I decided to go with VirusBarrier X6 after trying other free anti-virus software from another vendor, only to realize that "free" doesn't come free of problems. VirusBarrier runs on my Mac like I expect it should.
VirusBarrier X6 is robust yet has a very light footprint on my computer. The best part is that I can still use my MacBook Pro (w/ OS X Lion) when running scans! No lag or slowness occurred, even while running scans and listening to music at the same time I'm writing reports using MS Word. It's fully loaded with anti-malware features, two-way firewall, anti-spyware and proactive Internet security. The list goes on.
I also found out that Intego is typically the first to update their virus definitions when new malware is found. Moreover, the Mac experts at Intego are normally the first to discover any new malware or Internet threats that affect Apple computers.
Intego, as the only Mac security company focusing solely on protecting Apple products for over a decade, is the best choice for protection from malware.
ClamXav is nice because it's "free," but it certainly doesn't run on Mac OS X free of problems. This was the first antivirus I tried on my Mac w/ Lion, which was based on suggestions by others. However, I ran into all sorts of problems when running scans.
The first thing I noticed is that running a scan renders my computer useless. ClamXav slowed my computer way down, and that's saying a lot because my MacBook Pro is new. Frustrating, to say the least.
Secondly, I decided to add some exclusions to see if that helped ease the lag caused by this software. After running a few more scans, I found that ClamAV is ignoring all exclusions that I have put into the exclusion list.
For example:
.jpg
.jpg$ (as a regex)
These exclusions are "enabled," but I dont understand why then it still scans every singe .JPG file on my computer. Is this a bug? I'm not sure. But I do know its very annoying.
Thirdly, I found ClamXav's user interface to be confusing and more of a hassle to deal with than what I initially expected. I'm sorry to say it, but this software is bad. So I uninstalled.
[Version 2.2.2]
