Anti-virus software only has a place for the average user who are not tech savvy and go to places they should not. Furthermore, they usually only detect simple infections and adware, and completely miss the more threatening infections that require manual or a more powerful software like combofix to produce results, both of which your average users do not know how or are too scared to run. Modern day browsers are pretty comprehensive in their security features, so for a person who knows how to browse smartly, anti-virus softwares are useless.
Yes, there is no such thing as 100% protection, but being well informed is the best anti-virus there is.
I would be amazed if a tech group cannot easily switch software, especially if said software has vulnerabilities that can compromise the company's security. I have not worked for very large companies like google. The company that I work for is only a few thousands strong, but we have switched video/instant messaging software a few times and even use multiple software as necessary without any problems at all. There is a difference between being unable to switch and people not wanting to switch because they are used to whatever.
They hardly only detect
simple infections and adware, perhaps if you actually made use of anti-virus applications (or well a good one) you would know this.
But I'm just going to let that all go, the fact you're claiming you've worked for Google yet you're stating all this s**t gives me an impression you're either attention whoring or trolling, and I'm not going to pander to your intent for attention anymore. At the most, if you did work for Google I can understand why you likely don't anymore given your interest to give disinformation to people.

I am using McAfee right now, but it isn't being very reliable.
To get back onto the original topic (which I didn't even realize I never directly answered), despite what some might claim, an Anti-Virus lined up with some other software can and generally will prevent a majority of things, and a good one won't normally muck up your resources in the slightest either.
My personal combination of things tends to be a mix of
Avast! and
Comodo Firewall (
just the firewall, not their full suite) installed at the system level tend to do wonders, Comodo Firewall can be slightly more technical but it's also a hands-on tool for safer control, in the off chance something might get past avast chances are Comodo would catch it, at the very least when it attempts to run and communicate externally as Comodo prompts any outbound or inbound connection requests that aren't otherwise manually white-listed or outbound from a pre-determined "safe" program, such as say your web browser of choice.
At the browser level, if you use something like Firefox or Chrome, I'd suggest looking into the
Adblock Plus plug-in as well as the
Privacy Badger plug-in, those help not just prevent potential points of attack at the browser level but also offer some level of privacy control in blocking tracking cookies and stuff with Privacy Badger.
