Why do I need Antivirus Software?

If you follow the tech news carefully, you know that cyber-criminals are increasingly targeting customer sensitive data. Also well-known companies are dealing with data theft at an increasing rate. With ransomware exploits such as Locky or TeslaCrypt surfacing more frequently in recent years, protecting your personal data is vital.

Therefore everyone using a PC needs to have antivirus software installed on it. People, who use their computers occasionally, only for a few purposes like checking e-mails and browsing the internet, often think that they do not need any antivirus protection for their systems. In fact, it is not true.

What are the advantages of an Internet security suite?

Internet Security is a software package that groups together several tools to protect your computer from various online threats.

With new ingenious anti-phishing tools, Internet security software can protect your privacy and personal data. In addition to a virtual keyboard, every good security packages will come with protection against ransomware.

Even on the move, an Internet security suite ensures protection. When logging in to a public Wi-Fi network, it checks if the connection is secure or if there is any risk of your data being exposed.

Most internet users use their computers for online shopping and banking. This involves sending sensitive data over the network. Merchants use different security methods such as SSL encryption to protect this data. But this doesn’t guarantee a one hundred percent protection rate. Internet security suites protect the data typed using a protected browser, so it’s secured against any potential keyloggers programs.

Your children will also use computers browsing around the Internet. After all, the World Wide Web offers many games and learning opportunities for the little ones – but not only. An Internet security suite with several child protection settings ensures that adult content is blocked. In addition, the software can keep track of the young’s online activities and block any careless disclosure of personal information.

Antivirus protection can eat up a lot of system resources while running in the background. A good Internet security suite should work unobtrusively without the PC user noticing. Some suites even offer optimization tools or use the cloud to scan suspicious applications, thus conserving your local system resources.

Free of Paid version?

A simple search is enough to find several antivirus options that are available for free. Also, well-known security software manufacturers such as Kaspersky, Bitdefender, or Avast also offer a free version of their antivirus scanners. These provide very basic protection but are far from the performance of their paid versions. This is why you should not be misled by the actual efficiency of the free versions.

The free version from a well-known provider or even the trial version is suitable if you just wish to test the security program before making a purchase. In the long run, free security software does not provide adequate protection against the current cyber threats.

In order to get reliable protection against malware, you don’t necessarily have to dig deep into your pockets. The above comparison of the best antivirus security programs shows that even in the lower-priced ones come with many powerful Internet security tools.

Does Mac OS need Internet security?

Malware attacks on Mac OS computers have been very rare before 2016. This is because Apple equips its operating system with several security components. These include Gatekeeper, Sandbox, and the Xprotect download protection unit.

A security package will usually add the file quarantine feature which controls the files that what programs download from the Internet. This affects, among other things, the Safari browser and the e-mail default application. Overall Apple’s notebook is one of the safest PCs on the market.

Many Mac users argue that Mac OS does not require any external security or antivirus program. However, most IT security experts urge consumers to take precautionary measures. As more and more users switch to Mac OS the system is also becoming a more attractive target for hackers.

According to new research, the Apple system is more affected by aggressive adware, especially in the US. Ransomware also poses a serious threat to OS X as cybercriminals are increasingly targeting Apple users.

Most internet security vendors now offer a device-centric approach to security, including Mac OS protection as standard on their higher-priced suites. This means that if you own both a PC and Mac, you wouldn’t have to purchase two different security software programs and just by a Multi-Device Antivirus option.

AntiVirus vs Malware Protection

The term “anti-virus” can be confusing, seeing as viruses are not the only forms of malware out there, and one must make sure that software they are considering protects the computer against not just viruses, but also adware, spyware, worms, and other threats. In the 90s, viruses were most popular, and that is where the term “anti-virus” comes from. Yet they are a minority when all malware is taken into account. Trojans, Worms, Backdoors, Exploits, Adware, and PUP (Potentially Unwanted Programs) are more common than viruses, and these can include communication clients, remote desktops, password travelers, and more.

Malware affects your computer by slowing down its processing speed or showing pop-up windows frequently. But it can also do things like stealing your private data (credit card numbers or your bank account’s login data) that usually go unnoticed. As malware activity is not always noticeable, you should not assume that since your computer is working properly; it is free from malware as well. You need to install an antivirus program on your computer that runs in the background and identifies incoming threats effectively. Most of the software also runs regular scans to check all the computer files for any threats left undetected.
