Wholehugewords.com ads can come in the form of pop-ups, banners, redirects, additional layers on the screen. The content promotes other potentially unwanted applications and tries to get exposed users to third-party material related to the sponsors of the advertising campaign. Those companies and thrid-parties can be malicious, and the developer of this adware is not responsible for the content users get exposed to due to the reroutes and advertising materials shown when the PUP is active.
You might call the program a Wholehugewords.com virus, but there is nothing malicious that is directly related to the advertisements or redirects, direct desktop push notifications. Nevertheless, any random page is possibly accessing the details about your online browsing habits and can lead to really dangerous sites and malware-laden pages. This is the reason for you to remove the PUP right now. If you wait, the machine can get significantly damaged, and privacy issues get more significant.
