Zlob.Downloader.XOT is a Trojan harmful Adware, which is usually installed in your pc windows (Windows 2000, Windows XP or Windows Vista) via an outdated Java Runtime Environment. In the letter C: windowssystem32 and Vundo, also known as Zlob.Downloader.xot Virtumondo creates random DLL (tyeyavv.dll for example) themselves to inject into the process of winlogon.exe and explorer.exe process. Since Vundo itself injects winlogon.exe removal can be very difficult, because winlogon.exe is used almost every second. The biggest problem with Vundo is not necessarily the deletion process, but it is actually the detection process since Vundo creators are hundreds of variants per day in order to escape detection (which seems to work unfortunately).
What are the symptoms of a Vundo Infection?
Vundo unbreakable displays popup and popunder ads even when users are not actively internet navigation. Vundo is also known to display fake system alerts that pushing a user to buy an anti-virus application false. Vundo is essentially a platform to deliver scams to your PC to large-scale non-stop.
How to remove Vundo with free software - My Vundo Removal Kit.
Remove Vundo free can be a little difficult, since there are so many variants of Vundo and every free program is a different detection algorithm of database and heuretics.
When I meet Vundo and a client does not want to pay for any software I "out" my free Vundo removal Kit. This kit is currently composed of:
-MalwareBytes antimalware (malwarebytes.org)
-SuperAntiSpware (superantispyware.com)
-VundoFix (of atribune.org)
-Rundll (from eset.com)

28 Do yourself a favor and buy the Spyware Doctor with Antivirus (license protects 3 PCs). It is the only antivirus that I've tested this year to correctly detect and remove almost every variant of Vundo with very little effort.
If you think that any Vundo Trojan horses have been missed in c: windows or c: windowssystem32 and then you scan submit these files to VirusTotal.com for analysis. If the file that you submit returned as an infection as possible then you can remove by force using Rundll. If you still get popup ads then you can run a HiJackThis scan and send me the log file, or simply install Spyware Doctor with AntiVirus.
