Nava Shield or NavaShield is a rogue anti-spyware which is known to be using forbidden methods of distribution.

That means that this scamware relies on Trojans that sneak inside the system undetected and additionally download NavaShield. Such viruses may stay on your computer undetected because legitimate security programs are disabled since the intrusion. Of course, you may be tricked into installing Nava Shield manually, because on its misleading pop-ups it continuously offers installing free trial version for a week.
Nava Shield infiltration is followed by these signs common for any other rogue anti-spyware: system tray alerts, security scanners, fake Windows Security Center pop ups and notifications that report about dangerous virus detected. It may even start playing scary sounds on your PC! Those misleading alerts and scanners imitate scanning computer’s system and after finding “dangerous threats” offer to purchase NavaShield commercial software for a removal. In fact, it is very important to keep in mind that so called “registered” version of Nava Shield is useless and even dangerous just like the trial its version. This scam has no spywares’ detection or removal engine, so it won’t save your computer and rescue its system. Contrary, it may ruin it because NavaShield is known to modify settings of the infiltrated computer and also disrupt Internet connection. Besides, if you don’t pay for it and simply leave it on your computer, you start hearing continuous sounds, like laughing or others.
So, don’t believe any alert displayed by this rogue anti-spyware because it reports only invented threats. Keep this information in mind and remove Nava Shield. 
Kill malicious Processes from Task Manager:

  • NavaShield.exe 
  • NavaUpdater.exe
  • NavaBridge.exe
  • NavaDebugger.exe 
Location of the infection:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings “ProxyOverride” = “”
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings “ProxyServer” = “http=
Although it is possible to manually remove NavaShield, such activity can permanently damage your system if any mistakes are made in the process, as advanced spyware parasites are able to automatically repair themselves if not completely removed. Thus, manual spyware removal is recommended for experienced users only, such as IT specialists or highly qualified system administrators. For other users, we recommend  malware and spyware removal applications.

After removing all these files, restart your computer and the issue will be fixed. And don’t forget to do update your Security Software, check the Firewall Settings and the Operating System and finally do a full system scan with the Security Software.
