Update: The latest release of Baidu Antivirus is hardly a current one, so I do not recommend using it as your primary AV program. It might still be fine for downloading once and using for a malware scan, but don't use it as your sole virus fighter. If you're currently using this program, look through my list of better antivirus programs for a replacement.

Baidu Antivirus 2015 is a great free antivirus program due mainly to the fact that while its design is simple and easy to use, the program itself is rich in features.

My Thoughts on Baidu Antivirus 2015

My initial thoughts about Baidu Antivirus 2015 were overwhelmingly positive simply because it installed in less than 10 seconds! This is much quicker than the majority of similar products.

One great feature is the quarantine sandbox. You can open any file or program this way by simply right-clicking them and choose the appropriate option from the menu. Doing this will let you open viruses (or files you think are malicious) without giving them the ability to affect your computer.

I like that Baidu Antivirus protects not only against threats from USB devices but also from phishing attempts. You don’t normally see webcam protection in an antivirus program, so it’s nice that Baidu Antivirus 2015 includes this feature, too.

The traffic monitor is a really nice addition to Baidu Antivirus 2015 because if you suspect a program may be malicious or is simply using too much bandwidth, you can view it in Windows Explorer, abruptly shut it down, or even block it from the network.

Baidu Antivirus' password protection feature can be setup to prompt for a password if a specific task is attempted to run, such as changing program settings, disabled defenses, exiting the software, and/or uninstalling the program, among others. This is really useful to prevent viruses (or other users) from disabling Baidu Antivirus.

In addition to the above, I like that you can customize the settings such that one of a dozen images can display as the background for Baidu Antivirus, as well as automatically scan downloaded executables, compressed files, every file, or nothing.
