To remove a computer worm, simply run a malware scan with an antivirus software. Once the worm has been detected and removed, your computer should be completely safe to use. While you can prevent it by following the methods in the post.

The main difference between a computer virus and a worm is that while a virus needs a host - most often an executable (although there are viruses written in scripting languages ​​that adhere to a document or spreadsheet) that modifies itself by appending code to it executable, the worm is independent in this regard and spreads across all networks connected to the infected computer, taking advantage of operating system vulnerabilities or the user's naivety. In addition to replication, the worm can also perform additional functions such as destroying files, sending mail (usually spam ), or acting as a backdoor or Trojan horse.

There is no better way to identify, remove, and prevent computer worms than by using an antivirus program and a computer worm removal tool.

Computer Worm Examples
What is a worm virus? The above section has given you much information about it, this part we have listed several computer worm examples for you.

Morris Worm

The Morris Worm was found in November 1988, which was created by and named after Robert Morris. It was the first computer worm, and it disrupted nearly 10% of computers on the Internet.

Stuxnet Worm

The Stuxnet worm was found in June 2010, which was created by the United States and Israel. The Stuxnet virus targeted Iran's Uranium Enrichment Program.

Stuxnet was created as part of a top-secret cyberwar plan for the “Olympic Games”. Between 2008 and 2012, this computer worm caused 984 centrifuges to crash at Iran’s nuclear power plants, shrinking Iran’s nuclear weapons production capacity by about two years.

Duqu Worm

The Duqu computer worm was found in September 2011 and is believed to be related to the Stuxnet worm. Duqu was created by the government to steal information about Iran’s nuclear production. Some versions of Duqu did contain a payload that can delete files from the host computer.

Flame Worm

The Flame worm was discovered in 2012 and is considered to be one of the most complex computer worms discovered to date. Flame’s code has many similarities with Stuxnet's code, but Flame was created purely for cyber spying. Since its deployment, Flame has infected thousands of computers, most of them in Iran and other Middle Eastern countries.
