This section is a collection of comprehensive articles that will tell you all you should know about antivirus products, features you need to look for and even how to go about choosing one.
Common questions about how we test antivirus software and what to look for in a security product.
Most of the antivirus software we have assessed, such as McAfee Virus Scan and Panda Antivirus, include an inbuilt firewall engineered to protect personal information from being leaked to hackers when browsing the internet. However, some require an additional payment to unlock firewall features.
The price difference between standard antivirus and an internet security suite is typically under $20 per year — a worthwhile investment for 12 months of full protection.
Over the last three years, URL filtering and antiphishing threats have increased dramatically. Cybercriminals work continuously to create new malware to access your confidential information.
For companies offering standard and premium packages, the premium tier adds an extra protection layer that warns you when suspicious URLs are detected. Antivirus software with an antiphishing filter ensures your confidential information stays out of criminal hands.
The best internet security programs come with advanced spam filters to protect you from malicious users who use spam emails to collect personal information and install viruses. Our team of experts evaluates the effectiveness of each antivirus in combatting spam — check our reviews to learn how each product handles conventional and new-era spam threats.
Family filters and parental controls are essential if you have children at home. Their primary role is to prevent children from accessing inappropriate content online.
Many leading antivirus companies now build parental controls directly into their products. This is an important factor to consider when choosing antivirus software for a household.
Yes. PC manufacturers partner with antivirus companies to pre-install their software, but the default software may not be the best fit for your needs or level of protection required.
Simply uninstall the pre-installed software the same way you would any program, then install the antivirus that is right for you.
Yes. We maintain a database of over half a million bootkits, worms, Trojans, viruses, spyware, adware, keyloggers, and other malicious software. Over the years we have built a network of trusted sources that supply samples for testing purposes. We also deploy "honeypots" online to capture new threats including malicious phishing sites. The specific details of our testing methodology are classified.
eicar.org provides a safe test program designed to evaluate antivirus software without using real malware. It helps average and advanced users verify their antivirus is working reliably before a real threat strikes. Our screenshots show we periodically use this platform before writing reviews.
If you encounter any problem buying, downloading, or installing an antivirus program, first contact the manufacturer's support team. If their response doesn't resolve the issue, feel free to get in touch with us — we will work hard to find a solution for you.
There are three key differences:
Enterprise antivirus includes a central management interface allowing one administrator to scan multiple computers across a network. Consumer software only operates on each individual device.
Businesses purchasing in bulk receive differentiated technical support levels — some offering 24/7 year-round coverage with faster response times.
Enterprise licensing costs more per deployment but large organisations with 25+ PCs may actually pay less per device than consumer pricing. The added central management and enhanced support make enterprise software the ideal choice for most businesses. Contact us for a quote.
In the current highly digitalized world, owning a computer and access to the internet is no longer a privilege for a select group of people in the society but an essential need. The two help to facilitate communication and provide one with direct and easy access to information.
It is recommended to purchase and install good antivirus software that can protect you from cyber threats as you browse the internet as well as scan your computer for hidden viruses in your hard disk to stay safe.
Viruses, spyware, and adware are all malware that poses a significant danger to your security and privacy. Each of them has unique features and attributes that differentiate it from the rest.
A virus is a code that is discretely integrated into a program for download. Once you download and install the program on your computer, the virus replicates itself and spreads to other parts of the computer thereby reducing the efficiency and functionalism of the device. If not detected and removed early, the virus can corrupt stored files, format your computer, as well as randomly shut down your computer.
Spyware is malicious software that is installed on one’s computer or device secretly. It is considered one of the most dangerous forms of cyber-attack, as it bypasses the internet security firewall and collects personal information stored on the computer. The collected information is sold on the black market or used to request for ransom from the victims.
Adware is special software that is used to spread marketing popup ads. If your computer is infected with adware, you will see popups whenever you open a particular application, visit a website, or boot up the computer.
Today, malware or virus can infect your computer when you open an email, use a USB memory stick to transfer documents to and from your computer, or simply browse the internet. Fortunately, there is some excellent antivirus software that you can purchase and use to protect your devices from the common and modern viruses.
In a bid to stay abreast with the new viruses and malware that are released into the general public, the antivirus companies scout the internet round the clock. A large number of the current antivirus software in the world runs on a robust signature database and an indexing cataloging system. It is of paramount importance to ensure that your antivirus is always up-to-date to protect yourself from the emerging viruses.
The standard antivirus software provides users with three options when a threat is detected. You can ignore, delete, or quarantine it. Deleting is effective in getting rid of common viruses, but the advanced ones such as Trojans will not go away even after multiple deletions. The ideal way of dealing with Trojans is quarantining. By choosing the quarantining option, the threat is transferred to an isolated and secure folder where it cannot cause any damage to the computer files.
The antivirus software is either active or passive. Passive means that one has to make scheduled or manual virus scans. An active antivirus is programmed to run in the background whenever the computer is turned on thereby providing comprehensive protection when working offline or online on the computer or using the mobile device.
The vast array of antivirus software in the market gives the consumer an opportunity to compare different types before making the final decision. However, the many features, offers, functionalism makes the selection process daunting and overwhelming. It is recommended to choose an antivirus whose features resonate with your internet security needs and preferences.
Some of the companies also offer free antivirus options to their consumers. While these will not cost you money, they are not as effective as the premium paid antivirus software. For instance, some lack an internet security feature.
The tasks that you carry out on your device or your line of work should guide you through the selection process. If you are always, working online, antivirus software that has an inbuilt internet security feature is an ideal choice. If you use emails to communicate with friends, colleagues, and clients frequently, go for antivirus software that offers anti-spam, spyware, and phishing protection.
Parents and guardians should look for software that has parental control features while gamers should select a security program that has a gaming mode that set the internet security software to use fewer resources.
