The Zlob.Downloader is a nasty piece of malware that runs on your computer and downloads other harmful spyware, and then installs the spyware without your knowledge. You should remove it immediately - we'll show you how.

You should bookmark or print this page before proceeding.

Zlob Downloader has been most frequently associated with the SmitFraud family of spyware infections. However, you may have Zlob without having SmitFraud, so it is important to run through ALL the steps in this tutorial.


Step 1: Run SmitfraudFix

The first step is to download SmitfraudFix here. It's a ZIP file, so once it has downloaded, you will need to extract (unzip) it. (Click here if you're not sure how to unzip files).

The SmitfraudFix download site also offers instructions on how to use SmitfraudFix. Follow the instructions exactly.

Note: If you plan on getting help from our spyware removal experts in the Spyware Help Forum, do the following: After selecting Option 1 (Search) in SmitfraudFix and before selecting Option 2 (Clean), rename the rapport.txt file in your C:\ drive to report1.txt. That way, if the spyware fighters in our Spyware Help Forum ask you for those files for analysis, you will have them.

SmitfraudFix does an excellent job of removing most SmitFraud infections, however there is still more work to be done. Once it has finished, return to this tutorial and go through the next two steps.


Step 2: Run SuperAntiSpyware 

The free SUPERAntiSpyware scanner effectively removes the Zlob.Downloader trojan - follow the steps in our SUPERAntiSpyware tutorial to download and run this tool.

When it is complete, reboot your computer again.


Step 3: Run Online Virus Scanners 

Now run the Panda ActiveScan virus scanner and the Housecall virus scanner as detailed in Step 1 of our guide to Get Rid of Spyware, Adware, and Web Browser Hijackers. Only then can you be completely sure than your computer is clean from infection.


You should now be free of Zlob Downloader - however, you may have additional spyware on your PC. These things tend to travel in packs ;) Go through the rest of the instructions in the Get Rid of Spyware guide to remove any other infections, and to protect your PC from future spyware.

If you have been referred to this Tutorial from the help forums:  please find the C:\rapport.txt file. Open it in notepad and copy & paste the contents in your next post in the forum.
