What's the difference between the two?
Do I need both?

Umm, one is for spyware, the other for viruses. They are not the same thing. Maybe you need to be more specific.

Anti-Spyware

Anti-Malware

Yes you do need both Anti-Spyware along with Anti-Malware software programs to keep your computer running up to speed. - Security tips here

AntiVirus go after viruses, trojans, worms, etc.

AntiSpyware target spyware and adware.

Most AVs these days target spyware/adware to some extent, but for the most part, both an AV and AS are needed.

Since the introduction of suites, the security software maker's have pushed us to these "all-in-ones" to monopolize our money. The push is evolving into anti-malware tools that do it all. There is some sense to this, since the "act" of scanning files, memory, and disks is the pretty much the same, whether the target be virus, worm, Trojan, keylogger, or whatever type of malware. So from a "business sense" - it costs of lost less to build one scanner and market it for two uses (viruses and spyware). But from a security standpoint, using a single scanner introduces several "single points of failure" - I copy from one of my stickies:



Do not forget that none of the security software makers want to rid the world of malware. That will put them out of business. Do NOT trust a single one.

This was a hint that we need to show users the difference and why they need both but only have one AV running.

I couldn't tell you how many OP's thought their Anti-Spyware program was their Anti-Virus program,

It would be nice if we had a post to point the OP's to.

Just a thought.

Greetings LD

It seems odd that you of all folks would ask that question. Seeing the number of years you have been at the forefront of removing and educating others in the removal of malicious code from computers.

I am thinking you are not looking for an academic answer from us (the group here at WTT). , A few google searches would bring you a wealth of answers and probly better written than anything I could create. I might even bump into one you may have written.
The average user doesnt know the difference in malwares and the software either. All they know is that the computer isnt doing what they want when they want it to.

Perhaps you are after what we (the group here at WTT) thinks is necessary for the best protection of a computer? You know the answer to that one as well. The best protection is the user themselves.

The vast majority of malicious code is coming from the catagory of "spyware" and its purpose for being has blurred overtime, but still is primarily about financial gain. Its about engineering you into giving up money or valuable information. Either voluntarily or working by stealth. Spyware, a subset of malware, is about financial gain.

Virus by its nature is about distruction, compromise of networks and loss of data, corruption of operating systems. Usualy done for bragging rights, revenge, or retribution of some percieved wrong. (social or economic) Not about financial gain but distruction and noteriety. Virus, a subset of malware, is about distruction and crippling functions. Usually not about financial gain.

LD you know more about means of infections than I will ever hope to know. You have seen Malware (virus and spyware) evolve into rootkits, zombies, identity stealers, social engineering vectors. They at one time used different means to infect a computer. You needed several different tools to deal with it. This still has not changed.

But now they (virus/spyware) are using simular means of infection and have crossed over into each others behavior and effects. Both are being created for financial gain and distruction at the sametime. They represent a blended threat now. Not quite virus or spyware. The malware has become more complicated in eluding detection, persistance, and removal. New threats are arriving quicker and Anti-virus software alone, cant get in front of malware to be effective as a sole protector.

Although the Anti-virus software have made great strides in addressing the "spyware" threat by creating suites, they are not enough by themselves yet. Thus the need of separate anti-spyware software for now. Plus specialized tools and user education.

So I trust I have answered your question LD with enough. I would be more than happy to elaborate more if you wish

Regards

Kaz

So much for composing this before you got your explanation in LD, If you like I can remove this or just pretend you had not posted yet.

What? You mean you think there should be a post we can point to to educate our users on how to protect themselves - you mean like a post that teaches Practicing Safe Computing? That would be nice. I am still waiting to see the list of approved items we can recommend. Can we expect to see that soon?

I have one also pinned in Tech Tips and in my signature called Security tips.

It might be a good idea to post the Preventing Malware - Tools and Practices for Safe Computing, that Doug and I worked on with everyones help, Topic in the Malware Removal Forum or another forum as well.

Those are ALL very good prevention topics we have.

Regular users sometimes don't understand the difference between the two types of programs needed.
Anti-Virus / Anti-Spyware.

I was looking for something simple to point OP's to like the below.
IMO it could be a little better written for the Spyware part, adding Anti-Spyware programs like s/he did in the Virus part.

Hi LDTate,

Would you like me to come up with a tutorial explaining the difference?

Sure. Give it a go

Thanks LDtate, I will get to work tonight, and should have a rough draft for you by tomorrow night.

After a small amount of reseach here is a post you may approve of to point the OP to.
Understand the Difference - Microsoft Security

Then I got the extreme to the above - No difference and again here

My last quote to post: from here Posts # 1 and 2

I like the Microsoft link, but for the "extremes" links, those comparisons are between malware and spyware, not viruses and spyware. And in either case, the authors are wrong, there is a difference. Spyware is malware, but malware does not have to be spyware. Malware, is a catchall term that includes all categories of "malicious software" to include spyware, viruses, worms. etc.

Thanks Bill for your help and advice with this, as my signature says, I am learning each day.

Here/Is this a better description of what I was after. Differences between Viruses and Spyware

I would not edit my last post and change the links, as then your reply would not be relevant to the thread so I added this link for further comment.

Rough Draft sent to LDTate

Post it and lets see what others think.
You could also post it in the Malware Team forum.

Hi LDTate, posted it in the Malware Team Forum


What is the difference between AntiVirus and AntiSpyware?

Before we explain the difference, it is important to understand what viruses and spyware are:


Viruses are malicious pieces of software that once on your computer, they infect it in many different ways. A computer
virus is similar to a virus that infects people. When you get sick, you come down with a set of symptoms. For a computer, when it gets "sick", there are symptoms that occur as well. One way to infect your computer is to find files to infect. Viruses also can spread from one computer to another, infecting files as they go along. Once you’re infected you need to have the virus cleaned by AntiVirus software, which will disinfect the virus, making your computer "healthy" again.

Spyware is a malicious application that records your personal information, and then sends it back to the spyware author, who then can broadcast your information to others. There are also applications called Rogue AntiSpyware that tricks you into thinking that it is legitimate, and will help protect you. But what it really does is cause you to get infected, then it tells you that your computer is infected, but you have to pay them, the ones who infected your computer, to remove the so called "infections" on your computer.


So now to get to the difference between the two:

AntiVirus software target mainly viruses, worms, and Trojans. AntiSpyware usually goes after spyware and adware, as well as Rogue Software. Now-a-days, most AntiVirus software does target some spyware, but it is a good idea to still use AntiSpyware software, which is designed specifically to spyware.

The important thing to remember is that both AntiVirus and AntiSpyware are needed to adequately protect your computer from all of the various types of malware out there. Malware is a term that stand for malicious software, and is used to describe anything that tries to harm your computer such as viruses and spyware. Anti-Malware software, is designed to go after what both AntiVirus and AntiSpyware software targets.

Here is a list of free AntiVirus software (only choose one, having more then one AntiVirus on your computer at one time is dangerous)

• AntiVir Personal
• AVG Free
• AVAST!
• PC Tools AntiVirus

What is the difference between AntiVirus and AntiSpyware?

Before we explain the difference, it is important to understand what malware is:

Viruses is a broad term to describe malicious pieces of software that once on a computer are often able to infect it in many different ways. A computer virus is similar to a virus that affects humans. When you are sick, you often display a set of symptoms. In the case of a computer, when it gets "sick", there are symptoms as well (popups, programs stop working properly, redirection to unknown sites, etc...). As some human viruses seek out cells to infect , some computer viruses infect your computer by attacking legitimate files. Some viruses can spread from one computer to another, infecting files as they go along as seen in human viruses like the cold virus which can move from one host to another. Once your computer is infected you need to have the system cleaned by AntiVirus software, which will “disinfect” your computer, making it "healthy" again, in most cases. Unfortunately, at times, the damage done is so severe that the only recourse left is to reformat and reinstall.

Spyware are malicious applications that record your personal information, then send it back to the spyware author who is then able to share that information with others. There are also applications called Rogue AntiSpyware that attempt to trick you into thinking that they are legitimate programs that are there to help protect you. However, their main purpose is to infect your computer and convince you to buy them, in order to make your system “healthy” again.

Today it is very hard to distinguish what is a virus from spyware, so we use a general term called, Malware:

Malware is a term that stands for malicious software. It is used to describe anything that tries to either harm your computer such as viruses and spyware or installs itself without your permission with the purpose of selling you something like Adware. Once just a major annoyance to the user, malware has evolved into a major concern for every computer user whether they be you and me, big Companies or Government agencies. Today, Identity theft counts for the loss of billions of dollars worldwide. It is now a major tool used in industrial spying and a threat to the National Security of all nations.

For those of you wishing to find out more about the differences between the different types of malware, I strongly recommend the following article which is required reading in our Classroom and comes from the Kaspersky site: Viruslist.com - Malicious Programs Descriptions


So now to get to the difference between what an Antivirus progam does versus the role of an Antimalware program:

If the above explanation still leaves the waters slightly muddied for you, you are not alone. "Spyware" and "Virus" are words that are commonly used in an interchangeable manner. It is often difficult to easily tell the difference between an antivirus and an antispyware program these days because all these different tools that were once very specific as far as the types of "Malware" they detected now often overlap each other as far as coverage is concerned. The general consensus today is that the best protective measures against all that “scumware” out there require the use of both a good AntiVirus and a good AntiSpyware program providing Real-time monitoring.

Here is a list of free AntiVirus software (only choose one, having more then one AntiVirus on your computer at one time is dangerous)

• AntiVir Personal
• AVG Free
• AVAST!
• PC Tools AntiVirus

As previously mentioned, it is also a advisable to install an Anti-Malware tool such as Malwarebytes' AntiMalware to complement these excellent Antivirus softwares.
