About AVG
The great news is that from the 2016 version there will be no more annual releases: the antivirus will be updated frequently, in the same way that happens with Internet browsers.
Antivirus
The most basic functionality of AVG monitors the operation of the computer in real time to avoid the action of viruses, spyware, Trojans and worms spread both online and offline, either through the Internet or through the use of external drives and pendrives. In the Pro version, it is possible to complement these functions with an encryption tool to password protect any desired file.
LinkScanner
Present in the free version of AVG, the application has a system to read links and Internet pages to avoid unpleasant surprises. With this feature enabled, the software reads the links placed on web pages to find threats, alerting the user not to click on possible sources of virus distribution. The paid version supplements these features with Online Protection. The function focuses on reading files downloaded from the Internet to find hidden viruses and prevent pests from running on the PC.
Identity protection
The function can be accessed through the "Identity" button and allows you to configure an interesting protection function against malware. IdentityProtection monitors the applications running on the computer to verify the behavior of each one. In the event of suspicious movements, the function immediately closes the focus of the threat. Thus, the tool ends up working as a complementary form of protection to the others.
Email checker
Even in the free version, AVG offers a protection component against the risks present in email messages. The function identifies the potential risks present in messages stored in the inbox, outbox and even in the spam filter. For those who opt for the paid version, there is an add-on to this service, Anti-SPAM. As the name implies, it is a tool dedicated to preventing debris from falling into your inbox. In both cases, there are several configurations to define the behavior of these resources according to the user's profile.
Firewall
As is common with such software, AVG also has a firewall. The idea of this type of resource is to create a natural block for hackers, especially in sensitive transactions, such as making purchases over the Internet and accessing bank accounts. However, this feature is restricted to users who decide to purchase the paid version of AVG.
PC analyzer
As has become common in this market, AVG also has a tool that promises to scan the computer for bottlenecks and problems that can slow down the machine. PC Analyzer examines the same trouble spots as dedicated software like CCleaner. The function looks for errors in the registry, shortcuts that go nowhere and orphaned files, in addition to performing the process of defragmenting the hard disk.
The free version of AVG is an option for those who want an efficient and simple antivirus, the type that the user installs and forgets. The program is responsible for monitoring the operation of the computer to prevent viruses and malware from causing problems, similar to the portable edition for Android.
In addition to conventional antivirus functions, AVG has the PC Analyzer, a function created to find errors, correct them and speed up the operation of the computer. In this sense, the option for AVG can be interesting since it can eliminate the need for an application dedicated to this task.
Those who decide to purchase the paid version gain access to a number of features that complement the software. There are tools that monitor the content of files downloaded from the Internet, which isolate spam in the inbox, in addition to a function that allows the encryption of the files that the user wants, imposing password protection to access them.
