They are making the program too bloated. There's no reason why the program needs current hardware to run. It's not like it's the latest gaming engine or anything. If it ran fast 5 years ago, it should run even faster. It's not like AV suites do anything different now compared to 5 years ago. They can do it, they just don't care about it. And not enough of us make a stink about it to make them care, so that's how software eventually becomes bloated.
And the program is getting worse. The last two version don't "react" properly, in my opinion. There are many times when I'll click to update the signatures, and it lets you press the button, but nothing happens. Then it starts several minutes later. And the download speed of those few megabytes of signatures is really slow. And sometimes, it will detect something, and that big button turns red. So I click on it to fix it, I confirm "Neutralize" or whatever option is shown, and even after confirming a couple of times, nothing happens. Then I keep clicking it and nothing happens. The button stays red. Then i come back a few minutes later and it's green again. But I have no idea what is happening. Am I crazy to expect something to happen when I click a big huge red button that says "Fix it Now!"?? I hate bloat so freaking much.
I get such enormous pleasure when I find a software that is simple and fast. I love it when I click on things and the reaction time is really fast.
