How t get rid of a link virus. Immediately open task manager and look for a suspicious name. Then end the process. Then read windows key and r to get run and type in %appdata%. Look in windows and you should find it. Only do the appdata part if task manager didn’t work

How about NIMDA and BLASTER ? They had worst consequences and were more widespread ! Nimda destroyed more MS Servers than any of those cited in the video while Blaster, also known as LOVESAN is one of the most virulent viruses ever seen and rendered your PC useless. Also, if you left 1 PC infected on your site, most PC got then reinfecteed within a few minutes of the infected PC being turned on or plugged into the network again. It took also very long for MS to get a patch out to correct the vulnerability and then it took ages to patch machines. You could still find PC infected with the original or onr of the variants even as late as 2006, three years after the original infection.

Just to explain that part at the end : Computers are NOT smart, as you already know they only understand 1's and 0's and that gets changed to whats known as code, and when you type a line of code for example : printf("Hello, world") that means you are telling the computer : "Hey computer, please print on my screen (Hello, World)" and computers will always need instructions to follow or else it would stop, and also to convert code into "Binary" the computer uses a compiler which ALSO uses code and if you think computers are smart NO, you are wrong! Because computers as i said need instructions to follow or they will just stay there looking like a decoration but what the computer does on the inside though with CPU and bla bla bla... it also uses code to let the computer know which transistors to turn on or off and bla bla bla... also for the pixels too and they are pretty dumb machines so you have a line of code for it to follow and TADA! you got a program! Some more 1's and 0's you get an operating system but yeah they still follow certain code lines and that is basicly it, anymore explanation?
