Worm-this type of virus is able to spread itself automatically over the network from one computer to the next.During a worm attack,users'computers get infected without even having to click open email attachment or any program,etc. Since it is very difficult to avoid the virus,your best defense is a powerful antivirus program.In order to fight with such viruses,the software vendors should focus on making their products more robust.This may ask for a trade-off between user-friendliness and security.In specific cases it may require line-by-line inspection,code retooling and even systems automation to defend the installed programs.
