Antivirus and Malware Software

Is it reasonable to run both Symantec Client Security and a malware scan software like Malwarebytes?  We seem to be getting clobbered with bad stuff all of a sudden, even though end users PCs are fully patched and running current AV/Firewall defs.  I was thinking of implementing a malware scanner but didnt know what type of performance hit we would take or whether that was even feasible.

Thanks.

yes you can use both. As malware (atleast the free version) only runs when you ask it to scan.

Ive had no problems running malwarebytes and Mcaffes


Do you allow users to bring in Flash drives? Or give them the ability to load active x controls and things of that nature? That could be part of the problem

Yes you can run both. It's when you run two anti-virus suites side by side that you can run into problems. Just make sure that you read the User Agreement for Malwarebytes. It is free for personal usage only. (FYI)
Their corporate discount licensing information can be found here.

I would also suggest that you run your scans in Safe Mode when possible. If not, (and as I'm sure you know) it only takes one infected system to keep propagate bad code to other systems.

Hi,

You can, but you may face problems. The recommended way is to use one full antivirus software that is installed and monitoring (Kernel / File System / Memory / Boot / Critical areas). Running another antivirus may harm your system, because it will try to install some modules that would conflict with the first AV. So, use a command line version would not affect it. CL AV will scan memory & file system without installing any modules.

XM..
Could you explain in more detail what you mean with the command line scanning.  We are currently running Symantec Client Security and it is letting malware slip through (granted some of this is just plain user error) but nonetheless, I need to implement something in addition.

command line or stand alone antivirus softwares don't need to be installed and integrate with the system. Most famous antivirus products have a command line version which can be used in situations where you can't run the gui version or you want to write a script/batch to automate the scanning or use it with a third-party product (ex. antispam / web filtering). Or from inside Windows safe mode.

The bottom line, it's not recommended to run two antivirus products that need to install some files and kernel modules. This will damage / slow / disturb your OS.

Okay, so I know I can't run two AV suites, but is malware software considered AV?  I, personally, would not consider it as such.  Most of those discussions are referring to AV suites (i.e., running McAfee and Symantec together).  This is not the scenario.  I am considering running Symantec Client Security and malwarebytes together with a paid version of malwarebytes so I can have active scanning on - just not sure if that will cause a problem.

XM - thanks for those references, but most of those were referring to individuals who wanted to run two separate AV scanners.

Thanks.

I haven't used Malwarebytes ... So, If it's a stand alone software..you can run it with no problems
