Remove Googlesyndication (Removal Instructions)

Googlesyndication is a suspicious ad that asks Mac users to download unknown files

Googlesyndication

Googlesyndication is a popup that users might encounter at any time on Safari, Google Chrome, or Mozilla Firefox web browsers. Upon entering a random website, Mac users said they started receiving a message that asked them to download a suspicious file from “safeframe.googlesyndication.com,” “tpc.googlesyndication.com,”^[1] or another URL. In other cases, users' browsers were redirecting via these addresses to unknown websites.

Due to this suspicious behavior, people labeled Googlesyndication as a virus. However, this activity is not likely to be related to adware or malware infection, but rather an internal issue with the Adsense advertisement network. Similarly to Ad.doubleclick.net, it is a legitimate part of the ad delivery service hosted by Google. However, it is not the first time the company stumbled, and the Googlesyndication popup is related to a rogue ad that managed to bypass implemented security defenses. Luckily, this issue can be fixed easily by accessing your web browser settings until better solutions can be provided by Google.

Name	Googlesyndication
Type	Ad delivery network
OS	macOS, Mac OS X
Issue	Users are getting popups that asks them to download files such as “container.html”
Reason	Rogue ad that bypassed Google's scanners
Related	F.txt.js
Removal	Blocking the automatic download feature from unknown sites can temporarily stop unwanted download prompts. In case your web browser is displaying other suspicious behavior (redirects and intrusive ads) you should scan your machine with security software, such as SpyHunter Combo Cleaner

Initially, it is impossible to remove Googlesyndication, even if it is serving you ads. There are millions of websites that use Google's Adsense to monetize visitors' visits by showing ads. In other words, the ads are coming directly from the website you are visiting, and these can sometimes be stopped with third-party tools, such as ad-blockers.

So, many might wonder what might have happened? The truth is, while Googlesyndication is a part of a broad advertising network, the prompts that users are getting should never be trusted regardless, as they might be related to malicious activity (you might infect your Mac with malware). Thus, if you encounter such popups asking you to download suspicious files, never agree to it, and close them down immediately.

The biggest problem that users have is that they ran out of options on how to remove Googlesyndication popups, as they can be particularly annoying. Since these prompts are shown via Google's advertising network, there is no easy task to tackle this problem, as the company needs to deal with the rogue ad that managed to slip through.

As a temporary solution, Googlesyndication removal can be performed by accessing web browser settings and blocking particular websites trying to make you download files. The problem should be fixed by Google later automatically, however.

On the other hand, if you are experiencing some or all of the following symptoms, there is a possibility that it has nothing to do with the Googlesyndication situation itself:

Changed homepage and new tab address;
Alternative search provider set on the homepage;
Redirects to suspicious or ad-filled websites;
Unknown extensions installed on the web browser;
Unknown apps installed on a Mac;
Search hijacking issues, etc.

In such a case, you should look for adware or other malicious software on your Mac. Adware is especially prevalent on this operating system.^[2] You can either scan the device with anti-virus software (SpyHunter Combo Cleaner, Malwarebytes Malwarebytes, or other reputable security tools), or look for unwanted programs manually – we provide the instructions below. As an optional step, you could also check your system with Fortect Intego for the best results.

Googlesyndication popup

Safeframe Googlesyndication

Safeframe.googlesyndication.com is an URL address that appears on a popup message when users access random websites. While such behavior can commonly be connected to malicious JavaScrips on malware-laden sites, this pop-up can show up on legitimate websites, such as Wikipedia. By all means, these sites are not serving you malware; it is again malicious ad's fault.

Safeframe.googlesyndication.com can serve all types of files to be download, although many users claimed that the URL simply asks for permission to download files:^[3]

Do you want to allow downloads on “61beb3783d6f42b902e6a124914d8137.safeframe.googlesyndication.com”?
You can change which websites can download files in Websites Preferences.

As evident, never grant the permission, regardless if it seems to pop pup when you are visiting a legitimate website.

Tpc.Googlesyndication

It is important to note that Tpc.Googlesyndication popup may show up on a legitimate site. Since the behavior is not typical, users may believe that the site was hijacked by malware, which is only partly true. Website developers can not control this behavior, as it affects every website that is using Google for serving ads.

Users said that “container.html,” otherwise known as Googlesyndication Safe Frame container, is asked of them to be download. While this is an HTML file and is most commonly harmless, no downloads should be proceeded with. In other words, you should remove Tpc Googlesyndication offered file by pressing Cancel on the pop-up.
