Can you share the name of your antivirus?
Sure.
I use Avast Free version 7.0.1474. I do a custom install, installing only the File System Shield and Behavior Shield, disabling everything else except the streaming definitions updates. If you go for it then take care to install it offline, otherwise it will auto update the program to the latest version (which I think is bloated with loads of unnecessary stuff that is n't needed and does n't work particularly well). Once installed, be sure to disable program updates (as per the reason above). Then you can go back online to update the virus definitions.
It works well for me as part of a multilayered security, occasional false postives, but apart from that it does the job. Your mileage may vary.
You can still get version 7.0.1474 here...
