I had initially read many good reviews about this, so I installed it on my personal PC to replace Microsoft's security essentials (MSE). It was good and caught a lot of bugs that MSE didn't catch. So I decided to install it on all the PCs at the office. After a while networking became very slow till all PCs couldn't connect to the server and internet anymore. We hired IT people to check our networking to find no issues. It is only when we revived 1 unused PC that didn't have Baidu is when I realized it may be Baidu Antivirus causing the problem. After removing it from all my PC at the office, the networking revived and functionality came back to normal. It took three months and 2 IT guys and money to just realize it was nothing but Baidu Antivirus causing the problem on my network and office PCs.
