Hi,

 

I love malwarebytes, and for a while I have had only malwarebytes installed on my PC.

 

More and more people have recommended to also add a classic a AV, to work along with Malwarebytes.

 

Is this necessary? Why?

 

Are there AVs that don't work along side with Malwarebytes?

 

Thanks!

Hi PIERCE the 3rd :)

It is not necessary to have an Antivirus running on a system. If you mean "necessary" in a way of "you have" or else Windows won't run, properly, then no. However, you should always have an Antivirus installed up and running since it's one of the most efficient way to protect your system. It's the first layer of defence against infection and the program that can protect your system the most (after you of course). It should had been the opposite too. You should had started using an Antivirus way before Malwarebytes, since Malwarebytes is an Antimalware and meant to complement an Antivirus program. quietman, one of BleepingComputer's MVP in Consumer Security wrote a fully detailled guide on the best security practices to follow in order to stay safe and secure on the Internet, and also when using a computer. One of them, if not the first one is to use an Antivirus product, like you can see in the second part of his post here:

http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/#entry2316638

He also explains how to choose an Antivirus program that will fit in your needs in another part of his guide, here:

http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/#entry2316629

Lastly, he wrote a part on supplementing your current Antivirus program with an Antimalware program for additional protection (in your case Malwarebytes):

http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/#entry2413189

And Lawrence Abrams (aka Grinler, the Owner and Founder of BleepingComputer) also wrote a guide showing 16 tips to stay safe and secure when using the Internet and a computer, and using an Antivirus program is one of the top tip in it.

http://www.bleepingcomputer.com/tutorials/keep-your-computer-safe-online/

So yes, it's definitely "necessary" to run an Antivirus program on your system in order to stay as safe and secure as possible. To address your last question, Malwarebytes is an Antimalware program, which means that it's meant to run alongside any Antivirus program there is. So the logical answer to your question would be: no, every Antivirus works fine with Malwarebytes. At least, all the ones we know of that are known, popular and been in the domain for quite some time. If you were to ever encounter an Antivirus that doesn't play well with Malwarebytes, you can usually "whitelist" Malwarebytes in your Antivirus program and also whitelist your Antivirus program in Malwarebytes. If you want, once you'll have chosen your Antivirus program, just let us know which one you'll take and we'll let you know if there's any known issue between that program and Malwarebytes and if you have to make the adjustements mentionned above.

The following quote is a statement from the Malwarebytes Team.

Malwarebytes Anti-Malware is not meant to be a replacement for antivirus software. Malwarebytes Anti-Malware is a complementary but essential program which detects and removes zero-day malware and "Malware in the Wild". This includes malicious programs and files, such as viruses, worms, trojans, rootkits, dialers, spyware, and rogue applications that many antivirus programs do not detect or cannot fully remove. It is important to note that Malwarebytes Anti-Malware works well and should run alongside antivirus software without conflicts. In some rare instances, exclusions may need to be set for your specific antivirus product to achieve the best possible system performance.

You need both an anti-virus and an anti-malware solution for maximum protection.

An anti-virus program alone does not provide comprehensive protection and cannot prevent, detect and remove all threats at any given time. Anti-virus and anti-malware programs each perform different tasks as it relates to computer security and threat detection. Essentially, they look for and remove different types of malicious threats.

In simplistic terms, Anti-virus programs generally scan for infectious malware which includes viruses, worms, Trojans, rootkis and bots.

Anti-malware programs generally tend to focus more on adware, spyware, unwanted toolbars, browser hijackers, potentially unwanted programs and potentially unsafe applications.However, there can be some overlap in functionality and detection features depending on the program's scanning engine, how the vendor defines a specific threat and what Naming Standards are used. Anti-virus software is inherently reactive...meaning it usually finds malware after a computer has been infected. The security community is in a constant state of change as new infections appear and it takes time for them to be reported, samples collected, analyzed, and tested by anti-virus researchers before they can add a new threat to database definitions. Further, if you're dealing with zero-day malware it's unlikely the anti-virus is going to detect anything.

Thanks for the quick replies.

I will go over the links and install an AV.

 

Thanks again

No problem PIERCE, our pleasure :) Feel free to let us know which setup you'll end up with if you want opinions and recommendations.

Malwarebytes Anti-Malware does not target viral malware (file infecting viruses, macro viruses, etc), with the exception of certain types of worm (a subcategory of virus).

 

Malicious code appended, prepended or cavity injected by a virus into a legitimate file cannot be removed by MBAM. This can only be done by your Anti-Virus. 

 

MBAM does not target document files (.doc, .pdf, etc), media files (.mp3, etc) or script files (.bat, .js, .vbs, etc). MBAM, for example, will not detect a malicious XML macro downloader should it land on your computer. It will target the payload (in this case, the banking Trojan Dridex may be downloaded), but will not target the document responsible for downloading the Trojan. Documents or media files crafted to exploit vulnerabilities in certain software will go undetected by MBAM when they arrive on a computer, as will script files with malicious intent. The file encrypting ransomware KeyBTC, for example, uses a double-extension Javascript (.js) file to download various files used in the encryption process. This file would not be flagged by MBAM. 

 

MBAM was, and is to this day, designed to run in conjunction with your resident Anti-Virus. The programme excels at detecting zero-day malware that Anti-Virus software does not yet flag and reversing changes/modifications to the OS made by malware. With the sophistication of malware today in the wild, a multi-layered security solution that incorporates an Anti-Virus is essential for the everyday home user.
