I wouldn't. My recommendation for anyone who has a concerns about malware is to get a reputable and lightweight (preferibly free) malware scanner such as Sophos Home Edition, and use that to periodically scan the system for malware. This software should not adversely affect your system (though there is always a potential that any software addition to the system can case issues), and I have installed it on many systems with no problems that I've seen.
should i run malwyrbytes or spybot to check for viruses or spy ware on my imac os x?
Are you running Windows on your Mac?
Malwarebytes does not run on OS X. Here's what they have said about that.
There is no Spybot for OS X. Note what they say about that here. Most Mac A-V software doesn't check for it either since Spyware generally requires physcial access to your computer or shared access that you would have to approve over the network.

I suggest that if you decide to use Sophos, use the recommended (default) settings. This enables the "on access" scanner, which automatically scans files before they are opened, in the background. This is a very "lightweight" process, using negligible system resources & taking only a tiny fraction of a second to complete.
I have been using Sophos Home Edition since it was first released, on several different Macs running several different OS versions. I have never had any problems with it whatsoever.

7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Linc is entitled to his opinion but I suggest taking any such overly broad statements as "they all do more harm than good" with a very large grain of salt. To begin with, how could this be anything but speculation unless he (or anyone else making the same claim) has tried all the available commercial products, examined their code, & discovered some weakness in the processes they run?
And while it is true the databases are always going to be out of date, it is not true that most of the danger is from "unknown threats," which are most often referred to as "zero day attacks." The likelihood of a typical Mac user encountering one of these attacks is vanishingly low. That is because their value lies in their remaining undiscovered by the security community & releasing them "into the wild" would destroy that value. For this reason they are almost exclusively used to selectively attack very high value targets like financial institutions, companies with lucrative trade secrets to protect, & sometimes even governments.
They, & the vulnerabilities they exploit, are closely guarded secrets, revealed if at all only to a select few willing to pay large sums for them and trusted not to use them so indiscriminately that they would be discovered. When they are discovered, for instance by security firms (some of which employ people posing as criminals willing to buy them) or by other criminal hackers who package them into "crime kits" to sell to still other criminals, "zero day" has passed.
This is the time of the greatest danger to typical users: the secret is out, the attacks are "in the wild," & it becomes a race for Apple & all the other security software providers to implement & distribute counter-measures before typical users encounter them. Betting on Apple alone to do this in a timely manner is good; but betting on Apple plus a commercial security outfit with a good track record is better.
It is really pretty simple: since it is a race, the faster you get an effective counter-measure running on your system the better protected you are. Among other things, that means getting database updates ASAP from whomever provides them & making sure they are applied to the widest possible variety of software that you might encounter, whatever the source.
Jerry, having crossed over from the windows world as well.... I have noticed you have "solid feed back here"
as for myself I have noted that at times there are apple purists (stay with apple based products and software and you are safe - claimxav av for windows cross over and your fine).. There are other people that are cross over based (win/mac) which look at everything from those perspectives focusing on mac and the win relationship (cause and effect), You also have the ability to run windows on a mac from bootcamp or a virtual configuration.
