Simple , I've downloaded a 6000 virus test.rar for test it , It detected only one , I clicked solve it deleted the whole .rar , But , I was scared of me getting the infection still. After a reboot , Baidu pc faster had appeared , Unninstalled. Soon after that , I've got 2 MSYOSYNC.EXE running , And ending quickly , Making my windows cursor keep loading nothing.
And also , Due to fact bitdefender have anti-ransomware , Which is a virus i fear much.
[Off-topic]
Also looking for a new browser as i dont trust baidu products anymore
