Hi,
almost all software you use will use many components -some supplied by the system, many written by the developers of that software, and some written by third parties - who may be companies or individuals, and the components software may be open or closed source.
In this case, Style Master uses a very commonly used third party component by VBAccelerator, which provides the functionality to browsers and select folders as well as files on Windows.
You'd find hundreds if not thousands of pieces of software use this component. Sadly, so too does some malware. So, in their "wisdom", some "security" companies decide that since this is a component used by some malware, it is evidence of malware, and removing it will stop the malware in question working. Which it does. But also it stops a lot of legitimate software too.
Sometimes the situation is worse - Norton Security flags the use of some system functionality, which even Microsoft uses as a security problem - because it is also commonly used by Malware.
So, it is worrying for users, and it is frustrating to say the least for developers, which is why I use the term security in quotes - it seems like in other spheres of our lives these days, these companies are more interested in security "theatre" rather than real security.
Now, that's not to say that we don't take these issues seriously - we do, and always try to address in detail any such issue.
One great site to visit for security issues - whether computer, airport, banking, and many more is Schneier on Security

Thanks again for flagging this, and hopefully others who might see this problem in future
