free antivirus for mac os x lion 10.7.5 avaia

I don't need FaceBook integrated with my OS, nor do I need new 'features' that make my Mac act like a phone! I need an OS update that doesn't break my system and make me waste about 18 hours time over the past 2 weeks ( >3 of those hours working on the phone with Apple ). I wish that who ever runs Mac OS software development would say 'Hey, instead of taking the time to implement like 200 new 'features' into another major release, we just took six months and actually worked to fix a bunch of bugs! SW QA at Apple is getting worse and worse. something we are sort of calling '10.7.5.1' or whatever. I cleared the infected files, reboot and still cant install. It says I have 12 infected files, and over 160 unable to be scanned. I installed it on an external bootable drive with the same OS on it, and ran a scan on the drive from which Im getting errors. So instead of being forthright about this and saying 'we really screwed up here', and calling 10.7.5 dead in the water, and releasing a point update to 10.7.6 (which is the RIGHT way to handle SW CM), instead we are copping out and releasing. I am running OS X 10.7.5, and it wont let me install Avast. (However if you called us and got a level-2 tech on the phone, they would admit to you off-the-record that Apple was aware of this problem). However we didn't have the integrity to admit it even though there were tons of discussions about this all over the web and on our own discussion boards. Well, we screwed up big time with the 10.7.5 update, and we have known about this for a few weeks.
