CB Ad Rotator ads. How to remove? (Uninstall guide)

removal by Olivia Morelli - - | Type: Adware

What system changes are initiated by CB Ad Rotator virus?

CB Ad Rotator virus is not a typical adware-type program. Once it enters its target PC system, it alters proxy settings so that it could redirect its victim to Privoxy server. This server is also launched on the target computer as an oxy.exe file, so if you can see this executable running, you might be infected. In addition, you should see CB Ad Rotator ads injected into your favorite websites. In most of occasions, they show up in a form of sponsored pop-up ads and banner ads. Its ads can be extremely annoying because their aim is to collect a considerable amount of money from advertising. In truth, this software uses questionable ways to provide this service and you should not trust its developers. If you noticed ads caused by this potentially unwanted program, there is no denying that it is already running on your computer. In such a case, you should run a Reimage scanner, or some other antivirus utility you trust, and remove CB Ad Rotator from your computer without wasting much time.

An illustration of CB Ad Rotator ads

This virus specifically belongs to the category of adware which uses the Privoxy server to display their ads. So, as soon CB Ad Rotator gets on the victim’s computer it changes the browser’s proxy settings and starts directing your traffic through this particular server. You can find this process running on your computer as oxy.exe. This redirect allows the virus to generate ads on your visited websites and even track your online activity and web traffic. Typically, the advertised content will vary. The injected pop-ups, banners, and other ads may lead to gambling sites, involve you in tech support scams or urge you to download suspicious software, but they may promote legitimate products as well. There is no way of knowing which ads may be infectious. Thus, you should not risk getting scammed or having your device contaminated with malware and proceed to the CB Ad Rotator removal recommendations discussed below. However, in case you are interested how adware spreads and how to prevent its hijack, please keep reading further.

How can I protect myself from hijack?

CB Ad Rotator is a typical example of an adware program since it spreads through software bundles and is installed without a direct user’s consent. The permissions, though, should still be granted. Otherwise, the program will not be able to install. Luckily for the malware creators, the users rarely read through the EULA and other related data, meaning that they do not really pay attention to what they agree to install. A majority of the virus victims agree to have rushed through the software installation using the default “Quick” or “Recommended” settings before they found CB Ad Rotator on their computers. Unfortunately, these settings do not disclose the full list of the software package contents and install them automatically. “Advanced” or “Custom” modes, on the other hand, allow making changes to this list and canceling undesirable content.
