I'm running Win7 64bit and my IE 8 browser's search provider had been corrupted by a program, according to an error I receive. Because I use Mozilla, and I'm running a fairly new PC, I figured the search provider may have been some Dell-based provider, and I thought nothing of it. However, I decided to investigate anyway. I did a small search and found out that it may be born from a BHO, so I downloaded BHORemover and found an "unknown" BHO listing, comprised of a string of alphanumeric digits similar to a registry entry. Considering that it was unknown, I attempted to delete it via the program to no avail. I looked in IE's options to see if I could see it listed in the search provider section. Nothing but bing was listed. I then downloaded HijackThis and ran a scan. The unknown BHO showed up. I clicked to correct the problem and ran the BHORemover again to check for removal. The unknown BHO didn't show up. I re-ran HijackThis, and received an odd error message:
"For some reason your system denied write access to the Hosts file."
The message is longer than that, and I can transcribe the entire message if needed. I assume the error was a result of the deletion of the no-name BHO. HijackThis doesn't show the no-name during a scan, but has the BHO in its "backups" tab. To be safe, I ran a Malwarebytes and McAfee scan and both came back clean.
Should I be worried?
Thanks in advance, and I hope to hear from someone soon.
EDIT: I should also note that I've reset my IE settings under the "advanced" tab in internet options.
