Once running, bpcheck.exe is practically a ghost. It uses minimal RAM (often under 10 MB) and zero CPU unless you actually print something. It wakes up, checks if your Brother printer is still breathing, and goes back to sleep. No pop-ups, no ads, no “ink low – buy now” nagging (most of the time). If you’ve ever cursed a printer for going offline for no reason – this little guy is the reason it doesn’t happen as often.
There is no public evidence that the legitimate bpcheck.exe sends personal documents to China. However, due to privacy laws (China’s Cybersecurity Law), some enterprises and privacy-conscious users avoid Baidu software. It is classified as "potentially unwanted" but not technically "spyware." bpcheck.exe
