How to fix browser window problems?

[henry]

I'm using Windows 7, Firefox 27, and Google Chrome, and I'm trying to figure out why my browser window(s) keep saying "Not responding" or the browser window "shakes" side-to-side every time I play a Flash-based game, or just browsing the web, period. Some people suggested I try shutting off Flash (Google Chrome has a separate Flash app) and I've done that, but it still does the same thing. I'm starting to think that I might have malware or spyware, but I'm not real sure. Any ideas?
I think it's one of my Flash player apps, but I'm not sure which one.

If it's not responding then you are losing Internet through your wifi[ or whatever you use]. Mine does this and i have to turn my wifi off, Reset it and turn back on.

I get Not Responding from time to time in IE 10.

Sometimes it takes a few mins in that state, then the site does respond.

Sometimes I click Recover, but that usually closes IE, as does the Back button.

As I recall, I got more Not Respond when I had IE 11 briefly.

I heard there were compatibility probs w/ it and some sites.

So I uninstalled it, and IE 10 automatically become my browser again.

If Firefox 27 is a recent update, incompatibility could be a prob.

I think malware would do more damage than Not Respond.
