#Worm virus portable#
The increased use of portable computers, e-mail, remote link-ups to servers, and growing links within networks and between networks mean that any computer that has a virus is increasingly likely to communicate with - and infect - other computers and servers than would have been true a few years ago.About 200 to 300 new viruses are being created each month, while the old ones continue to spread.
#Worm virus software#
The same technology that makes it easier to create legitimate software is also making it easier to create viruses, and virus construction kits are now available on the Internet.

"From an information security point of view, one of the more dangerous types of malicious logic is a Trojan Horse that allows a remote user to access and control your computer without your knowledge whenever you are on the Internet.

They are intended to cause serious damage such as deleting files, provide access for an outsider to copy your files, or disrupting the operation of an entire computer network or organization. "Of greatest concern, of course, are viruses and other devices that are deliberately malicious. They steal computer memory, storage, and processing time. For example, a virus may be designed to conceal itself until a predetermined date, then flash a message on all network computers. "Some viruses are high-tech pranks not intended to cause damage. It waits until triggered by some pre-set event or date and then delivers a payload that may include destroying files or disks. A Trojan Horse masquerades as a legitimate software program. A logic bomb is a program normally hidden deep in the main computer and set to activate at some point in the future, destroying data. A computer worm spreads like a virus but is an independent program rather than hidden inside another program. "Worms, logic bombs, and Trojan Horses are similar "infections" commonly grouped with computer viruses. A virus is only one of several types of "malicious logic" that can harm your computer or your entire network. Like a real virus, it can reproduce, infect other computers, and then lie dormant for months or years before it strikes.
#Worm virus code#
"A virus is a small, self-contained piece of computer code hidden within another computer program. By doing this, you can mitigate human failures that could jeopardize the entire company operation.Derived From: Viruses and other Infections, Dept of Energy It’s important that your employees understand the risks, know the threats and how they work. In addition, to finish, you need to work on security awareness within the company. Remember that many email attacks happen through phishing and spear phishing scams, often using social engineering tactics. So to enhance your protection and security it would still be important to use an email protection solution, such as a Secure Email Gateway. In the case of businesses, keep in mind that the vast majority of malware attacks occur by email. Threats like worms exploit flaws and vulnerabilities in software and products. In addition, handle suspicious files carefully, make frequent backups, and keep systems up-to-date. A good start to blocking and preventing infections from viruses, worms, and other malware is to adopt a good anti-malware solution and, in the case of a network, to have an efficient firewall.
