What is Avast Antivirus?

Avast was among the pioneers in offering a free antivirus plan. While recognized as one of the best free antivirus options, Avast extends its capabilities with premium plans, providing additional features and heightened security.

Today, Avast offers reliable protection for Windows, Mac, Android, and iOS devices, boasting an impressive user base of over 435 million worldwide. Its premium plans offer comprehensive defense, including advanced firewall protection and safeguards against spyware and other advanced cyber threats, ensuring robust security for your devices.

Is Avast Antivirus secure?

Experts in the cybersecurity domain regard Avast as a safe option.

In terms of performance, Avast stands out as a top choice for long-term usage, as its lightweight operations do not burden devices. Test results consistently demonstrate Avast's effectiveness in detecting and eliminating malware, with minimal impact on device functions such as file transfers and downloads.

However, there was disappointment among users when reports emerged that Avast had previously sold anonymized user data from free accounts to companies like Google and Microsoft before 2020. Avast has since implemented stricter privacy policies and increased transparency regarding its data logging practices.

Avast Antivirus subscription options and costs

While Avast may not be the most budget-friendly option available, it provides some of the most extensive plans in the cybersecurity sector. It offers two primary antivirus packages equipped to handle advanced cyber threats, along with various additional security tools. Additionally, there are several Avast One plans available, each offering supplementary features. Below is a brief outline of its pricing model and the features included. All paid plans are backed by a 30-day money-back guarantee, and users can explore features through the available free plans.

Is Avast Available for free?

Avast offers a complimentary plan featuring fundamental antivirus functionalities. The free plan entails real-time antivirus shielding, a WiFi vulnerability scanner, and ransomware protection. Additionally, the free version alerts users to any suspicious activities detected on their system and safeguards against phishing attacks.

Furthermore, Avast One Essential's free plan incorporates a VPN with a weekly bandwidth limit of 5GB. This exceeds the offerings of many other antivirus providers' free plans. However, Avast's premium plans are notably more dependable, delivering comprehensive protection. Users can access enhanced features for 360-degree security, with an Avast One Individual account available for just $4.19 per month.

Avast Antivirus protection capabilities

Every feature provided by Avast serves a crucial function in defending your devices against cyber threats. In this segment of our Avast assessment, we'll delve into the capabilities of these features.

Virus Scans

Avast provides an extensive array of virus scan options, with six different methods aimed at eradicating malware from the system. Here's what each virus scan type accomplishes:

• Smart Scan - Identifies malware, potentially harmful browser add-ons, outdated applications, performance issues, and network threats.
• Custom Scans - Allows you to schedule scans and determine which parts of your system to check, along with frequency and thoroughness.
• Full Virus Scan - Conducts a comprehensive examination of your system, scanning its memory and storage drives to detect malware.
• Explorer Scan - Enables quick scans directly from your desktop via File Explorer.
• Targeted Scan - Scans specific folders or external hard drives.
• Boot-Time Scan - Performs a scan on your device before the next system startup, enhancing the likelihood of detecting and removing malware.

Ransomware Protection

Ransomware assaults pose a severe threat, capable of locking your device and compromising all your data. Avast provides a dedicated Ransomware Shield feature, which blocks unauthorized modifications, deletions, or encryption of your documents and files.

It's important to note that while Ransomware Shield aids in preventing the loss of sensitive files, it cannot decrypt them in the event of a ransomware attack. Hence, activating this protection promptly is imperative.

Real-Time Antivirus Security

Opting for Avast's real-time antivirus protection over alternatives such as Microsoft Defender Antivirus brings several advantages. It continuously monitors your devices for any indications of suspicious behavior and promptly removes any detected threats.

This capability enables the program to address zero-day threats that haven't been previously recognized, with its knowledge base continuously updated in real-time based on emerging threats identified across its user base.

Network Inspection

Avast's Network Inspector is highly effective. It conducts scans of your network to identify vulnerabilities and security concerns, enabling you to safeguard your data and block unauthorized devices from accessing the network.

Capable of scanning both wireless and wired connections, Network Inspector can detect weak WiFi passwords, devices susceptible to attacks, and instances of DNS hijacking. It's an invaluable asset for any household, and you have the option to set it up to notify you when new devices connect to your network.

Email Guardian

Given the prevalence of phishing attacks, particularly those targeting financial fraud and identity theft via email, Avast offers Email Guardian as a solution.

This feature examines your emails upon opening and alerts you to any suspicious content labeled as "Suspicious." It is compatible with various popular email providers, including Gmail and Outlook.

VPN

Avast provides a reliable VPN solution called SecureLine VPN, which assists in unblocking geo-restricted content, securely downloading files from the internet, and evading third-party surveillance by hackers, governments, ISPs, and advertisers.

While it may not match the performance of top-tier VPN services, Avast SecureLine VPN offers decent connection speeds and the capability to unlock foreign Netflix libraries for streaming in 4K. With access to over 500 servers in more than 36 countries worldwide, the VPN is a dependable tool for accessing content from anywhere.

Avast AntiTrack

Avast AntiTrack enhances online privacy by obstructing third-party trackers and injecting false information into your digital footprint, making it harder for data brokers to collect meaningful information about you. This tracker blocker helps maintain privacy, prevents targeted ads, hides your location, and identifies tracking sources. Available on popular browsers such as Edge, Firefox, Chrome, Safari, and Opera.

BreachGuard

If you've browsed the internet without Avast or a similar antivirus program, data brokers may have already accessed your information. BreachGuard automates the process of sending removal requests to data brokers and follows up to ensure protection of your sensitive data. Additionally, it continuously monitors the internet and dark web for potential data breaches containing your information, alerting you if any are detected.

Avast's Webcam Shield safeguards your PC's webcam and microphone against unauthorized access by applications and malware. Activating this feature prevents third-party apps from capturing images, audio, or video.

The Webcam Shield offers three operational modes:

• Smart Mode - Avast automatically assesses the trustworthiness of applications attempting to access your webcam and microphone, blocking any attempts from untrusted apps.
• Block Access to Webcam and Microphone - Avast automatically denies access to your webcam and microphone for all apps and notifies you whenever an attempt is made.
• Strict Mode - Each app seeking access to your webcam and microphone must request permission. You must manually approve these requests before granting access.

Avast Cleanup

Cleaning up junk, duplicate, and outdated files on your PC might seem overwhelming. However, Avast simplifies the process with its Avast Cleanup PC optimizer, making it automatic with just one click.

We discovered that Avast Cleanup is highly efficient in eliminating junk files, broken shortcuts, and outdated applications. It features an automatic maintenance solution that routinely scans for new junk files and bloatware to enhance system performance.

Additionally, the PC optimizer allows you to identify app updates and manage startup apps, enabling you to remove unused applications. This can lead to significant improvements in startup speed and overall device performance.

Identity Theft Protection Features

 Included in the Avast One Platinum plan are various identity theft protection features, such as:

• Social media monitoring to alert you of any hacked or compromised accounts.
• Lost wallet assistance to help you cancel and replace lost credit, debit, and ATM cards.
• Credit monitoring, which tracks your credit file with three leading credit bureaus and notifies you of any changes.
• 24/7 personal support for addressing identity, fraud, credit issues, and technical concerns.
• $2 million identity theft coverage for lost wages, stolen funds, and expenses.

Privacy Advisor

Avast’s Privacy Advisor provides guidance on securing your online accounts and adhering to best practices for safeguarding your privacy.

Comprehensive step-by-step guides are available for various websites and apps, including popular platforms like Amazon, Twitter, Instagram, and Reddit. These guides detail the data collection practices of these platforms and offer recommendations on minimizing the disclosure of personal information.

Malwarebytes vs Avast

Avast holds several advantages over Malwarebytes. It provides protection for a broader range of devices by default, includes a firewall, and offers a free plan with significantly more features.
