Caused keyboard conflict and online certifcate problems. Junk program in my case. Using HP ZE5400
it works my wireless
Its 20kb. A general rule is that viruses and malware are usually 1mb or larger. This does not mean that everything 1mb and higher is a virus. Its harmless
Doesn't seem dangerous and doesn't effect my network, so probably safe to remove.
Wireless program, safe, no harm
I noticed this service keeps the BCMWLTRY.EXE process alive. In my case the BCMWLTRY.EXE process has a memory leak that consumed all the memory resources.
loaded for blue tooth operation
