I use ClamXav without any issues for at least 5 years.
Other good helper Application(s) that I use, I don't use any others, are the ones Marcel Bresink Software puts out. He has some paid/some free. I feel his software is very safe; it hasn't done anything harmful to my Macs. I researched and it came up positive.
His main product page is: http://www.bresink.com/products.html
I have been using his Tinker Tool System and Tinker Tool for at least 5 years. I'm not a tech, so I try really hard to keep everything simple. Some options he has I have never used/changed. He has plenty of documentation that is very helpful and recommended.
It might help.
Oh, and I wouldn't use anything Google either. Try using: https://startpage.com/eng/aboutstartpage/ as your search engine.
Hi. I'm slightly confused as to what you mean. What does ClamXav do? Is this an antivirus tool? If it is, as linc stated, apparently, virus software isn't *that* necessary on macs. I (i have no idea why) appear to have fixed the problem by using a different display. Nearly all lag has completely gone. (for now)
I'll try it like this for a few days and then get back to you.

Yes, it is a Mac anti-malware tool that is often recommended because by default it does not run any background processes to interfer with your computing experience. It only does what you tell it to do, when you tell it to. As Linc mentioned:
It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product.
Full disclosure: I participate in uncompensated tech support for the ClamXav Forum.
I'll install that and see if it affects the speed in any way.
Since it doesn't run any background processes at all out of the box, it won't. You can schedule a daily definitions update and / or daily scan if you want to. All other scans with the app are manual.
With the web site version, there is a real-time process called Sentry you can setup to watch selected folders if you feel you need that.
I think a clean install of OSX may be in order.
That certainly worked well for me when my Finder suddenly slowed down a couple of weeks after upgrading to original Mavericks. Quick and easy. Didn't touch any of my user files or third party software. I was back to good-as-new in a couple of hours or less. But yes, you do want to have a backup, just in case.
