How to Protect Computer from Virus And Ransomware & Wannacry Virus That Crippled the NHS

What is Computer Virus 

A computer virus is a type of malicious software program (“malware”) that, when executed, replicates by reproducing itself (copying its own source code) or infecting other computer programs by modifying them. Infecting computer programs can include as well, data files, or the “boot” sector of the hard drive

Computer Virus Attack in Ireland

The Government Of Ireland says it has not received any reports of any incidence of attacks in Ireland involving a new form of computer virus which is sweeping the globe.

Taoiseach Enda Kenny has said that the issue is a very serious matter and is being monitored on an hourly basis.

How does a computer virus attack?

Once a virus has successfully attached to a program, file, or document, the virus will lie dormant until circumstances cause the computer or device to execute its code. In order for a virus to infect your computer, you have to run the infected program, which in turn causes the virus code to be executed. This means that a virus can remain dormant on your computer, without showing major sings or symptoms. However, once the virus infects your computer, the virus can infect other computers on the same network. Stealing passwords or data, logging keystrokes, corrupting files, spamming your email contacts, and even taking over your machine are just some of the devastating and irritating things a virus can do.computer Virus Attacks in software data so be carefully to click on any fake mails and websites

The following Above Steps that protect our computer from virus

What is ransomware?

Ransomware is a type of malicious software that criminals use to attack computer systems.

Hackers often demand the victim to pay ransom money to access their files or remove harmful programmes.

The aggressive attacks dupe users into clicking on a fake link – whether it’s in an email or on a fake website, causing an infection to corrupt the computer.

In some instances, adverts for pornographic website will repeatedly appear on your screen, while in others, a pop-up will state that a piece of your data will be destroyed if you don’t pay.

In the case of the NHS attack, the ransomware used was called Wanna Decryptor or ‘WannaCry’ Virus.

Ransomware attacks spread ‘world wide’

Ransomware is a kind of cyber attack that involves hackers taking control of a computer system and blocking access to it until a ransom is paid.

A ransomware virus is spreading aggressively around the globe, with over 100,000 computers in 99 countries having been targeted, according to the latest data. The virus infects computer files and then demands bitcoins to unblock them. Ransomware hackers may be using a US National Security Agency cyber weapon

Earlier today a massive ransomware virus attack spread to the computer systems of hundreds of private companies and public organisations across the globe.

The software locks computers and asks for a digital ransom before control is safely returned.

Ransomware attacks are not new, but the speed of the recent hackings has alarmed security experts.

What is the WannaCry virus?

The WannaCry virus targets Microsoft’s widely used Windows operating system.

The virus encrypts certain files on the computer and then blackmails the user for money in exchange for the access to the files.

It leaves the user with only two files: Instructions on what to do next and the Wanna Decryptor program itself.

The world has become so dependent upon machines in order to function. It’s a frightening thought that everything including national security healthcare and banking are vulnerable. While some court’s will protect the privacy of some who are under suspicion of cyber crime they are putting the rest of us at risk. Don’t overlook that the nuclear button is computer activated.so be carefully for any fake mails and wrong messages.

This one is quite simple – there’s no guarantee that victims will get their data back even if they caught up cash cyber crooks demand from them. Plus there is no guarantee that the attackers won’t strike you again or demand more.Now a days the main problems our computer system and secure data will loss to unknown hackers.
