Why is it that everytime I open a window, it closes on me within a few minutes?

I expect it will close on me any minute now.Every application I use, whether I am typing an email or browsing the internet, closes without warning often in the middle of doing smething.My connection is good.I use cable internet.My virus protection says I am fine.So, what is with every window I open closing minutes later?

If it only happens with the internet, it could be your internet subscriber that's messing up your connection. Or if it's even opening documents you could have a virus regardless of what your virus protection says. For instance I have pop up blocker on all the time and sometimes pop up's still come up. You could need to upgrade your Virus protection. Or, try shutting your computer down, and turning it back on about 20 mins from now.
