It is extremely surprising that the Spyware.Navihelper application has been active since 2005, which means that the malicious virus is getting close to successfully infecting Windows systems for whole ten years. This clandestine program is capable of implementing browser helper objects into your system and collecting private browsing information. This type of data later on could be used to serve schemers as a base for personalized, misleading online advertisement attacks; however, if you do not detect and remove Spyware.Navihelper, this latent cyber criminals’ tool could bring even more danger to the security of your personal data and, ultimately, personal security.

There are plenty of devious ways for the treacherous Spyware.Navihelper to get into your computer and it is very possible that the infection gets installed as you hit Agree button on some sort of virtual Privacy or User License Agreement forms. It is not so uncommon for schemers to inform users that the products you download could be affiliated with applications recording your browsing/surfing activity, only because it would be hard to find those Windows users who actually read through the lengthy and complicated rules of some kind of software usage. Nonetheless, this is not the only propagation channel that could be applied, and you should also beware of bundled downloads, misleading advertisements or supposedly legitimate and safe browser add-ons.

Despite that the malicious program has multiple alias names (e.g. Adware/ADnavi, Adware-NaviHelper, Spyware:Win32/Navihelper), its core elements are capable of the same malicious actions and processes. NaviHelper.dll, or 98160572.dll, can be located under C:\Windows\System32\NaviHelper.dll, and this component can initiate spam email attacks using your accounts, create unauthorized FTP connections or make sure that Spyware.Navihelper does not get detected and removed. This is the aforementioned browser helper object file, so NaviHelper.dll can also steal login data and other personal information. Setup.exe is another danger to your system’s security, as it can delete processes, modify Windows Host File feature, remove or add Start Menu items, possibly creating difficulties with system’s management, reconfigure Windows Security System, disable safe mode, or even remove access to Task Manager and Registry Editor, all of which regularly could help identify and delete Spyware.Navihelper

Manual Spyware.Navihelper removal is a task performed at infected system’s user’s own risk, and we will not take any responsibility if any significant system integrity issues come up. This is because this operation is truly tricky and may fail even using extensive removal instructions. If you do not think your removal skills and expertise are strong enough, it would be best to employ automatic tools to have Spyware.Navihelper deleted.
