By losing things do you mean your saved passwords and bookmarks and all that? If so you can transfer most of that kind of thing to another browser like Firefox which is what I've used for a while now. There's Opera that's not bad, and I haven't used it but Google Chrome's out there now. The biggest problem with fox is they tend to put out updates that break most of your plugins, but that's easily remedied. All-in-all though, it's safe. Much safer than Explorer certainly. One of the newer browsers is supposed to be the safest of them all, but I don't remember which one it is. It may be Google Chrome, which is also supposed to be stupid-fast too.
