| comp., MS | virus de programa | program infector virus (A virus that attaches itself to executable programs. Once the original infected program is run the virus transfers to the computer memory and may replicate itself further, spreading the infection. This type of virus can be spread beyond one's system as soon as the infected file or program is passed to another computer. The simplest form of these viruses work by overwriting part of the program they are infecting. More sophisticated versions hide their presence by saving the program or file's original instructions so that these are executed even after infection) |
