Can't Close Google Chrome Virus (Mac)

Also Known As: "Can't Close Google Chrome" system error
Type: Mac Virus
Damage level: Medium

What is Can't close Google Chrome?

If the Google Chrome window (browser) keeps reopening after closing, it might be caused by an adware-type application present on your computer.

One adware-type app known to cause this issue is MacSecurityPlus. Like most potentially unwanted apps (PUAs) of this type, it delivers intrusive advertisements and gathers information relating to users' browsing habits. Note that most people download and install adware-type apps unintentionally.

Can't close Google Chrome adware

MacSecurityPlus prevents Mac users from closing Google Chrome and, as with virtually all adware, also feeds them with various pop-up ads, coupons, banners, surveys, and other unwanted items. This conceals underlying content of visited websites. If clicked, these ads might open dubious websites.

In some cases, clicking dubious ads might cause download and installation of unwanted software that could be malicious. Furthermore, PUAs often operate as information tracking tools. They gather data such as IP addresses, geolocations, URLs of visited websites, entered search queries and other data relating to users' browsing habits.

Furthermore, people who develop these apps usually share the data with other parties (potentially, cyber criminals) who misuse it to generate revenue. To avoid problems with privacy, browsing safety or even identity theft, we recommend that you uninstall MacSecurityPlus and all other installed unwanted apps.

Adware-type apps are often downloaded and installed intentionally, since developers promote them as useful apps. Unfortunately, once installed, they start to cause a number of problems. They deliver no real value and are designed only to generate revenue for the developers and other third parties.

There are other cases in which it is impossible to close the browser due to adware-type apps installed on the system. There is more information in this article.

How did Can't close Google Chrome install on my computer?

Some PUAs can be downloaded from their websites, however, in most cases, people cause these downloads and installations unintentionally when they click intrusive ads (which execute scripts designed to cause unwanted downloads/installations) or when developers use a deceptive marketing method called "bundling".

They include unwanted apps with other software set-ups. Developers usually hide PUAs in "Custom", "Advanced", "Manual" and other similar options/settings of the download, installation set-ups. Furthermore, in many cases, people cause installation and download of unwanted apps simply by skipping setup steps and leaving available settings unchanged.

How to avoid installation of potentially unwanted applications?

Handle each software download and installation process properly. Check all available settings and options (such as "Custom", "Advanced") and opt-out of additionally-included (bundled) apps. Do not download software using third party software downloaders, torrent clients, eMule (or other P2P networks), dubious websites, and so on.

Do not click various ads, especially if they are displayed on dubious web pages such as gambling, pornography, adult dating, and so on. If clicked, they redirect users to untrustworthy websites or cause unwanted downloads and installations. If these redirects occur even without clicking ads, or unwanted ads appear on all pages, it is likely that installed PUAs are the cause.

Check installed extensions and add-ons on your browser and remove any suspicious entries. Also check the list of installed programs on the operating system. If your computer is already infected with Can't close Google Chrome, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
