New Trojans pop out every single day, but the old ones do not disappear anywhere, and it makes it even worse when you have a bunch of parasites to watch out for. Trojan.Webprefix has been detected back in April, and it is still troubling multiple users worldwide. To say it more specifically, Trojan.Webprefix steals important information from your computer and then sends it away to remote servers that it is programmed to connect to.

It is hard to pinpoint the exact moment when Trojan.Webprefix enters your system, because this pest can arrive via a drive-by download, or after you click on an infected link on the internet. It might also come bundled with a shareware program, so whenever you download something, make sure of the legitimacy of the program being downloaded. You cannot initially find Trojan.Webprefix in your computer, because upon the installation it copies itself and puts its file in the Windows system folder under a random file name.

It also changes the Windows registry entries and as a result Trojan.Webprefix loads automatically and runs in the background of your system whenever you turn on your computer. When it runs, the Trojan records your computer name, your username and the security identifier name of your account. A further research has revealed that it connects and sends your data to these websites: and It means that with the Trojan in question residing in your computer, you can receive annoying advertisements regarding these websites and the dubious videos that they offer.

Not to mention that Trojan.Webprefix can be the beginning of other hazards for your computer, because Trojans seldom come alone and if you have this pest in your system, it is very possible that others are soon to come barging in. As Trojan.Webprefix does not have a definite interface, look for iview400g_setup.exe process in your Windows Task Manager. This process file is associated with Trojan.Webprefix directly and if it is running in your Task Manager then you have definitely been infected.

You can obviously find manual removal instructions for this pest, but if you are not sure how your system works, or you have never dealt with Windows Registry, it is better to remove Trojan.Webprefix automatically with a reliable computer security program. Do not hesitate when it comes to your computer’s security. Protect your computer and make sure that Trojan.Webprefix is gone for good.
