What is OpenCandy? And how does it work?

OpenCandy is a dubious program that’s been classified as an adware and a potentially unwanted program by security researchers. It is created by SweetLabs and is designed to work on various browsers like Mozilla Firefox, Google Chrome, Internet Explorer, and more.
OpenCandy is actually a Windows executable file which was first noticed way back in November 2010. Up until now, this ad-supported program is still present on the internet and is distributed via software bundles. The software module of this program contains a Microsoft Windows library that can be hidden under any Windows installer. When you install this program, if you open the Task Manager, you will see certain processes, namely, spidentifier.exe and rundll32.exe – both of which are the process of OpenCandy.
Upon installation of OpenCandy, apart from the aforementioned processes, you will also notice additional components in your affected browsers which can lead to the sudden appearance of intrusive advertisements whenever you browse the internet. What’s more is that it also spies on your every online activity so it can harvest a couple of information which includes your browsing history, websites you visit often, ads you’ve clicked, search queries and more. The harvested information will then be used and even shared with third parties to deliver more sponsored content. You should be careful as some of these sponsored contents could redirect you to shady websites such as websites offering free software downloads, websites that urges you to participate in an online survey requiring your personal information and even websites that displays a scary alert telling you that your computer is infected with some malware and asks you to call some fake tech support number. If you happen to be rerouted to such sites, you must close your browser right away to prevent any potential security risks.
How is OpenCandy distributed over the web?
Like the most ad-supported program, OpenCandy is distributed via software bundles that are found on free sharing sites. It is added as one of the extra components in a free software package that also gets installed when you only use the quick or standard setup during the installation. To prevent unwanted programs from getting installed without your permission, you must always use the Advanced or Custom setup every time you install a free software package.
