What are the possible ways a computer can contract a virius?

sneakernet, local net, internet... whatever.\n\nAny path that data is able to reach your computer, so is a virus.

It almost sounds as if your project is going to eventually become a "virtual machine", or better yet a simulated computer.\n\nThe first step is to determine your instruction set.  The computer will probably have the ability to perform simple arithmetic, such as add, subtract, multiply, divide, shift, jump to memory locations, etc.  Each of these operations will use a unique sequence of 'bits' to identify the specific operation.  For example, you can say that your machine only supports only sixteen instructions.  Because it is sixteen, we can identify each instructions with four bits:\n\nMOV   0000 - move data\nADD   0001 - add data\nSUB   0010 - subtract data\nMPY   0011 - multiply data\nDIV   0100 - divide data\nAND   0101 - bitwise 'and'\nOR    0110 - bitwise 'or'\nXOR   0111 - bitwise 'exclusive or'\nNOT   1000 - invert bits\nJMP   1001 - unconditional jump\nCMP   1010 - compare values\nJEQ   1011 - jump if equal\nJL    1100 - jump if less than\nJG    1101 - jump if greater than\nJLE   1110 - jump if less or equal\nJGE   1111 - jump if greater or equal\n\nOnce you determine the instructions the computer will support, you need to determine your addressing modes.  For example, an "add" instruction can work with two registers, two memory addresses, a memory address and a register, or indirect combinations of both.  For each addressing mode, we will assign a sequence of bits.  I'm going to choose only four addressing modes, "immediate" (where the data in the instruction is taken as a literal value), "memory" (where the data in the instruction is a memory address), "register" (where the data in the instruction is a register number) and "indirect" (where the value in a register is a memory address to where the data points).  I will use two bits to identify the source addressing mode, an another two bits to identify the destination addressing mode.  If the instruction only uses one destination, the second two bits would be used.  This is now a total of four bits which we combine with the first four bits of the opcode.  Below are the bits we will use for the modes:\n\nImmediate - 00\nRegister - 01\nMemory - 10\nIndirect Register - 11\n\nNow, we have defined a fairly competent instruction set that identifies the operations and addressing modes with only one byte of data!\n\nJust to show "mnemonics" of the assembly language of our computer, with addressing modes, consider the following:\n\nADD 10, R2 - Add number 10 to register 2 (immediate/register)\n\nADD R1, R2  - Add register 1 to register 2 (register/register)\n\nADD @MEM1, R2 - Add value in memory at MEM1 to register 2 (memory/register)\n\nADD *R1, R2 - Add value pointed to by address in register 1 to register 2 (indirect/register)\n\nNow, they would equate, in bits to the following:\nADD 10, R2      0001 00 01  (11 in hexadecimal)\nADD R1, R2      0001 01 01  (15 in hexadecimal)\nADD @MEM1, R2   0001 10 01  (19 in hexadecimal)\nADD *R1, R2     0001 11 01  (1D in hexadecimal)\n\nNote that each instruction and addressing mode is one byte, but only part of the complete instruction.  You can use the bitwise and (&) operator in C++ in order to mask off the opcode and addressing modes from that single byte (unsigned char).  So:\n\nopcode = byte & 0xF0;       (1111 0000)\nsourcemode = byte & 0xC0;   (0000 1100)\ndestmode = byte & 0x03;     (0000 0011)\n\nOnce we've determine the addressing mode for each one, the next sequence of bytes after the opcode and mode would be either the immediate value, a register value or a memory address.  The remainder of each instruction can be either a fixed or variable number of bytes, that is your choice.\n\nFrom there, you just process a stream of bytes and you can get the extract the operation, addressing mode, data for source and destination (or just destination if its a single operand).  Next, your "virtual machine" needs to sim

What you are asking for is a way to set up dumb terminals hanging off of an XP box.  Not saying it couldn't be done, but the cost would be higher than simply buying the right stuff to do it to begin with.  \n\nTerminal services on a windows server will do this, but you would still have to have a workstation for each user to connect to the server with.  If you are trying to avoid having to purchse the CPU, go buy an e machine.  You can get the whole thing for $400 or less.

I think what you're looking for is something like "Black Viper's Services Configuration". I'll add a link. Good reading. :)

The fact is ... you can't. You'll may free the system of viruses, but it won't last longer. An expert might help you, though.\nBut why are you using Windows as a server platform? It COSTS money, it's not reliable and you'll always have problems with viruses, trojans, adware, junk, spyware and all kinds of scam.\n\nYou can minimize the impact by using a good firewall, a good antispyware program and a good anivirus. Do not use the firewall bundled with some new versions of Windows, it sucks - bloks what shouldn't be blocked and allowes what shouldn't be allowed. Try Kerio or Zone Alarm. Use Ad-aware Proffesional as an antispyware program and NOD32 as an antivirus. These programs may be commercial. Note that these are the programs that best suited my PC, so there is no guarantee that they should work perfectly on your computer. Update these programs daily and periodically run full system scans in search of viruses and scams. And ditch Internet Explorer browser, use Mozilla Firefox, Netscape or Opera instead - they are all free. \n\nBefore switching to programs such as the ones I recommended you, reinstall the operating system, and if possible, format all your hard drives / partitions. This way you are sure that you are free of scams. Of course, don't forget to back up all your important files to some removable media or such.\n\n\nFinally, I warmly recommend you to use a Linux distribution (there are thousands available, for FREE) - if you're in doubt, http://www.linux.org might help you in finding the Linux that best suits your needs - or FreeBSD (can be downloaded for free from http://www.freebsd.org/ ). These operating systems are almost immune to Windows scams, are reliable, FREE, and with a big community behind each one, redy to help you each time you have problems.\n\nHope this information will help you. If you're stiil in doubt or if the answer didn't solve your problem, feel free to IM me.\n\nNote: google helps a lot in finding the programs you want. http://www.google.com

Probably nothing that you don't already have. Just about any computer these days can function as a server. What exactly are you trying to do? Please let me know and I'll provide more specific info.

It's part of an antivirus system. Check the vendor's web site.

no im sorry but theres not. while its true that the two are the same basic thing, the interface is completely different. so its possible maybe if your a computer technician to jerry rig something...but if so you would have done so already instead of asking us.sorry.

such a vag thing so many problems!  you can try all sorts of things.  alot of software is out to debug a computer like norton windoctor etc, could be a virus, could be spyware my good ness could be nearly anything.  Best way if you don't know alot about computers is simply to backup and format then if it crashes you know its hardware.

...nice. that could be fun!\nIt depends on which operating system you (and the other computer) is running. In linux and Windows (maybe Mac?), IF the client computer is running some sort of VNC host in the background(the computers @ my school do), you might be able to log into the client using the VNC and open a sound file, or execute a script to open a sound. You would need to put the VNC client/controller software on a thumb-drive or CD. Questions or comments? E-mail cdax16@yahoo.com
