Avast Premium Security is an application that helps protect your devices from viruses, malware, phishing, and other threats. It scans your online mailboxes for suspicious emails, as well as control which IP addresses can remotely access your PC and helps block all other connection attempts.
Avast Premium Security (Multi-Device) comes with all the features included in Avast Premium Security (single-device), and additionally includes Avast Premium Security for Mac, Avast Mobile Security Premium for Android, and Avast Mobile Security for iOS for use on up to 10 devices simultaneously.
Avast Antivirus comes with several predefined scans as well as the option to create your own custom scans. Generally, running a scan does not noticeably affect system performance. However, performance may be affected somewhat depending on your system configurations, especially if you execute multiple scans simultaneously.
Avast Free Antivirus automatically activates after installation. However, after 12 months, the application may prompt you to renew the activation. To continue using Avast Free Antivirus, refer to the following article for instructions:
You can activate an Avast Premium Security (Single-Device) subscription on one device at a time, and transfer this subscription to another device on the same platform. For detailed instructions, refer to the following article:
Core Shields are the main protection components in Avast Antivirus. By default, all Core Shields are enabled to help provide optimal protection. The Core Shields are comprised of the following shields:
Quarantine is an isolated space where you can store potentially dangerous files or send them to the Avast Threat Lab for analysis. Files in Quarantine cannot run or access your system and data, so any malicious code contained within a file is unable to harm your PC.
CyberCapture is a feature that helps detect and analyze rare, suspicious files. If you attempt to run such a file, CyberCapture locks the file from your PC and sends it to the Avast Threat Lab where it is analyzed in a safe, virtual environment.
Network Inspector scans your network for vulnerabilities and identifies potential security issues that open the door to threats. This feature checks the status of your network, devices connected to the network, and router settings. Network Inspector helps you secure your network to prevent attackers from accessing it and misusing your personal data.
Ransomware Shield helps secure your personal photos, documents, and files from being modified, deleted, or encrypted by ransomware attacks. This feature scans for and helps secure folders that may contain personal data, and allows you to specify which other folders you want to protect from untrusted applications. Additionally, you can specify which applications are allowed to modify the files in your folders and which applications are always blocked.
Firewall monitors all network traffic between your PC and the outside world to help protect you from unauthorized communication and intrusions. Firewall can prevent sensitive data from leaving your PC and can block attempted intrusions by hackers.
You can also set the application rules to control network and internet communication for specific software applications. Firewall applies these rules whenever a particular application tries to establish a connection to the internet or with another network.
Hack Alerts continuously monitors the dark web and warns you if your login credentials have been leaked online. The dark web is a more private part of the internet that can only be accessed with an anonymizing network like the Tor browser. The extreme privacy offered by the dark web makes it the ideal environment for criminals to illegally buy and sell leaked personal information.
Software Updater is a feature in Avast Antivirus that keeps commonly used third-party software up to date to eliminate potential security risks. Malicious threats or attackers often use leaks in outdated software to access your PC. Software Updater displays the most popular programs installed on your PC and allows you to easily update them.
Bank Mode, available in Avast Premium Security, is a protection feature that provides a virtual desktop that acts as a clean, safe PC within your real PC. The Bank Mode virtual desktop helps protect you against the injection of malicious scripts, keystroke logging, and screenshot attempts by third-party apps. We recommend using Bank Mode each time you want to access a banking website or pay online.
Remote Access Shield is a feature available in Avast Premium Security. Remote Access Shield allows you to control which IP addresses are allowed to connect remotely to your PC, and blocks all unauthorized connection attempts.
Real Site, formerly known as Secure DNS, is a feature in Avast Premium Security. Real Site helps secure you against DNS (Domain Name System) hijacking. Some malicious programs can stealthily redirect you from an authentic URL to an inauthentic one to acquire sensitive information such as usernames, passwords, and credit card details.
Every time you enter a website's URL (address), such as www.example.com, into the address bar of your browser, the URL is translated to the IP address (Internet Protocol address) of the web server where the web page that you want to access is stored. Real Site provides an encrypted connection between your web browser and Avast's own DNS server to ensure that the displayed website is the authentic one.
Sandbox, available in Avast Premium Security, is a virtualization tool that allows you to browse the web or run an application in an isolated and safe environment. When you run an application in Sandbox, your activity and web content is contained, which prevents damage to your PC. This is useful when you want to run suspicious or untrusted applications without risk.
Browser Shield, available in Avast Premium Security, helps secure your passwords stored in your web browsers. If left unprotected, passwords stored in web browsers may be vulnerable to malware and theft by unwanted applications. Browser Shield allows you to choose which apps have access to your saved passwords. Browser Shield also blocks access to browser cookies to protect your personal and sensitive data.
Webcam Shield, available in Avast Premium Security, helps prevent applications and malware from accessing your PC's webcam without your consent. With Webcam Shield enabled, untrusted applications should not be able to capture images or videos and send the content outside of your PC to compromise your privacy.
Sensitive Data Shield, available in Avast Premium Security, scans and helps protect your sensitive personal documents against unauthorized access and malware. The files considered sensitive contain your personal information that, if revealed, can compromise your privacy and identity. Sensitive Data Shield controls which applications and users have access to your files to secure your private data.
When you erase a hard drive, or delete a file using standard tools, only a reference to its data is removed from the file system. Simply deleting sensitive files, such as user data or licensed software, may not be safe as there are tools capable of restoring deleted files. Data Shredder overwrites files with meaningless data multiple times before deleting them which prevents data from being recovered. Data Shredder is especially useful when selling/donating your computers or hard drives.
Passive Mode disables all active protection, such as Shields and Firewall, so that you can use more than one antivirus program at a time without interfering with the performance of your PC or the reliability of antivirus detections. In Passive Mode, Avast Antivirus receives all virus definition and program updates, which allow you to manually run scans to check for issues on your PC, however, Avast does not actively protect you.
Your specified file, folder, or website is now listed on the Exceptions screen. To remove an exception, hover your mouse over the listed exception, then click the trash can icon that appears on the right.
Avast uses a database of known virus definitions to identify malware and other threats on your PC, so it is important to ensure virus definitions are regularly updated. By default, Avast updates virus definitions automatically. However, Avast cannot perform the update if you are offline.
Any threats detected during a scan are sent to Quarantine by default. After running a scan, you can access Quarantine from the results page. Quarantine is an isolated space where potentially dangerous files are safely stored. From Quarantine, you can also perform specific actions, such as sending suspicious files to Avast Threat Labs for analysis.
Yes. Microsoft Windows Firewall is not necessary when using the built-in firewall included in Avast Premium Security. Avast Firewall monitors all communication between your PC and outside networks and blocks unauthorized communication. It is highly recommended to keep all Avast protection components enabled at all times for reliable PC protection.
