Clients5.google.com is one of Google's subdomans, but might result in strange redirects

Clients5.google.com is a website that users might encounter when they open a new tab on Google Chrome web browsers on Windows or Mac computers. In most of the cases, the suspicious behavior is caused by ATT Mail, Yahoo Toolbar, or other browser extensions that can also be used for Mozilla Firefox, Safari, Internet Explorer, and other browsers.
While Clients5.google.com domain is on itself safe, some browser extensions or applications associated with it might not be. Quite often, potentially unwanted programs[1] that enter machines without user acknowledgment change the search engine, homepage, and new tab functionality. For that reason, users are forced to browse via the hijacked[2] browser and face a variety of sponsored links that initially change the way they browse.
| Name | Clients5.google.com |
| Type | Google's subdomain |
| Related to | Potentially unwanted program/browser hijacker |
| Infiltration | Official sources, third-party sites, bundled software |
| Symptoms | Changed web browser settings, redirects to Clients5.google.com and other sites |
| Termination | To make sure your computer is not infected with a PUP, scan it with FortectIntego. Alternatively, you can remove unwanted programs manually by using our guide below |
| Further actions | Reset Google Chrome |
Besides, PUPs redirecting to Clients5.google.com might also track information about your web browsing activities and serve you targeted ads on all sites that you visit. Without a doubt, if you notice suspicious behavior on your browser, you should remove Clients5.google.com redirects by terminating the potentially unwanted program that might have slipped into your device.
While using the term “Clients5.google.com virus” would not be correct, the suspicious behavior caused by the redirects to the site makes users unsettled, which is understandable, as redirects are a sign of computer infection. As it turns out, the behavior can indeed be associated with a potentially unwanted program.
So-called browser hijackers are applications that change web browser settings in order to show users intrusive ads as well as sponsored links and generate revenue from the behavior. As we previously mentioned, the data tracking activities also help third-parties show the infected users ads that are catering to their linking. The data gathered might include:
- IP address
- ISP
- Geolocation
- Sites visited
- Links clicked
- Bookmarks added
- Cookies, etc.
While data gathered by Clients5.google.com refers to Google, the third-party application that collects such information might share it with its affiliates for more profits.
To sum it up, Clients5.google.com removal should follow up with the reset of Google Chrome browser. Nevertheless, if the PUP infected other browsers, you should also do the same for the others. To make sure all the traces of the unwanted program are gone, scan your computer with FortectIntego.

Learn how to stay away from potentially unwanted programs
Users are often surprised when they start noticing changes to their Google Chrome, Internet Explorer, Mozilla Firefox, or any other installed browsers seemingly out of nowhere. However, potentially unwanted programs like adware or hijackers usually slip in during the installation of freeware or shareware, when users do not pay close attention to the process.
For that reason, users think that the browser changes, redirects, and other unwanted behavior arrived without their permission. In reality, it is not entirely the case. In most of the cases, free applications that are hosted on third-party sites are often bundled together with potentially unwanted programs and are served a single software package.
The infiltration of PUPs happens during the installation of these free apps, as users rarely pay attention to the process. Therefore, you should always make sure that you decline all the offers, check out the ToS and Privacy Policy, and always opt for Advanced or Custom installation mode. In such a way, you will be able to reveal the optional programs that are secretly suggested to you, and you would not be able to see the list by picking Recommended settings.
