SkypEmoticons is a Potentially Unwanted Program that may load advertisements in your browser or modify your Skype experience in negative ways. Although only a minority of PC security entities have flagged the SkypEmoticons website as a potential threat, malware experts have seen behavior from SkypEmoticons consistent with non-consensual distribution models. You should strongly consider deleting SkypEmoticons in all cases, which, as with most adware, is doable with proper PC security tools.

SkypEmoticons: an Extended Adware Experience

SkypEmoticons is a Potentially Unwanted Program that may install from SkypEmoticons.com, but, also may be introduced via the embedded links in its automatic Skype messages. Skype users who download SkypEmoticons may have their Skype instant messaging experience hijacked by that PUP, which may spam the victim's contact list members with links recommending its installation for using 'extended icons.' The wording of this message implies that SkypEmoticons is a default part of the Skype experience, although malware experts quickly verified that SkypEmoticons is a third-party, unsupported product. If you disable the automatic invitation settings that SkypEmoticons uses for sending these messages, SkypEmoticons will reactivate them automatically.

Along with its unusual distribution model, SkypEmoticons also includes functions for modifying your Web browsing experience. These features insert additional advertisements into unrelated HTML pages, and also may generate pop-up windows automatically. Most PC users found that a standard, manual removal of SkypEmoticons failed to remove the browser settings responsible for SkypEmoticons advertisements. Malware experts have associated a small number of SkypEmoticons installations (and incomplete deletions) with other issues, especially failures to login to your Skype account.

Using Skype with the Right Emotional Package

Because of their generic usability and seemingly harmless nature, emoticon add-ons are favored packages for the developers of Potentially Unwanted Programs. However, these PUPs, like SkypEmoticons, typically include other functions and unwanted side effects that may harm your computer (or the computers of your Skype contacts). Adware programs also may block any simple, manual uninstall attempts, which is a trait malware experts also verified for SkypEmoticons.

You can delete SkypEmoticons with any anti-adware application of your choice, after which you also may wish to either reset all relevant Skype and browser settings or uninstall and reinstall those applications. Until you confirm the removal of SkypEmoticons, advertisements loaded in your browser should be regarded with all the suspicion due to third-party content affiliated with disreputable business models. As a result of the natural vulnerabilities of script-based Web content, such advertisements may endanger even PCs whose users fail to interact with them deliberately.

Lastly, malware experts also would recommend speaking with any Skype contacts delivering SkypEmoticons-associated messages to verify that they're aware of the hijacking of their instant-messaging experience. In most cases, SkypEmoticons messages may not display in the conversations of the originating user, which can allow SkypEmoticons to distribute itself without the full awareness of those responsible for it.
