Cyclon Gems Virus

Also Known As: Context2Pro Ads
Type: Adware
Damage level: Medium

What is Cyclon Gems?

The Cyclon Gems (or Context2Pro) browser add-on claims to enhance the Internet browsing experience by displaying coupon ads when users visit online shopping websites. While such functionality may seem legitimate, be aware that the Cyclon Gems add-on is categorized as adware or a potentially unwanted application.

This plug-in infiltrates browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) through free software downloads using a deceptive software marketing method called 'bundling'. Cyclon Gems also causes diminished browser performance and intrusive ads.

At time of research, this potentially unwanted program (PUP) was distributed using the DomaIQ free software download clients (fake downloads, such as Internet browser updates, hacking tools, etc.)

After successful infiltration, Cyclon Gems generates coupon and full screen pop-up ads, and moreover, this plugin tracks users' Internet browsing activity by recording websites visited, search terms entered on search engines, clicks on social media pages, IP addresses, full URLs of web pages visited, operating systems, and other information.

Computer users who observe Cyclon Gems (Context2Pro) coupon ads when surfing the Internet have browsers infiltrated with Cyclon Gems adware. Therefore, you are advised to eliminate this software from your computer.

The Cyclon Gems browser extension is similar to other adware, which infiltrates browsers using free software downloads. Examples include, CoupAppV-Bates, PureLeads, and Trusted Shopper. These browser plug-ins add no real value and often cause serious malware infections and privacy issues.

To avoid installation of Cyclon Gems, or other potentially unwanted applications, express caution when downloading and installing freeware. Today, most free software download websites employ 'download clients' - small programs offering installation of advertised browser extensions together with the chosen free software.

Thus, reckless freeware downloading can result in adware infections. When downloading free software, check each step and decline installation of any promoted browser plug-ins. Internet users who observe Cyclon Gems ads whilst surfing the Internet should use this removal guide to eliminate this adware from their computers.
