Well Qihoo 360 has been around for like 20 years in China.
They used to make those computer optimize and clean software, later got into anti-virus and even browser (use Ie core and Chrome core)
They were considered absolutely spyware around 8 years ago, however nobody in China cares. Their software was really good, and literally everyone including their mom install 360 right after windows installation.
Yah i can’t really dig up those infos from decade ago, and I seriously don’t remember the details that people discovered in their 360 software that is concrete proof it is a spyware. If i remember correctly? They upload some zipped file periodically to their server, and someone cracked it open and it contains very sensitive info from ur computer? Even file names in your document folder and such?
yah so... i would avoid it, but we need concrete proof before we accuse a chinese company is spying for the government
