Optional update mode In AVG antivirus technology, the realization of fast scanning function comes from the precise combination of layered detection functions in the program, which can filter files layer by layer before scanning, bypass unnecessary virus analysis, and detect infected parts more directly, quickly and effectively.

Known virus detection

The simplest detection technology, which can scan the existing virus identifiers in files (special byte sequences represent specific viruses); Then, on the basis of this detection, a detailed analysis is carried out to determine the accurate infection location.

Universal detection

This is a common detection of known viruses, which can be used to lock new varieties of known viruses. If no known viruses are found, the universal probe will look for the unique sequences of some viruses in the file. Even if the behavior of the virus after mutation is different from before, it can be detected because the internal sequence of the virus itself will not change. This technology can effectively detect macro viruses and script viruses.

Heuristic analysis

The third detection mode is heuristic analysis. The key of this method is to detect viruses outside the network virus database. In heuristic analysis, two commonly used methods are:

Static heuristic analysis: Start when searching suspicious data structures.

Dynamic heuristic analysis: AVG can open a document in the protected state of a virtual computer through coding simulation, analyze whether there are some typical behaviors of viruses in the document, such as searching for other executable files, and make modifications when running applications.

Based on behavior analysis

The fourth layer is the behavior analysis of virus detection. This patent-pending technology focuses on the behavior of software during execution. Using different classifications and advanced algorithms, this technology judges harmful behaviors of files and prevents them from being executed. AVG's social network protection technology is being patented, which is a new function of AVG 20 12. Links exchanged on Facebook and MySpace will be automatically checked in real time, so people, computers and networks on social networks will be protected. After installing AVG, AVG social network protection starts automatically without any specific account or application settings.

AVGLinkScanner & ampreg program (enhanced version)

AVG link scanner and. Reg, this is a cutting-edge technology and is applying for a patent. Surf-Shield will automatically check web pages in real time. This can completely protect against web-based attacks, which may only appear on the website for a few hours and then move to other pages. Link scanner & reg It also has search shields, search shields and common search engines (including Google, Yahoo! And Bing) and social networking sites display safety ratings in search results. Ratings are color-coded with icons to show which websites are safe and which are dangerous. AVG firewall protects you from malicious attacks by checking the communication on each network port. It can immediately stop all unauthorized access attempts, prevent intelligent intrusion, and make home and work networks (whether wired or wireless) more secure. AVG firewall can also prevent input and output attacks, which allow malicious software to take control of your computer and try to damage other people's computers. Every time an attempted connection is detected, the AVG firewall refers to the database of the trusted application. If it decides that the application is trustworthy, it allows communication to be established, thus reducing the interruption caused by pop-up windows. Conversely, if a threat is detected, it will automatically block all communication. This greatly reduces the possibility of losing any information before isolating the threat. For AVG 20 12, if the AVG application database is not used, the firewall warning device will suggest the measures to be taken.

The biggest advantage of using AVG firewall is that it is closely integrated with other components in AVG suite, which means that they complement each other and cooperate with each other to provide the most complete protection. It can be accessed through application plug-ins (including Microsoft Outlook and Bat! ) or through a personal email scanner. AVG email scanner runs at the level of POP3 and SMTP communication protocols, and can also protect the email communication of all other email clients.

AVG email scanning filters the extension or content of attachments.

The solution at the level of POP3/ SMTP communication protocol is not dominated by the e-mail client program used.

Protect multiple email accounts and check multiple email servers.

Support SMTP authentication

AVG intelligent anti-Rootkit technology, which supports secure (SSL) communication, will detect malicious software that tries to hide in the depth of the system. This technology uses the kernel of the operating system to analyze the user-level views and processes of the file system, and will report any inconsistent processes, because this may indicate the existence of a Rootkit. Updating can ensure that your installed AVG is the latest version, which is very important for effective virus detection. AVG anti-virus software provides you with several methods to ensure the latest status of the software, including a comprehensive automatic update program. We use professional servers to support global network services, and even when a large number of requests for downloading updates flood in, we can still effectively ensure that you get the necessary update files.

Main features:

The update file is very small (generally only a few tens of KB).

You don't need to restart your computer after every update.

Regular updates are released twice a week, and priority updates are released when necessary (when new viruses spread).

Updates can be initiated periodically or manually.

Support proxy server authentication

Registered users can receive AVG update emails and be informed of the updates.

When the download demand is high, it can still effectively provide an update file to automatically detect the network connection (if dial-up internet connection is used) and then automatically update it.

Check whether there are new updated files (AVG antivirus software and AVG management software) in the scheduled task.

Open the folder for manual update.

AVG antivirus software is a well-known antivirus software brand on PC platform, and this security software has fully entered Android system. Antivirus expert is AVG's security software specially developed for Android system, which can protect your Android phone from malicious software, viruses and spam messages.
