What is the major difference between worms, virus, malware and Trojans? Which is the most dreaded? What security and personal strategy are best in fighting viruses, Trojans and worms? Can a system be infected without access to external networks (For example Internet)? What measure should be used in case of infection?
Major differences of different types of malwares are the style of damaging the system of our computers. They differ on how our computer will react once they are present in our computer system. They all could cause a real harm on our system if not eliminated. The best strategy is to install anti-virus and regularly updating. Computers may still be infected once a not so clean external disk or USB is used. In cases that there is already a sign or your anti-virus has already detected a malware present in the system, run immediately your anti-virus or rather activate your anti-virus.
Hi Lloyd!
The Trojan virus can actually do big damage once installed or run on your computer. People get infected with it by being tricked to open files or software from a legitimate source, that they receive. The results of a Trojan when activated on your computer can be different kind: some Trojans can change your desktop, add desktop icons or they can cause major damage by deleting files and destroying information on your system. Unlike viruses and worms, they do not reproduce themselves by infecting other files. Trojans can also compromise your personal information.
Worms spreads from one computer to another, but unlike a virus, it has the power to travel incognito. What it mainly takes advantage of is file or information transport features on your system, which is what allows it to travel un-noticed.The biggest danger with a worm is that it replicates itself on your system, so instead that your computer sends out a single worm, it could send out hundreds of copies of itself, creating a huge devastating effect like for instance, a worm sends a copy of itself to everyone in your email address book and then, the worm multiplies and sends itself out to everyone listed in each of the receiver's address book and so on. Huge danger at the most cases is that the worm takes out too much system memory or network bandwidth, which is causing Network and Web servers as well as private computers to stop working.
