Reference: Based on Antivirus for Windows 7, test carried out by AV-TEST, February 2017. A Free Version of Antivirus Software also worth for consideration and available to download.
AV-TEST is an independent organization which evaluates and rates antivirus and security suite software for Microsoft Windows and Android operating systems, according to a variety of criteria. Every other month, the researchers publish the results of their testing, where they list which products they awarded their certification. The organisation is based in Magdeburg, Germany. The aim of the research work is to directly detect the latest malware, to analyse it using state-of-the-art methods and to inform customers of the top-quality results obtained.
Which is the best Antivirus for Windows 7?
Antivirus is abviously one of the smart way to secure your PC. This is one of the best computer protection. A proper install which is idealy after fresh installation of PC operating system such as Windows 7, can prevent from unwanted programs, scan, block, detect and destroy viruses, worms, trojan horses, spyware, malware, etc. There are so many antivirus software available in the world, you can download and use it for free.
A good antivirus is a must have to secure your PC. A few things you need to consider when choosing which is suite to your needs:
- Real Time Protection and Detection Technology
- Virus scanner and blocking technology
- Database of known virus and malware
- Speed and Performance
- Compatible With your PC Operating System
- Automatic updates
- Malware removal
- Other Features: Password Managers, System Optimization, Applications updates, Phishing protection, Antispam, Browser protection, etc.
Pick the antivirus software that consistently delivers the highest detection and proactive protection scores. After all, this is the only reason you’re getting antivirus software, to prevent and detect viruses.
There are many different types of Antivirus and they use many different ways to protect the computer, and because of this, Installing more than one antivirus is not a good idea. The 2 different types of antivirus can interfere or conflict with each other. Installed antivirus solutions, running on individual computers, although the most used, is only one method of guarding against malware.
Hardware and network firewall
Network firewalls prevent unknown programs and processes from accessing the system. However, they are not antivirus systems and make no attempt to identify or remove anything. They may protect against infection from outside the protected computer or network, and limit the activity of any malicious software which is present by blocking incoming or outgoing requests on certain TCP/IP ports. A firewall is designed to deal with broader system threats that come from network connections into the system and can be used for additional protection.
Cloud antivirus is a technology that uses lightweight agent software on the protected computer, while offloading the majority of data analysis to the provider’s infrastructure. Some examples of cloud anti-virus products are Panda Cloud Antivirus, Comodo, etc.
One approach to implementing cloud antivirus involves scanning suspicious files using multiple antivirus engines. This approach was proposed by an early implementation of the cloud antivirus concept called CloudAV. CloudAV was designed to send programs or documents to a network cloud where multiple antivirus and behavioral detection programs are used simultaneously in order to improve detection rates.
Parallel scanning of files using potentially incompatible antivirus scanners is achieved by spawning a virtual machine per detection engine and therefore eliminating any possible issues. CloudAV can also perform “retrospective detection,” whereby the cloud detection engine rescans all files in its file access history when a new threat is identified thus improving new threat detection speed. Finally, CloudAV is a solution for effective virus scanning on devices that lack the computing power to perform the scans themselves.
Some antivirus vendors maintain websites with free online scanning capability of the entire computer, critical areas only, local disks, folders or files. You may consider to analyze suspicious files and URLs for quick detection of viruses, worms, trojans, and all kinds of malware using VirusTotal. Periodic online scanning is a good idea for those that run antivirus applications on their computers because those applications are frequently slow to catch threats. One of the first things that malicious software does in an attack is disable any existing antivirus software and sometimes the only way to know of an attack is by turning to an online resource that is not installed on the infected computer.
