One way to avoid some of the issues is to designate websites as trusted sites. If they're trusted, you can go to them and avoid some of the issues -- once a site is trusted, then IE won't check on some of the security issues. You're telling it in advance the site is OK, and that's good enough for IE.
It's simple to make a site trusted.
- Click on "Tools"
- Click on "Internet Options."
- Click on "Security."
- Click on "Trusted Sites" (see picture)
- Click on "Sites."
- Enter the web address of the site you want to make trusted.
- Click on "Add."
- Generally, leave "Require server verification" unchecked.
- Click "Close."
Now that site is trusted.
