First things first: UpgradeSearchSystem is a harmless program. It is not a malware that independently harms your system – it’s a simple adware that hangs upon the user and makes him to harm the OS. The working period of any adware might be separated into two phases: the infection process, and the action itself. The infestation phase relies on the user mostly: he wants to find something and, randomly, chooses the infected file. Later, a user installs a program, placing few checks and affirming several pop-up windows in the act of it. In most cases, no one reads the information stated in these windows, but in the malware’s T&C's you can see lots of hidden catches, safely placed in everyone’s sight. UpgradeSearchSystem starts to act instantly after the installation, discovering the user’s preferences and trying to fit them and give away as much pop-ups as it is capable of.

The phase #2 can endure from few hours to multiple days, and the operator of the infected machine supports it too. The ads that begin to appear on the webpages, are useless for fraudsters if the victim doesn’t click on them. To avoid this, hijacker simply displays more and more ads, forcing a user to click. The scheme is simple: if a banner covers the navigation button of the website – customer tries to hide it and accidentally clicks the links. Some victims need many months to become convinced that something goes wrong multiple weeks, but we suppose that you came here to finish it, and now we’ll teach you how to delete UpgradeSearchSystem for good.
