The safest way to browse is to use Firefox or another non-Internet Explorer / ActiveX supporting browser. Microsoft provides directions on how to browse safer using their products. I highly recommend that you follow this if you want to continue using Internet Explorer. Here is a brief explanation:
- Set your Internet Zone security to High
- When you trust a site, add it to the Trusted Zone. Microsoft recommends you run the Trusted zone at Medium security -- if you do, you will have problems on some sites. You need to move it at least to Medium-Low.
- Read all email in plain text (not HTML).
