Is Baidu an Antivirus Software or a Spyware/Malware?

[TempoMat]

I just found out how Baidu was installed.

It came on the computer through JDownloader.
The installer was still located in a sub folder of JDownloader's Temp-Folder

The file is "BavPro_Setup_Mini_115.exe" with the following characteristics:

File size: 1.23 MB (1,291,624 bytes)
Size on Disk: 1.25 MB (1,310,720 bytes)
File version: 4.8.0.1383
Description: Baidu Antivirus Mini Setup

The Dll that was blocking all uninstall attempts had "bavha" in its name and there were far more keys in the registry with the name BAV* in them than Baidu
