What I'm retired from is anti-virus.
The most important thing to remember is that the home versions of McAfee and Norton are horrible (corporate versions not so bad)
Did an eval exercise just before I retired where Kaspersky came out very well (against Sophos and Mcafee) but again that was the corporate version
If I could get it free I'd try the home version
For years didn't bother myself, as we knew what not to do, but the infection methods have got cleverer. Used to use AntiVir when doing cleanups, so am trying that, but it seems to slow down the system qute a bit and occasionally panics and blocks legit web content. So I let it run during boot-up where it ought to catch anything that's got into the OS, then switch it off; and do a full scan every month or so, which invariably throws up a false positive.
Got the MiL on AVG. She's had it years, not let her down. I hear it occasionally slows stuff down, but it's hard to tell on her system, it's such an underpowered mess anyway.
