What Makes This K7 Antivirus Review Different?

You might be wondering why you should trust this review over others. Well, I believe in hands-on testing and providing honest, unbiased opinions. Unlike some reviews that simply repeat information from the product's website, I've personally installed, used, and tested K7 Antivirus on my own devices.

For this review, I used a Dell XPS laptop with an Intel i7-1065G7 CPU and 16 GB of RAM, running Windows 11. I spent several days investigating every aspect of the software, running multiple scans, and testing its various features. I've captured numerous screenshots to give you a visual tour of the software, so you can see exactly what to expect.

My goal is to provide you with a detailed, first-hand account of my experience with K7 Antivirus. I'll share both the strengths and weaknesses I encountered, helping you make an informed decision about whether this antivirus is right for you.

Buying K7 Antivirus

Before examining the details of K7 Antivirus, let's talk about the purchasing process. K7 Security offers three main products for home users: K7 Antivirus Premium, K7 Total Security, and K7 Ultimate Security. For this review, I opted for K7 Ultimate Security to test all the available features.

The buying process was simple. After clicking the "Buy Now" button on their website, I was taken to a cart page where I could choose my subscription details. Here, you can select the number of devices (1 to 5) and the subscription period (1 to 3 years).

One thing that surprised me was an offer for their K7 mobile security version. I expected this to be included in the Ultimate package, so it's worth noting that it's a separate purchase.

The checkout process was simple. I entered my personal information, including name, address, and phone number. Payment was quick and easy using my debit card. After completing the purchase, I received an order confirmation email with download links, an invoice, and other useful instructions.

Installation

Installing K7 Antivirus was quick and easy. I downloaded the installer from the link in my confirmation email. The setup file was 265 MB, which is a reasonable size for a comprehensive security suite.

The installation process itself was impressively fast, taking only about 10 seconds on my system. There weren't any options to choose from during installation, which might be a downside if you prefer more control over the process. However, it does make things simpler for less tech-savvy users.

Once installed, the program opened automatically, and I was notified that the K7 Google Chrome extension had been installed as well. This extension is crucial for some of the web protection features, so it's good to see it installed by default.

Interface

The user interface of K7 Antivirus is clean and well-organized. It's divided into four main areas: the Menu Bar, the Status Bar, the Notification Area, and the Frequently Used Tasks at the bottom of the screen.

The Menu Bar at the top contains four menus: Settings, Reports, Support, and Help. These provide access to various functions:

• The Settings menu lets you manage product settings.
• In the Reports menu, you can manage quarantined items, view system monitor events, and access general reports.
• The Support menu allows you to activate or renew your product, access your account page, and view registration details.

The Status Bar prominently displays the overall protection status of your system, such as "System is secured." This gives you an at-a-glance view of your security status.

In the Notification Area, you'll find information about the last update date and time, virus definition information, and your subscription status. This keeps you informed about the current state of your antivirus protection.

At the bottom of the main window, the Tasks section provides quick access to essential functions like Scan, Update, Backup, and Tools. The Tools tab is particularly interesting, offering access to various utilities like Registry Cleanup, USB Vaccination, and Virtual Keyboard.

While the interface is generally user-friendly, I did notice a few limitations. The main window isn't adjustable, and there are no themes to choose from. Also, you can't change the language of the user interface, which might be inconvenient for non-English speakers.

Major Features

Now, let's examine the major features of K7 Antivirus and see how well they perform.

Web Protection

Web Protection is a crucial feature in any modern antivirus, and K7 doesn't disappoint. You can access it from Settings > Web Protection. It comprises three main components:

1. Safe Surf: This protects you from websites that could harm your computer or steal sensitive information.
2. Safe Search: This enhances your online search results by placing Trust Indicators (icon annotations) next to search results.
3. Identity Protection: This feature protects your identity when surfing the web by prompting you when passwords are entered on non-https sites.

K7 Antivirus Web Protection settings include enabling safe surf, safe search, and ID protection

It's worth noting that Safe Search's icon annotations work on Google, Yahoo, and Bing when using Internet Explorer, Firefox, or Chrome browsers. The Identity Protection feature is limited to Internet Explorer and Firefox. For Chrome users, you need to have the K7 extension installed for web protection to work effectively.

To test the web protection for this K7 antivirus review, I accessed several test links across multiple browsers. Here are the results:

• WICAR: blocked 11 out of 13 threats
• AMTSO: blocked 12 out of 15 threats
• EICAR: blocked 2 out of 4 threats

These results are pretty good, showing that K7's web protection is capable of blocking a wide range of online threats. However, there's still room for improvement, especially with the EICAR test files. I achieved better results with antivirus solutions like McAfee and Kaspersky.

Scan

K7 Antivirus offers a variety of scan options to suit different needs. You can access these from the Scan module by clicking the Scan button at the bottom right of the main console.

The Scan options: quick, custom, complete, and more.

Let's look at each scan type in detail:

Quick Scan

The Quick Scan checks important drives and folders on your computer for viruses and other potential threats. In my K7 antivirus review tests, it was incredibly fast, taking just 10 seconds to scan 255 files. While this speed is impressive, it's also the fastest and least thorough quick scan I've ever seen, which might raise some questions about its effectiveness.

Custom Scan

The Custom Scan allows you to select specific drives, folders, or files to scan. This is useful when you want to check particular areas of your system without performing a full scan.

Complete Scan

The Complete Scan thoroughly checks your entire computer for threats. In my tests, it took about 15 minutes to scan 316,000 files and detected one threat - an adware program that I chose to quarantine. This scan time is quite reasonable for a full system scan.

Rootkit Scan

The Rootkit Scan looks for deeply hidden malware that traditional scans might miss. It took about 25 minutes in my tests for this K7 antivirus review, scanning 559,000 files without detecting any threats.

Vulnerability Scan

This scan checks for vulnerabilities in your system and provides steps to patch them. Surprisingly, it took only about two seconds to scan 848 objects on my system. While the speed is impressive, it does make me wonder about the depth of this scan.

The Vulnerability Scan results: 848 objects scanned in 2 seconds

Abnormal Changes Scan

This scan checks for critical registry modifications that could affect your system's security and functionality. In my K7 antivirus review tests, it finished in just one second and found no issues.

Tracking Cookies Scan

This scan looks for tracking cookies that could compromise your privacy. K7 found 7 cookies on my system, but none were deemed malicious.

The Tracking Cookies Scan results

Scheduled Scan

K7 Antivirus allows you to set up automatic scans at specified intervals. This ensures regular checks without manual intervention.

The Scheduled Scan setup allows you to select folders to scan first.

Overall, K7 Antivirus offers a comprehensive set of scanning options. While some scans are impressively fast, it's important to balance speed with thoroughness for effective protection.

Ransomware Protection

Ransomware is a growing threat, and K7 Security addresses this with its ransomware protection feature. It works through the antimalware engine and a feature called Data Locker, which prevents unauthorized changes to your important files and documents.

To test the ransomware protection for this K7 antivirus review, I used a ransomware simulator. The results were decent, with K7 successfully stopping 11 out of 22 ransomware simulation scenarios. While this is not bad, it's worth noting that the average success rate among top antivirus solutions is around 15 out of 22.

Email Protection

K7's Email Scanner checks both incoming and outgoing emails to ensure no infected emails reach your mailbox. If an email contains a virus, the Email Scanner either deletes or quarantines the infected attachments.

The Email Protection settings include scanning options, advanced protection, and more.

You can configure the Email Scanner to start when your computer boots up and choose to scan both incoming and outgoing emails. Additional options include enabling worm blocking and protection against malicious attachments.

Antispam

The K7 AntiSpam feature identifies and filters junk emails by tagging them as spam. It continuously monitors your incoming emails and filters out unwanted ones.

In the Antispam settings, you can configure the phishing protection.

You can customize the AntiSpam feature by creating whitelists and blacklists of email addresses, display names, or domain names. You can also configure filters to search for specific keywords in email headers, subjects, or body text.

Device Access

The Device Access feature allows you to control access to USB, CD, DVD, and floppy drives. You can set permissions for file execution, modification, and copying, as well as configure automatic virus scans when devices are connected.

K7's Device Control settings include prompting for password before allowing access to your device.

This feature is particularly useful for preventing malware spread through removable devices and protecting sensitive data from unauthorized access.

Tools

K7 Antivirus comes with a variety of additional tools to enhance your computer's security and performance:

K7 Antivirus Tools: USB protection, registry cleaner, browser cleaner, and more.

• USB Vaccination: Prevents USB drives from being infected by autorun malware.
• Registry Cleaner: Scans and cleans the Windows registry.
• Computer TuneUp: Optimizes your computer's settings for better performance.
• Secure Delete: Permanently deletes files to prevent recovery.
• Various cleaners: For Internet Explorer history, Windows temp files, and Internet temp files.

• Virtual Keyboard: Allows you to enter data using your mouse, preventing keyloggers from capturing your keystrokes.
• Memory Booster: Frees up RAM by closing unused programs.
• Duplicate File Finder: Helps you find and remove duplicate files to free up disk space.

These tools add significant value to the K7 Antivirus package, providing a comprehensive suite for both security and system maintenance.

Backup

K7 Ultimate Security includes a backup feature to prevent accidental data loss. You can back up important files to various destinations, including CDs, DVDs, USB drives, local drives, external drives, or network drives.

The Backup window lets you set backups, restore files, deleted backed up files, and more.

The backup feature allows you to create multiple backup sets, each with its own rules defining what to back up, where to store the backup, and when to perform the backup.

Here's how a new Backup set is created

While not as advanced as dedicated backup solutions, this feature provides a useful additional layer of data protection.

Firewall

K7's firewall replaces the Windows firewall and provides proactive protection against inbound, outboun d, and program attacks. It works based on rules set for filtering traffic, including application rules, profile rules, network rules, and intrusion rules.

To test the firewall's effectiveness for this K7 antivirus review, I used a firewall test tool from grc.com. The antivirus solution passed this test, indicating that the firewall is effectively protecting against network-based threats.

Privacy Service

The Privacy Service feature allows you to safeguard your personal information, such as credit card numbers and email addresses, from being sent over the Internet accidentally or deliberately.

The Privacy Service allows you to create a list of trusted websites where info can be sent

You can add, edit, or remove private information and create a list of trusted websites where this information can be sent. This feature adds an extra layer of protection for your sensitive data.

Wi-Fi Advisor

The Wi-Fi Advisor is a valuable tool that warns you if your PC or laptop is connected to potentially unsafe wireless networks or hotspots. It provides information about your Wi-Fi connection's security status, classifying it as Safe, Un-Safe, or Protected.

You can also change the firewall profile for your Wi-Fi connection, adding an extra layer of security when connecting to public networks.

Parental Control

K7's Parental Control feature allows you to block websites and applications/games to protect your children from accessing inappropriate content. It can filter both http and https websites and even block third-party browsers from accessing the Internet.

You can use the Parental Controls window to manage computer users

You can create allowed and blocked lists of websites, set up ad blocking keywords, and establish application control. While it offers basic functionality, some users might find it less thorough compared to dedicated parental control solutions.

Gaming Mode

For gamers, K7 Antivirus offers a Gaming Mode. When enabled, virus alerts and updates run in the background, reducing interruptions during gameplay.

The Gaming Mode can be enabled via a small window where you can select the time period to postpone alerts

You can choose how long you want Gaming Mode to be active, ensuring you're not left unguarded for extended periods.

System Performance Impact

One of the key concerns with any antivirus software is its impact on system performance. In my tests using a Dell XPS laptop with an Intel i7-1065G7 CPU and 16 GB of RAM, K7 Antivirus performed well.

During a full scan, K7 Security consumed about 20% CPU power and 250MB of RAM. This is below the average CPU usage of 25% and RAM consumption of 300 MB for similar antivirus solutions. This indicates that K7 Antivirus is relatively light on system resources, which is a significant advantage.

K7 Antivirus Review: Conclusion

After thoroughly testing the software for this K7 antivirus review, I've found it to be a solid antivirus solution with several strengths:

1. Comprehensive Protection: K7 offers a wide range of security features, from real-time malware protection to email scanning and firewall protection.
2. Fast Scanning: The quick scan feature is remarkably fast, though this speed does raise questions about its thoroughness.

4. User-Friendly Interface: The interface is clean and easy to navigate, making it suitable for both beginners and advanced users.
5. Additional Tools: The inclusion of system optimization tools adds value to the package.

However, there are a few areas where K7 Antivirus could improve:

1. Limited Language Options: The lack of language choices for the user interface could be a disadvantage for non-English speakers.
2. Ransomware Protection: While decent, the ransomware protection could be more robust to match top competitors.
3. Mobile Security: The mobile security app isn't included in the main package, which might be inconvenient for some users.

Overall, K7 Antivirus provides good value for money, offering a extensive set of features at a competitive price point. It's particularly well-suited for users who want a simple, efficient antivirus solution without a significant impact on system performance.
