A simple yet useful antivirus program

Baidu Antivirus is a renowned antivirus program developed by one of the largest companies in China. The latest version of the program is available in the English language and keeps your PC protected against a range of online viruses. With good customer support, the company is always open to feedback, which is used to improve subsequent versions. Compared to Avast Free Antivirus, 360 Total Security, and AVG Antivirus Free, this tool comes with a simpler interface, letting you get started without much trouble.

Baidu is one of the most efficient Windows antivirus programs. The program doesn’t have any glitches and runs smoothly on multiple versions of the Windows operating system. In case you come across certain issues, you can receive help from a huge community via forums. The only drawback with this antivirus download is the lack of pop-up alerts on scan completions.

Keeps your PC protected against online threats

Baidu Antivirus comes with full-fledged scans, checking your entire PC. The program supports quick scans for a range of issues and lets users execute custom scans for specific problems. In addition to this, you can expect real-time protection with advanced features, including proactive defense, file system protection, hard disk storage protection, and web access protection. However, most of the advanced features require some level of technical knowledge or skills.

As mentioned earlier, this antivirus program comes with a detailed feedback window, letting you report errors, offer suggestions, and seek help from the community. In order to clarify the issues, you can also attach files or images. There’s even an option to include personal information, such as a Facebook profile, MSN account, or Gmail address.

What about the interface?

Baidu Antivirus features large-sized icons that are properly categorized for easy access. When you launch the application, you’ll notice specific buttons to choose custom, quick, or full scans. There’s an arrow tab on the right-hand side of the screen. It reveals the real-time protection button. You can use this to turn certain options on and off.

From the detailed ‘Settings’ menu, you can customize the antivirus download. It lets you schedule automatic scans, openings, and choose what happens to infected or quarantined programs. You can also specify how detailed the scans should be, ensuring better protection for your PC. 

The security software comes with a blue and white color scheme, making everything look sleek and clean. Each feature has an intuitive response and doesn’t need any bug fixes. It’s worth mentioning that full scans can take a good amount of time. Fortunately, they don’t really affect your system’s performance. 

What about the features?

Baidu Antivirus features multiple configuration options, letting users customize almost every aspect of the program. For instance, you can create a system tray icon, automatically launch the tool at startup, instantly bring up the main window, disable or enable real-time protection, run a quick scan, or toggle gaming mode.

There are three large buttons in the main menu, which give access to the program’s scanning modules. ‘Quick’ scan performs a fast cleanup of the computer’s hard disk. It looks for suspicious files in the PC’s most vulnerable areas, such as scheduled tasks, browser add-ons, temporary internet files, and system services. 

The ‘Full’ scan is meant to check for vulnerabilities in the entire system. It conducts a thorough investigation of the PC’s health and performance. On the other hand, a ‘Custom’ scan lets you choose the exact drives, folders, and files to scan. This feature of the antivirus program automatically excludes system files covered under a ‘Quick’ scan.

It’s important to note that the virus scanner can be personalized to look for specific file types. On default, the Windows antivirus looks for executable files, archives, and documents. However, it can take into account all kinds of file formats. You can even include specific file extensions and modify archive size. 

Considering threat detection, the program automatically resolves various issues and backs up files to the secure quarantine section. You can manually select the action for each threat. It can either be marked trust or delete.

In order to fully detect suspicious files, the antivirus download needs to be set on normal mode. While you can increase or decrease the level of security, a substantial increase can cause false positives.

Additionally, users can extend the scope of scans. For instance, Baidu Antivirus can look for cracker tools, keygen threats, PornDial, adware, risk utilities, and auxiliary risks. For virus scanning, the program uses the Avira engine. You can turn it off for real-time protection.

Does Baidu Antivirus offer real-time protection?

With the comprehensive security software, you can schedule scans in full or quick mode on a monthly, weekly, or daily basis. Moreover, almost every setting can be customized. For instance, you can disable the automatic turn-off of the PC after completion of the scan.

Similarly, you can deactivate the real-time guard at any point in time. It can be customized as per detection level to favor either comprehensive scanning or resource consumption. You can also set the program to auto-fix issues.

Baidu Antivirus comes with a full-fledged USB protection tool. This prevents your external storage devices from infecting the computer with malware. This feature can scan the device in automatic or normal mode, depending on user preferences. It’s also possible to disable the autoplay functionality of the USB.

What’s more? The security software can automatically scan zipped and executable files after downloading them on the computer. You can set the app to verify all kinds of files, and send notifications on threat detection.
