Download Norton Virus Definitions

 Any security software applications are vulnerable if the virus signature database is not up-to-date, which might result in infections of the hosting system. Reputable antivirus and protection tools enclose a built-in definition updater to make sure users get the latest signatures, provided their PC is connected to the Internet.

However, even if an Internet connection is not available, having the signature database updated is a must. Specifically designed for such situations, Norton AntiVirus Virus Definitions deploys a package containing the latest virus signatures issued by Symantec, which can be manually installed for various security products.

These virus definitions are applicable to all Symantec security software utilities, such as Norton Security, Security with Backup, AntiVirus / Internet Security, 360, Endpoint Protection, Protection Engine, Mail Security for Domino, and Mail Security for Microsoft Exchange. You just have to make sure you get the right package for your system's architecture (32 or 64-bit) and Symantec product version (see the Features section for more info about the External mirrors).

COMODO Antivirus is strong security software that scans your computer and removes any malware, viruses, or spyware that has infiltrated your system.

The antivirus system allows you to run a scan of the entire drive, in critical areas alone or according to your preferences. Other options include scanning only for spyware or scheduling daily or weekly scans.

A log file allows you to view all antivirus events and notifications, while the scanner settings allow you to adjust the level of real-time scanning (on access, disabled).

Defense+ is a section of COMODO Antivirus where you can add or remove files to or from your local safe executable files database, run a program inside Sandbox, view a list of unrecognized files that are automatically placed inside Sandbox until further notice, set various rules (e.g. predefined policies, blocked files) and configuration options (e.g. security level, execution control level, Sandbox security level).

Avast Free Antivirus

 The antivirus solution from developer AVAST Software comes in many flavors and most users opt for the free edition for obvious reasons. This does not make it any less reliable, however. The program features intuitive, advanced, and customizable scanning methods along with other modules dedicated to computer safety.

The installer is completely configurable when it comes to shields (for files, emails, and web), security tools, and preferred languages. Since it is ad-supported, the utility offers to install unnecessary third-party components but they can be skipped.

The security tools include browser protection and cleanup (e.g. Internet Explorer, Google Chrome, Mozilla Firefox), software updater for other programs installed, remote assistance for access on other computers, SecureLine for connection encryption against spyware via VPN, GrimeFighter for system cleanup and maintenance, Rescue Disk for worst-case scenarios with malware-crippled PCs, and a simple management connector that reports the Avast status to COM monitoring software.

Avast is wrapped in a pleasant and easy-to-use interface which provides fast access to the av status, scanning methods, tools, portable devices with Avast installed for remote control (smartphones, tablets), statistics (real-time and historical data, component status), as well as the rich configuration area, and animated tray icon based on different events.

It is possible to perform a quick scan in areas where malware is known to hide, complete by taking into account the entire computer, in removable drives only, custom directories, or at every Windows boot in autostart processes and services.

It is not necessary to change any settings, since Avast has a pretty decent default configuration. But advanced users have the possibility to fiddle with options regarding rootkits, file types, the exact scan areas, heuristics, PUP and suspicious files, archive formats, action on malware detection, scan priority, reports, exclusions, and scan scheduling.

Unconfirmed suspected infections sent to the quarantine may be investigated to decide whether to keep or eliminate them, while reports with scan activities may be examined in logs.

Download Opera for Windows

 Opera is one of the most popular modern browsers all over the world (together with Firefox, Chrome, and Edge), and its reputation has been established throughout numerous years of research into improving its stability, security, and feature-set.

Just like all the other mentioned browsers, you can visit websites, add bookmarks and explore the download history, as well as install extensions, however, there are some elements that help make Opera stand out.

This browser aims to make things as simple as possible not only for experts, but also for novices, and this is why it packs several tools that are meant to make their lives easier.

For example, Opera packs integration with WhatsApp, Facebook Messenger, and Instagram, so you no longer need to run third-party apps or keep several tabs open for web-based clients.

You also get a built-in weather forecast that displays the details about your chosen location (it can be disabled with ease if you are not pleased with it). You can also replace the default browser wallpaper with one of the available options or a custom image of your choosing.

In terms of user security, Opera researchers try their best to keep the user safe without restricting any actions, so all the features are not intrusive in any way, you just set them once and they run in the background.

This is the behavior for the ad blocker and tracker blocker, as they do their job without constantly showing which data they blocked, yet tech-savvy users can still examine it if they need to.

As for the integrated VPN, it comes in handy when you want to access online content that you are banned from because of your geographical location. Unlike dedicated third-party solutions, you do not get a limited amount of data you can use, so you can enjoy its features without any limits.
