Yes, friends, of course, antivirus and other security software, the precaution of viruses and security threats that develop linearly with developing technology, so does the software we have taken really work, or is it just a popular name but it can’t do much in sight? In this article, we will try to answer your questions as much as possible. /strong>
A virus is a piece of computer code that can jump from computer to computer by attaching itself to a program or a file.. Infects new computers as you jump. Viruses can damage your software, hardware, and files.
Virus (i.) Code written for self-replication. A virus attaches itself to a carrier program and then tries to spread from computer to computer. It can damage hardware, software, or information.
Just as viruses that affect humans range from Ebola to the 24-hour flu, computer viruses range from the slightly annoying to the totally devastating.. The good thing is, a real virus doesn’t spread without human action.. Spreading the virus requires someone to share a file or send an email.

What is a worm?
A worm, like a virus, needs to copy itself from one computer to another. designed but does this automatically. First, it takes control of properties that transmit files or information on the computer.. Once the worm enters your system, it can progress on its own.. The greatest danger of worms is their ability to reproduce themselves in large numbers.. For example, a worm could send copies to everyone in your email address book, and then their computers could do the same.. Heavy network traffic brought by this domino effect can slow down business networks and the entire Internet.. New worms spread very quickly when they first appear.. They lock down networks and possibly cause you and others to wait long while viewing Web pages on the Internet.
Worm (i.) is a subclass of viruses. A worm usually spreads without user action and distributes exact copies of itself from (possibly modified) networks to networks. A worm can consume memory or network bandwidth, which can cause the computer to crash.
Since worms do not need a “carrier” program or file to spread, they can also tunnel through your system and allow someone else to remotely take control of your computer.. Examples of recent worms are the Sasser worm and the Blaster worm.

What is a Trojan horse?
How does the Trojan horse in mythology seem like a gift, but actually conquers the city of Troy? if he was carrying Greek soldiers to pass through; today’s Trojans are also computer programs that look like useful software, but they compromise your security and do a lot of harm.. A recent Trojan appeared as an email with attachments claiming to be Microsoft security updates, but the attached files turned out to be viruses aimed at disabling antivirus and firewall software.
Trojan horse (i.) A computer program that appears to be useful but actually does harm.
Trojan horses are spread by luring people to open a program they think comes from a legitimate source.. To better protect users, Microsoft sends security bulletins via email; but these are never supplemented. In addition, all of our security alerts are posted on our Security Website before they are emailed to our customers.
Trojans can also be found in software you download for free.. Never install software from an untrusted source. Always download Microsoft updates and patches from Microsoft Windows Update or Microsoft Office Update.

How do worms and other viruses spread?
Almost all viruses and Many worms cannot spread unless you open or run a program they infect.
Many of the most dangerous viruses spread primarily through email attachments (files sent in an email message).. You can usually tell if your email contains an attachment because it is shown to you by a paperclip icon representing the attachment and its name.. Photos, letters written in Microsoft Word, and even Excel spreadsheets are some of the types of files you might receive by email every day.. A virus takes action when you open an infected file attachment (you usually double-click the attachment icon to open an attachment).
Hint
Tip: The attachment of an email unless it is waiting for the attachment and knows the exact contents of the attached file. Do not open anything.
If you receive an email with an attachment from someone you do not know, delete it immediately. Unfortunately, sometimes it’s also not safe to open attachments from people you know.. Viruses and worms have the ability to steal information from e-mail programs and send themselves to anyone listed in the address book.. So, if you receive an e-mail from someone with a message you don’t understand or a file you didn’t expect, always contact that person and verify the contents of the attachment before opening the attachment.
Other viruses Programs you download from the Internet, infected can be spread through computer discs or programs you buy from a store. These are rare ways of contracting the virus.. Most people get viruses when they open and run unknown email attachments.

How can I detect if I have a worm or other virus on my computer?
When you open and run an infected program , you may not realize you have a virus. Your computer may slow down or crash and restart every few minutes. Sometimes a virus attacks the files needed to start the computer.. In this case, you may see a blank screen when you press the power button.
All these symptoms are common signs that your computer has a virus; however, sometimes it can be caused by hardware or software problems that have nothing to do with the virus.
Watch out for messages that you’ve sent an email containing a virus. This could mean that the virus is showing your email address as the sender of the email it created.. It does not mean that your computer has a virus. Some viruses have the ability to generate fake email addresses.
Unless you have up-to-date antivirus software on your computer, there is no reliable way to tell if you are infected with a virus.. If you don’t have up-to-date antivirus software or want to install antivirus software from a different manufacturer, visit our Security software downloads page.

Next steps: Reducing virus risk
None something cannot 100% guarantee the security of your computer. However, you can continue to improve the security of your computer by keeping your software up-to-date and getting an up-to-date antivirus software subscription. >
Virus writers in this category can be said to be a community of oppressed intelligent people, but it can also be said that they are an option to make their voices heard and get rid of oppression, either because they do not get enough for their efforts or because they cannot really find another way to release their personally suppressed emotions.
The same thing can be said. hackers do it by crashing websites.
2- Commercial Purpose I do it first, then I clean it up. Writing Viruses for Exploitative Purpose
I have that much knowledge and why should I misuse this knowledge? I mean, let’s summarize a few lines from the dictionary. As it is known, we can say that the back side of these antivirus companies, that is, the work of the top secret units of money laundering established by many companies in trade that we do not know.. It is a known fact that all antivirus companies first make the virus and then clean it, unless people know how to create such a sector, first the necessary environment is created and then the supply and demand balances are created.
Well, after all this explanation, let’s get back to our real business Here is the test made by us.
We are here with the test of cnet editors as a result of their research. While the guys couldn’t even enter the lists in 2006, they are now among the best. Although Mcaffe incorporated a firewall in 2007, it also achieved very good results, not to mention the failed nod32. BitDefender-10 is like a ball passes through the firewall, but its performance in cleanups finally, trend micro is always trying to prevent viruses. It impresses with its performance at the top of lists like i and its success in neutralizing the pest.
