wJQs.exe Good file or Bad?

I found wJQs.exe while checking McAfee log file which said it was prevented from accessing the internet.  Search results found it in 3 places, Windows\Prefetch,

C:\Documents/settings\myname\localsettings\temp, and sorry but can't remember the other location.  I verified that mcafee was up to date and scanned several times but didn't detect anything.  I cleaned out cookies and now only see it in C:\Document\settings\myname\localsettings\temp.  I also found DLLHOST.EXE in 4 locations--3 were in lower case and 1 in uppercase letters.  The one in uppercase was also in windows/prefetch and was 60KB, and in properties the description was "unknown".  The others were 5.0 kb and description was "COM surragate" and I believe they were located in C:\Windows\system32, and in c:\windows\servicepack.   I now cannot find the larger file but then, I don't know what windows\prefetch is so maybe what I am seeing is normal?   I search for wJQs.exe on McAfee and found nothing but when I googled it, I found some things that scared me on both of the files I have mentioned.  I downloaded Hijackthis as the instructions said and is shown below, I hope I did it correctly and will appreciate help if I have something I should not have on my pc.
