I was checking my temporary internet files this morning and found a few things that I know I haven't accessed. For example, there are a few files named "searchresultsSBS", and when I click on it, it'll show that I "searched" for someone named "amanda iori", "web domain hosting", among other things.

I only use Firefox and found no suspicious activity when I looked in the history. When I opened up my Internet Explorer, however, there were records of my "visiting" other sites that I know I did not visit. Most were visited when both my husband and I were not even home, or sometimes when I was on the net. I am currently using a wireless adapter to connect to a wireless router, which is located in another room.

Is it possible that someone is "sharing" our internet connection? If so, is it also possible that this person's sites are being recorded onto my computer and therefore showing in my history folder and in my temp internet files??

Any advice would be greatly appreciated. Thank you!

While it's possible that someone is sharing your internet connection, any sites they visited would show up in the history on their computer, not yours.

It's more likely that you have a virus or other form of malware that is targeting internet explorer and planting files in the history. It may have change the IE homepage, too.

Run full virus and adware/spyware sweeps. I almost guarantee you'll find something.
