 Top 10 most dangerous computer viruses 

In the list of top 10 most dangerous computer virus, I will be showing you the cost, date, reach and other key facts.

Please take a note of that I will be using virus and worms interchangeably as people search for that type of word that's why but there is a difference between will be explaining you after this post so let's begin:-

1. Mydoom-$38 billion

Mydoom Virus

The most was computer virus which outbreak in the history is the Mydoom caused estimated damage of $38 billion in the year 2004, but its inflation adjusted cost is $52.2 billion, it's also known as Novarg, this malware is technical a "worm", which was spread by mass emailing at one point, this my dream virus was responsible for 25% of all emails sent.

Mydoom is such a virus that is crap adress from the infected machine and then send back copies of itself to those addresses it also roped those infected machine into web of computer called a botnet that performs is distributed denial of service attack (DDoS). Is attacks is mainly used for shutdown the target website for this servers.

Mydoom is still around today, generating 1% of all phishing emails. That’s not a small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation.

Though there's $250,000 was offered to the developer who has made this most dangerous computer virus was never caught.

2. Sobig- $30 billion

Sobig Virus

In 2003 Sobig the computer virus was actually an another worm. It was the  second only to the Mydoom virus in its scope. About $30 billion figure was a worldwide total amount, including the country like Canada, U.K., U.S., mainland Europe, and Asia. There are several versions of the worms were released in very quick succession, which was named as Sobig. A through Sobig.F, with Sobig.F was the most damaging one.

In this cybercriminals program masqueraded as legitimate computer software were attached to the emails. It has disrupted the ticketing process at Air Canada and interfered with countless other businesses in the world. Despite of its widespread damage, the creator of the successful bug was never been caught.

3. Klez- $19.8 billion

Klez Virus

The Klez was a very close third on this list of the worst computer viruses ever created in this world. With nearly $20 billion in estimated damages, it has  infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm has sent many fake emails, spoofed by recognized senders and, among other things, were attempted to deactivate all other viruses.

As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last.

Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU- $15 billion

ILOVEYOU Virus

In the year 2000’s ILOVEYOU virus has worked only by sending a msg “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent the  copies of itself to every email address in the infected machine’s in their contact list. Shortly after some of its May 4 release, it had spread out to more than 10 million PCs.

The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter.
