GSafe is an adware program that modifies your Web-browsing settings to facilitate displays of additional advertisements. Since this feature provides few or no benefits to your browser and may endanger it with exposure to third-party content, malware experts normally recommend uninstalling GSafe, like all adware. This line of conduct is especially recommended for unwanted software without reputable company backing, as is the case with GSafe and its illusive publisher, Genco Labs LLC.

All that's Unsafe about GSafe Advertisements

GSafe is adware distributed without a company website or standard marketing campaign, and further information on its development team has remained scant. GSafe, as a likely variant or spinoff of AdPeak (also identified as ScorpionSaver), is most likely to be installed through bundles with other downloaded programs. Free software sites and software piracy networks are some of the most common distribution methods used by such Potentially Unwanted Programs.

GSafe displays pop-ups, injected banners and other advertisements automatically, and may not always identify its advertisements as distinct from original website content. These advertisements may distribute disguised attacks, phishing tactics and other hoaxes, which makes even non-interactive contact with them inadvisable. However, not all GSafe advertisements may be equally threatening, and many may format themselves as online coupons and other forms of shopping-based discounts.

Opting Your Browser out of the GSafe Lab Experiment

GSafe is categorized as a Potentially Unwanted Program, although many PC security programs misclassify GSafe as a threat, as a result of its suspicious functionality and poor company history. Aliases of GSafe that malware experts have verified include Trojan.Win32.Triosir.dgibtv, Win32.Adware.Adpeak, PUA.Trioris, Trojan.Win32.Triosir.dgibtv and W32/A-07794f8f!Eldorado. GSafe's known versions have been confirmed for their compatibility with Internet Explorer, although the possibility of GSafe modifying other browsers still is open to investigation.

Improper deletion of GSafe may cause your browser to continue to load advertisements, even when the offending software is gone, which typically is the result of invasive changes in the system Registry. Since modifying the Registry carelessly may cause further harm to Windows, malware experts recommend nothing other than specialized anti-adware products whenever you need to remove GSafe from your browser.

Despite their naming similarities, GSafe's publisher and developer, Genco Labs LLC, is unrelated to the GSafe LGBT rights organization. All research by malware experts to date has led to the conclusion that Genco Labs LLC most likely is a dummied organization. This company merely may be a 'safe' name for GSafe's certificate authentication, without offering any of the real safety that software certification is meant to provide.

As usual for adware of any type, anti-adware tools can scan downloaded files that could install GSafe, and identify the bundle-installer platforms often used for such PUPs. However, PC users who are canny enough to avoid unsafe torrents, risky freeware domains and other, common PUP sources should be unlikely to experience an unasked-for installation of GSafe, in any case.
