what is the opposite for the virus? and what is the charactiristic of that?


i was confusing what is the difference between virus and the vice versa of the virus? And can any body here give me a code to study between the virus and the yang of the virus (yin-yang)

The question of the "opposite" of a computer virus has already drawn several useful but different replies in this thread. started the discussion, framed the answer around propagation, suggested a self‑removing program, and applied the clinical "vaccine" analogy. All are valid — the right opposite depends on which property is being inverted (how it spreads, what it does, or who/what fights it).

Three practical ways to look at "opposite":

  • Functional opposite — software that intentionally does not self‑propagate and is transparent about its behavior (regular, consented installations and services).
  • Intent opposite — a self‑replicator with a beneficial purpose (a controversial concept sometimes called a benevolent or remediation worm; it exists in theory but carries serious ethical and legal issues).
  • Defensive opposite — an anti‑malware or "vaccine" program that detects, isolates and removes malicious copies; this matches and ’s points and is how defenders usually think about reversal.

Detection and remediation are complementary: defenders rely on signatures, heuristics and behavior monitoring to spot the symptoms noted earlier in the thread, then quarantine, roll back or remove the malicious components. Trustworthy software follows the opposite pattern: minimal privileges, clear install paths, code signing and no hidden propagation.

Safe, practical next steps for anyone wanting to study these differences (without creating or spreading malware):

  • define which "opposite" is of interest (functional, intent or defensive);
  • use an isolated lab (virtual machines with snapshots, host‑only networking and no shared folders);
  • work only with curated, legal samples or intentionally benign exercises; use static inspection and monitored dynamic analysis (process-level monitoring, autorun inspection, network capture) inside the lab;
  • keep legal/ethical constraints in mind and never run unknown binaries on production systems.

In short: there is no single opposite — choose the perspective, follow safe lab practices, and build understanding of taxonomy, detection and remediation rather than pursuing live propagation code.

>what is the opposite for the virus?
What is a virus? It's basically a program that propagates itself, "infecting" the target computer. The opposite of a virus would be any program that doesn't multiply on its own at all.

You might also define a virus as a self-multiplying program that has a malicious payload[1]. In that case the yang to a virus' yin would be a self-multiplying program that has a beneficial payload. In this case it wouldn't be the defining characteristic of a virus that specifies an opposite, but the intention in which the program is written.

[1] I wouldn't, but you might.

I wouldn't say that malicious payload is a requirement for a virus. So I would just say that the opposite to a virus would be a program that tried to remove all copies of itself

Virus definition:

They replicate quickly
Viruses "phone home"
Viruses use up system resources - making your system slow and causing the user to think they need new hardware
Viruses may trash your hard disk
Viruses can lead to system instability
Often installed without the users permission
Viruses may take your money

Does that make ms windows a virus ? ;)

>>Viruses may trash your hard disk
Oh yes -- what was a feature built into MS-DOS 6.X and Windows 95. I can't count the number of times I had to reformat the hard drive and reinstall everything from scratch.

I have not had that problem since Windows 2000.

my nt4 server system has been running for ~4 years without crash.

NT based is far > DOS based

i want to know whats is the opposite of the virus

Opposite how?

A regular program works as advertised, a virus doesn't.

A regular program is open about it's functionality, a virus isn't.

A regular program doesn't cause damage (usually anyway), a virus usually does. The damage can take many forms, from the machine running a bit slow to complete loss of data, or maybe even data theft.

A regular program is usually installed with full user knowledge, a virus infects automatically or via "social engineering" of the victim (eg, email saying "play this fun game").
Additionally, a virus also has the means to propagate itself.

Clinically speaking, the opposite of a virus is a vaccine. So a vaccine program is one which goes round killing off virus programs.

Does that make ms windows a virus ? ;)

MS Windows isn't a virus. A virus does something.

i get it the opposite of the virus is a helpfull program like MS windows and microsoft office.

and the example of this virus is trojan virus>? am i right can i ask what are the types of virus and its characterstics.?

trojan
worm

etc...

trojan worm and what is that etc.... and their characterissssticc

what do you call to the virus that comes from flash disk

"get Outa Here, Now!" ;)

what do you call to the virus that comes from flash disk

a virus ;)

"get Outa Here, Now!" ;)

and Y?

Virus :)

i know dat is virus but wat kind of virus?

depends

ok and im ocnfusing Y many of our co-programmer create a anti-virus and they app. has different types of virus?

and Y?

I'd not want that virus there so I'd tell it to get moving ;)

what?


Y they create a virus?

"get Outa Here, Now!"

:)

Y they create a virus?

All sorts of reasons. Maybe they want to have your adressbook, maybe your creditcard numbers or maybe they're just doing it for the kick.
Asking why people make virussses is the same thing as asking why hooligans exist

Niek

ow i get it and y many of our co-developer create a
anti-virus but their program has different types of virus that was deleted?

i think using up to date antivirus is the best way to get rid from viruses

?.? what?

hello can any one know how to put a program to start up using a notepad only...?

Um, don't waste your time. If you want to write machine code, use a hex editor so that you can have direct control over the binary contents of the file. You'll want to learn about the PE (portable executable) file format that Windows uses, and the x86 instruction set. Then you can use the hex editor to manually write your own PE.
