According to your post, I think your PC is clean and there is no need for extra check.
Just to do some junk removal, if any.
Please download Junkware Removal Tool to your desktop.
§ Shut down your protection software now to avoid potential conflicts.
§ Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
§ The tool will open and start scanning your system.
§ Please be patient as this can take a while to complete depending on your system's specifications.
§ On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
§ Post the contents of JRT.txt into your next message.
Empty your temp folders using TFC (Temporary File Cleaner)
§ Please download TFC by Old Timer and save it to your desktop.

§ Save any unsaved work. (TFC will close ALL open programs including your browser!)
§ Double-click on TFC.exe to run it. (If you are using Vista or above, right-click on the file and choose "Run As Administrator".)
§ Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
§ Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway allowing Windows to load normally (not into Safe Mode) to ensure a complete clean.
