ANTIVIRUS: MEANING AND THE BEST AND THE WORST

What is an antivirus?

It seems pretty simple and easy to tell what an antivirus is. Who has not yet heard of this type of software, its importance, and why it must always be updated? Here you will find a lot of information related to antivirus, to help you better understand this type of software and how they work.

Antivirus is a program that helps in protecting your computer against most viruses, worms, Trojans, and other unwanted invaders that can infect your computer.

Antivirus- Meaning and the best and the worst
Among the main damages that these programs can cause are:

·       The loss of microprocessor performance,

·       Deletion of files,

·       Data alteration,

·       Confidential information exposed to unauthorized persons, and

·       The uninstallation of the operating system.

Over the years, viruses, malware and other threats that threaten us every time we access the Internet or connect an unknown pen drive to our computer, have progressed to a level where they are practically undetectable. Also the ways in which they are introduced into our computers is increasingly sophisticated and treacherous.

Hardly a user who uses the Windows operating system, any of its versions, has not used any antivirus software on his computer, at least once in his life. We are not saying that only Windows is conducive to malware, but because it is the most widely used operating system in the world, it is the target of choice for creators of digital pests. This is because crackers always try to reach as many users as possible.

Normally, antiviruses monitor virus activities in real time and make periodic checks.

Today's antiviruses have specific vaccines for tens of thousands of known virtual pests, and thanks to the way they monitor the system, they can detect and eliminate viruses, worms and Trojans before they infect the system.

Antivirus must be updated frequently, as with so many malicious code being discovered every day, products can quickly become obsolete. Some antivirus can be configured to update automatically. In this case, it is advisable that this option is enabled.

Techniques of virus detection

The main objective of the antivirus is to detect and remove malware programs from your computer. Since the first step is to detect, there are some techniques for that.

Detection techniques include:

- Signature Verification

- Heuristic Verification

- Behavior Blocking

Differences between the best and worst antivirus

Here we have are going to discuss about the difference between the best and the worst antivirus, what they do, what they can’t etc. etc.

- Malware detection time and vaccine distribution: It is important that the antivirus provider be quick in detecting new malware and especially in the distribution of vaccines.

- Frequency of update of the definition list: The definition list should be updated often. Every day many malware appear on the net. If the definition list is not updated often, there is a great possibility that we will end up infected.

- Scan time: Scan time is another important factor.  Reading the files should be fast. A slow scan is always problematic, as the machine finds itself with a process running and absorbing a large part of its resources.

The best scan is the one that is not noticed. The antivirus performs the reading of the hard disk of the PC and you do not even know what it is doing.

- Amount of malware identified: The best antivirus are those that manage to detect as many malware as possible. Normally in antivirus tests, this number is the big differential.

- Number of false positives identified: Here, the less the better. An antivirus that detects files without viruses and considers them malware is a big headache. Mainly if you are going to remove a healthy file and make an application or even the operating system stop working.

- Price: The item price must be considered. We have nothing against free antivirus, but if there is a paid version, we agree that this version will be more efficient than the free one. The prices of the antivirus are so cheap, that it is worth the investment.

Conclusion

Antivirus is one of the most important thing that should be installed in your device to fight against all the odds and uneven events. Go for the best antivirus software that fulfill all your requirements and can protect you from all the new and old viruses, malware, and worms.

What Is the WeAreDevs Virus?

This is another case of a purported virus that truly doesn't fit the definition of most computer viruses. It's not by any means malware, really. In any case, despite everything can be hazardous: While downloading a hack from that website, you could have effortlessly downloaded an adventure, too. Adventures are known tools of cybercriminals intended to exploit any security shortcomings on your computer. Since the endeavour could have been downloaded from the WeAreDevs webpage, it is known as the WeAreDevs virus when it tends to be followed back to that website. How Does the WeAreDevs Virus Work? Once installed on your computer, an endeavour helps genuine viruses and malware infiltrate your system. It's only a little bit of software or bit of code however it fundamentally powers open any holes on your system and lets malware effectively go through. Endeavours normally work by allowing the malware to divert you to a compromised website with imperceptible presentation pag...

WHAT IS BOTNET ATTACK?

Image
The number of cyber-attacks has grown dramatically in recent years. Hackers are targeting governments, businesses, and individuals around the world, and you may have unwittingly assisted them in carrying out their attacks. If you have ever clicked on a link in a suspicious email and similar emails have been automatically sent to all your contacts, you have surely been a victim, and an accomplice of a botnet. The definition: It is a word made up of the words "robot" and "network". A botnet is a group of computers remotely controlled and coordinated to carry out harmful tasks. A single botnet can be made up of between several hundred and several million computers, they are called “bots” (the word “robots” shortened). Botnets can access your computer through the installation of malicious programs, a direct attack by a hacker, or an automated program that scans the internet for security deficiencies (for example, lack of virus protection) that can be exploited. .

Original or Pirated Virus Protection Which Is Better

Image
The use of shields in computer systems has been used since IBM suffered the Creeper attack in 1972. To try to stop this, Reaper was developed in 1973. This is not virus protection like those of today, since they have evolved a lot. Despite their useful feature, many users choose not to pay for them and get pirated versions. So Genuine or Pirated virus protection, which is better? Also, updates to the system will not run on the illegally acquired version. That means: Stein would have to continue to load software from dubious providers - with the risk that viruses or Trojans are hidden here that search the computer for passwords for online banking, for example, and send them to the author. In a study, market observers from IDC found that a few years ago, websites that offer cracked software had spread 25 percent of malware such as Trojans at the same time. In the case of file-sharing networks, it was almost 60 percent. It often takes less than a day after a game is rel...
