I didn't realize MSE sucked that much. To be honest with you it's the first antivirus I've consistently used because it's free and it's just there. I've been perhaps very lucky or benefited from herd immunity because in almost two decades of having a PC I've pretty much never run an antivirus and in terms of bonafide definite viruses I'd say I get one per decade. Malware is another matter, though

I'm very careful with what I click and I use this PC for 90% of the time, just not 100% unfortunately.
