Been using Eset total security for years now, it runs in the background nicely and haven't had any reason to complain about it. I honestly thought anyone who was into computers knew to stay away from Norton, I absolutly hate the thing
I've used 'Antivir' since being on the net, seems to have done the job. Never had a serious virus outbreak it doesn't get in the way of anything. Just goes for an update once you get online and that all I see of it unless it finds a dodgy file
I use AVG Pro but with the firewall off as its useless well its good just blocks to much and messes with my VMware to much and if some thing goes wrong I start up Malware Bytes and scan with that and it always fixes up my issues.
