as appropriate for your computer)
regsvr32 /u "C:\Program Files\Xupiter\Updates\XupiterToolbar.dll" Repeat for xtupdate.dll, xtsearch.dll
regsvr32 /u "C:\Program Files\Browser\Updates\BrowserToolbar.dll"
Repeat for xtupdate.dll, xtsearch.dll
regsvr32 /u "C:\Program Files\Browser\Updates\BrowserToolbar.dll"
Repeat for bwupdate.dll and bwsearch.dll cexx.org reports that the following DLLs may need to be unregistered as follows:
regsvr32 /u "C:\Program Files\Sqwire\t.dll Repeat for u.dll and s.dll

Now my question:

What type of spyware is XUPITER? A worm? Trojan horse?

Can anyone give me links to site to prevent computer or browser hijackings?

Thanks for you help
