Hi Nicolette,
Your computer has some nasties on there for sure. ComboFix did remove a a commercial spy/keylog program
These entries indicate that;

C:\WINDOWS\system32\acespy
C:\WINDOWS\system32\acespy\__acelog.ndx
C:\WINDOWS\system32\acespy\systune.exe

Here is an explanation of what this is;
Programs designed to monitor user activity. May be used with or without consent. Because it is sold commercially, many anti-virus vendors do not detect them. The most common form of a commercial monitoring tool comes in the form of a keystroke logger, which intercepts keystrokes from the keyboard and records them in a log. This can then be sent to whoever installed the software, or keylogger, onto the machine. Some Commercial Monitoring Software may take screenshots, or video and send the information to an outbound connection.

AceSpy monitors PCs by taking screenshots, keeping key logs, including chats, e-mails, web sites visited, searches performed, and more. AceSpy is completely hidden to the PC user, and the installer can have reports sent directly to their e-mail address. Keywords that specified by the installer trigger the program to send the installer instant alerts. Also the installer can set keywords to close a web browser if it encounters any of the listed words.
From their website:
"AceSpy is PC spy software for home or office use. Secretly see everything your spouse, child or employee does online. Instantly forward their emails and chats to your email address. Block web sites by keywords or site addresses. Get an hourly report email containing everything they do."
I am sorry to say but one would assume that somebody has pruposely installed this on your computer since it is a program which must be purchased in order to install it and use it.

Please run the ESET NOD32 Online Scanner again and attach the ScanLog with your post for assistance.
-- You will need to use Internet Explorer to to complete this scan.
-- You will need to temporarily Disable your current Anti-virus program.
-- Be sure the option to Remove found threats is Un-checked at this time (we may have it clean what it finds at a later time), and the option to Scan unwanted applications is Checked.
When you have completed that scan, a scanlog ought to have been created and located at C:\\Program Files\\EsetOnlineScanner\\log.txt. Please post that log for us.
