Q: Performance issues since upgrade

I am on a late 2011 MacBook Pro and am having severs performance issues since upgrading to Mavericks. I fear my issues may be related to company installed anti-virus (which I cannot remove), but I was hoping someone could look over my EtreCheck for other potential solutions.

One really odd issue I am having, which I cannot seem to find good information for on Google, is at least 4-5 times a day my Mac just stops. No beach ball, no anything, for about 1-5 minutes. Then it's fine. Maybe just me grasping at straws, but it seems related to a when webpage loads a bunch of images? I always use Safari btw, but testing other browsers, like Chrome & Firefox, it happens as well.

I have also removed TotalFinder and have noticed no improvement and still have the above issue.

Thanks in advance!

Here is my EtreCheck:
