View Full Version : Viruses, and such.

May 19th, 2010, 5:00 AM
Can anyone give me a list of, possible all, viruses and what they do? We haven't been learning about viruses yet and the only viruses I know are: malwares, Trojan horse, and worms.

Thanks to anyone who helps. :DDD

Asking for a list of all viruses would probably take 500 pages :( but there are spyware and adware as well

May 19th, 2010, 5:50 AM
May I ask what is the point of viruses in the first place? Why do people make them and send them to people? Is it only because they think it's cool?

May 19th, 2010, 6:00 AM
They just have nothing better to do and want to exploit stuff

Well, there's..
E-mail worms. (invade your email, and when you click on it, it'll give you a virus)
E-mail postcard viruses. (an ad or such that does basically the same as a worm)
Trojans (I have no idea, but i'm guessing they're bad viruses that come from tracking cookies)
Tracking cookies (track your computer. stalkers!)
Adware (ads that are unsafe and cause viruses)
Spyware (Tracking viruses that sick people use to track your computer... I think)
Malware (virus..)
Unsafe files (given to you by unsafe links to websites, and if saved to the hard drive they must be removed. [UNSAFE files] such as a picture gotten from an infected website)

that's all I know.
if you're having problems and asking that question, I suggest the best anti-malware system are the ones that DO NOT pop up at you while you're minding your own business.

oh, those are called malware I think.
they infect your computer by running a fake scan, putting on an act and telling you your computer is infected. DO NOT CLICK ON THESE. RESTART THE COMPUTER.
if you can't turn it off, then go immediately to internet, search FREE SUPERANTISPYWARE and DOWNLOAD it. run a scan. quarrantine the spyware and reboot and let the viruses BEGONE!

I can think of several reasons people make viruses.

Adware = self explanatory. They want to spam you with ads.

Computer destroyers = Idiots have the power to create these and do so. It's that simple, really.

Controlling viruses = These are the most deadly because they're meant to be impossible to get rid of. They're made by e-warriors who want power over other people, or less commonly idiots.

Spyware = self explanatory. They want to steal info they can sell / use against you.

There are only 3 real different types of malware.
Adware: Not a virus. Can however be dangerous to remove. Tries to push ads on victim
Virus: Intended to cause harm to the computer. The largest cateogry by far. The different kinds of viruses merely describe the method of infiltrating the computer or what it attacks.
Spyware: Not a virus. Can however be dangerous to remove. Tries to steal info from the victim's computer.

Haha, you got at what I was trying to say about that, Yellow. ^^;

well, I just remebered one more..
I dunno what's it's called but..

it can get into the hard drive through an e-mail (I think it's a computer destroyer)
erase all files, DESTROY the hard drive X (whatever it's called) and crash your computer within about five minutes or less.


and with the bad virus luck I have had...

I DON'T want this one after I got the LAST one on the NEWS!

So called "computer-destroyers" are most frequently "worms".

For databases of known viruses, it seems F-Secure has one that seems quite comprehensive.

Do you guys honestly think that the Antivirus companies aren't responsible for a large chunk of viruses?

*pokes head into topic*
Never really thought of that before; given that there are millions of idiots on the internet who want to make people's lives worse than they already are, I don't think so. Besides, that'd mean more work for them.

Thing is, there's a lot of illegitimate money to be made by making spambots that will advertise sites. One of the most lucrative forms of cyber-crime in the world.

Since I'm toying with some cracking and malware methods myself for the purposes of securing my own networks, I'll try and summarize how malware tends to work.

The purpose of malware is to deploy a given payload on a system. The payload can include anything from a harmless popup of kittens with the caption "you've been hacked" to a keylogger (records everything you type) to advertisements to remote access to your computer. Basically, anything goes.

There are a few different ways you can get hacked, but I'll focus on malware, since you probably don't run a website (webmasters have a big target on their back that says "hack me"). Basically, the malware author designs a malicious program and tries to get your computer to run it somehow. Once it does, it'll unleash whatever payload the author put into it, provided it isn't stopped by an antivirus. There are quite a few ways malware authors can get you to run their malware. The most common is to trick you into running it yourself.

For instance, the malware author may craft an email that looks like it comes from a reliable source, instructing you to open an attached file, which, as it turns out, is the malware. That's just an example, though. It certainly isn't limited to email. Many tools that claim to assist in software piracy may be malware; some even perform their function in addition to delivering their payload. It's actually quite simple; all the malware author has to do is get you to run a program. There are countless ways he could get you to do this; the practice of tricking people into doing this sort of thing is called "social engineering," and you can read more about it on Wikipedia (http://en.wikipedia.org/wiki/Social_engineering_(security)).

There are other ways to get you to run a program that don't require your interaction, however. These usually rely on exploiting some behavior in the software you are using. For instance, let's say the malware author has also managed to gain control of a website you like to visit. He might leave most of the website intact, but insert some code that takes advantage of a glitch in your web browser to run his malware.

Another potential avenue of attack could be at the operating system level. A lot of operating systems have services running in the background that connect to the internet for various reasons. Some of these services can be exploited to run malicious code and deliver a payload.

The best thing to do is to keep an antivirus program like Microsoft Security Essentials (http://www.microsoft.com/security_essentials/) running at all times and, if you are not behind a router with a built-in firewall (most routers have one), to also keep a software firewall running, such as Comodo Firewall (http://personalfirewall.comodo.com/free-download.html) (note that this comes with an optional antivirus that you should not install if you are using Microsoft Security Essentials). However, no software is an alternative to safe browsing habits; be sure not to run programs that you didn't seek out yourself and not to follow links to sites that deal with your personal information (find out the site's address and enter it manually each time; e.g., type 53.com into your URL instead of following a link from your email).

Also, know that there is no 100% safe solution (this is important). It is almost impossible to keep a determined cracker out of your system; there are ways to trick antiviruses and defeat firewalls, but they take time and effort that most common malware authors won't bother with (though someone determined to break into your specific system might). By knowing what you're doing, you can be safe from 99.9% of attacks, as most target people that don't know what they're doing.

I got one not long ago.

Luckily, it wasnt dangerous, or after password info or anything. I found it on my scanner, but before i could get rid of it it kept opening fake Antivirus Windows until my comps usage was up to 100%.

Then after about an hour, it stopped, and the scanner couldnt find it. It was like it obliterated itself.

I think the use of virus is to get money and other people's important information. For example: someone get paid to ruin the a company website like Microsoft and if it is successful and make the website down for 3 days, this could effect the company a lot and even lost a lot of money.

* Adware
Adware (or spyware) is a small program that is designed to show advertisements (in various form and degrees of intrusiveness) on your computer. It often reports personal information back to its owners. As a result your sense of privacy can be violated.

* Backdoor
A backdoor is a small malicious program that is used to gain access to a computer by bypassing the computer access security mechanisms. It gives the attacker almost unlimited rights. While it can be used to spy on a user, it is mainly used to install other malware on the system.

* Malware
A generic name for all types of malicious programs: adware, backdoors, rogues, trojans, viruses and worms.

* Rogue
A rogue program is a malicious program that is disguised, for instance, as trustworthy anti-spyware programs or registry cleaners. But these programs are only put on the market to scare you into buying these programs because they make exaggerated claims about the safety of your computer or, worse still, give erroneous scan results or put their own malware in your system.

* Trojan
A trojan (or Trojan horse) is a small malicious program that pretends to have a particular function, but that only shows its real purpose after execution and that purpose is often destructive. Trojans cannot multiply themselves, which differentiates them from viruses and worms.

* Virus
A virus is a small malicious program that multiplies and is capable to attach itself to other programs after being executed. It then causes an infection and causes various degrees of damage to your computer.

* Worm
A worm is often characterized as a malicious
