What is pubads.g.doubleclick.net?
doubleclick.net is a legitimate advertising service provided by Google, however, some cyber criminals use the pubads.g.doubleclick.net site to force users to visit various other adware-type websites. If you encounter these redirects or pop-ups (or other ads) that open with pubads.g.doubleclick.net, adware or browser hijackers have probably infiltrated your system.
More about pubads.g.doubleclick.net
In this case, pubads.g.doubleclick.net is used to promote the Speedup PC 2018 computer repair tool that supposedly fixes Windows errors. It is stated that, over time, most computers begin to suffer stability problems that can result in PC errors and other issues, mostly relating to Windows registry.
To avoid these problems, software is offered for download, which supposedly fixes computer crashes and errors, cleans the registry, and tunes up the entire system. Users wishing to download this software are encouraged to pay for the 'full version', but it will be downloaded together with other unwanted applications or even malware.
If pubads.g.doubleclick.net redirects you to websites promoting 'useful software', or you arrive at pages containing ads, check your browser or operating system for unwanted/suspicious programs or plug-ins, and scan the entire system with reputable antivirus software.
Unwanted pop-ups are often delivered by adware-type software or browser hijackers. Adware-type software delivers coupons, banners, pop-ups and various other intrusive advertisements. These are displayed using tools that enable placement of third party graphical content on any site.
The ads often conceal underlying content of any visited website and diminish the browsing experience. Furthermore, they usually lead to untrustworthy websites or even execute scripts designed to download and install potentially unwanted applications or even malware.
Browser hijackers, on the other hand, make changes to browsers by reassigning the new homepage, search engine, and new tab URLs. Users then start to encounter redirects to untrustworthy or malicious websites.
Furthermore, most browser hijackers collect data, such as IP addresses, keystrokes, URLs of visited websites, geo-locations, pages viewed, search queries, and so on.
Collected data might contain personal or sensitive data. The developers of these browser hijacker sell private information to third parties (potentially, cyber criminals) who misuse it to generate revenue. These applications can lead to privacy issues or even identity theft.

Conclusion
Adware and browser hijackers are potentially unwanted applications that supposedly provide "useful" features, however, they provide none of the functionality promised and are designed only to generate revenue. These applications only cause problems relating to users' online privacy or browsing safety.
How did adware install on my computer?
Adware and browser hijackers are often installed through intrusive advertisements or when software developers use a deceptive marketing method called "bundling" to trick users into installing potentially unwanted applications together with regular software.
They do not disclose information about the presence of this extra software and hide it in "Custom", "Advanced" and other similar settings or options of the installation processes. In many cases, users simply skip the installation steps without checking the settings/options. This behaviour often results in unintentional installation of various potentially unwanted applications.
How to avoid installation of unwanted applications?
Download software using official, trustworthy sources and direct links. Do not use third party downloaders, torrent clients, or other similar sources. Be cautious when installing software - do not skip installation steps without checking "Advanced", "Custom" and other additional settings/options.
Make sure that you opt-out of any additionally-included software (potentially unwanted applications), and only then finish the installation. Be careful when choosing which ads to click (if any), especially when visiting unknown/suspicious websites. Ads may seem legitimate, but some will redirect to gambling, adult dating, pornography, and other untrustworthy websites.
If you encounter these redirects, check your browser for unwanted/unknown extensions, add-ons, and plug-ins installed and remove them immediately. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
