ChatZum is a Potentially Unwanted Program that installs a Toolbar into your browser. This program allegedly allows users to zoom in on photos without clicking on them, however, upon further research, it was discovered that this function does not work on the latest version of browsers.
From the Author: ChatZum is a Browser add-on (toolbar) that enables its users to hover over images in Major Social network's websites and view a larger version of an image.
While installing this toolbar will track user web browsing sessions and will record website visits, clicks, and sometimes even personal information. This information is later used to display targeted ads to the user. To allow easier user tracking, the program changes the browser home page and default search engine to Nation Search Advanced, which injects additional advertisements and tracks user activity.
Several anti-virus applications have marked this program as Potentially Unwanted, and it is not recommended to keep it on your computer, especially considering the fact it will most likely not work on your browser.
If you have ever installed a free application or shareware, chances are high that the computer will get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has got other hidden objectives. These types of programs are generally bundled up with a free application that you download from the internet or may also be bundled inside the custom installers of many download websites.
PUPs aren’t always viewed as “pure” malware in the strictest sense. A fundamental difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who knowingly or unknowingly approves the PUP installation on their computer system. But, there is no doubt that PUPs remain bad news for PC users as it could be quite dangerous to your computer in many ways.
The unwanted programs after installation display numerous annoying pop-up ads, trigger fake alerts, and sometimes even forces a computer owner to pay for the software. PUPs that come as browser add-ons and toolbars are commonly recognizable. These toolbars alter your homepage and your search engine in the installed web browser, track your web activities, modify your search results with redirects and sponsored links, and eventually slow down your browser and diminish your browsing experience.
Potentially unwanted programs use aggressive distribution methods to get onto your computer. The worst part of setting up a PUP is the adware, spyware, and keystroke loggers that could lurk inside. Even if the PUPs really aren’t inherently malicious, these applications still do practically nothing good on your PC – they’ll take valuable system resources, slow down your PC, weaken your computer security, making your PC more vulnerable to malware.
• Read the EULA thoroughly. Look for clauses that state that you have to accept advertising and pop-ups or bundled applications from the company.
• Always opt for the custom if you’re offered an option between “Custom” and “Recommended” Installations – never ever click Next, Next, Next thoughtlessly.
• Use a good anti-malware application. Try Safebytes Anti-malware which can find PUPs and treat them as malware by flagging them for deletion.
• Be alert if you download and install freeware, open-source applications, or shareware. Do not ever install software applications that seem shady or malicious.
• Always download applications from the original website. The majority of PUPs find their way onto your laptop or computer is via download portals, so steer clear of it altogether.
Remember the fact that even though PUPs could potentially cause damage and hinder the proper functioning of the PC, they can’t enter into your system without your consent, so be alert not to provide them with it.
