How to restore iPhone from old backup?

My phone got stolen last night and he erased all my messages before I was able to lock it. He tried to sell it today so I got it back. Anyways, I'm wondering if there's a way to recover my messages through my old backups? If so, can anyone guide me? The new iTunes is kind of tricky to me. I don't want to completely restore my phone and lose all my contacts and everything, was just hoping to get my texts back.

Is this a computer virus or something else?

So, I restarted my computer this morning, and when it turned back on, the internet explorer icon had been replaced by an IExplorer icon. I clicked on it, and it looked pretty legit--it said it was some kind of Ipad/Iphone/Ipod transfer thing by Macroplant. It also offered to update me with version 3.2.2, saying I already had version 3.1.5 (even though I never download or installed this thing). Even on the Start menu, internet explorer was replaced by the IExplorer icon. However, the real IE icon was placed in another spot on the start menu, so I can still access the internet. On my desktop, there's now a "uninstalled" version of IE that offers to install IE 8; it also says I already have a version of IE 8 and if I install it, I will not be unable to uninstall it. I read online that iexplorer.exe is a trojan virus, and I was wondering if anyone knew if I had it. I'm not sure, since it seemed legit and the icon only said IExplorer, without the exe. I'm not really good with computers, so I'm sorry if I'm not seeing something obvious. I was wondering if someone could maybe tell if I had a virus or not, or how that thing got onto my computer. Some extra info: someone told me to delete it. I deleted the icon, and then I uninstalled it from the "remove apps" menu. It then told me that not all parts had been able to be removed, and I would have to manually delete them (How?). Right after that, I got both a Microsoft error message (saying that "iexplorer.exe" needs to close) and a Macroplant error message. The Macroplant error message says it is checking for a newer version. Since the Microsoft error message says iexplorer.exe, is this the same as the iexplorer.exe trojan?

Added (1). Doruletz1999, I'm aware that IE and Internet Explorer are the same thing, BUT IExplorer is a different thing.

Added (2). And please guys, stop telling me to get a different internet browser. The person in my family who sets up new computers installs IE, so we all just use it. I'm aware that other browsers are better, but right now I just want to know about my problem/potential virus.

How long does it usually take for something to ship from Hong Kong?

I purchased a mic and an iPhone cover from eBay and it says that it has been shipped, but when I clicked on the details of the item it says that it is preparing shipment and the other item says that it has been accepted. The item description says that est.delivery will be on Tues Apr. 2 - Thurs. Apr.18, and so does the other one. I realized that the est, delivery was adding on a day. Should I contact the seller or just wait?

How to locate my iPhone backup on Windows Vista?

I've been looking online to see how to find my iPhone's backup on my computer in case I need to restore it. Everyone says that for Windows Vista this is how you get to it:

\Users\USERNAME\AppData\Roaming\Apple Computer\MobileSync\Backup\

But after I get to Users all I see is Default, Owner, and Public. I can't find any of the folders listed above except for Users. I even went into my control panel and set it up to where all hidden folders are shown, and they're still not there.
