HI,
Download and run both of these tools and show us the logfiles. If they won't run, then redownload and rename before saving to your desktop.

1.  Download Malwarebytes' Anti-Malware to your desktop, check for the tool's Updates before running a scan.
http://www.malwarebytes.org/mbam.php 
 

2.  Please download ComboFix by sUBs:
http://download.bleepingcomputer.com/sUBs/ComboFix.exe 
You must download it to and run it from your Desktop
Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
Double click combofix.exe & follow the prompts.
When finished, it will produce a log. Please save that log and attach it in your next reply by pasting it in the "Code Snippet" or "Attach File" window.
Re-enable all the programs that were disabled during the running of ComboFix..

Note:
Do not mouse-click combofix's window while it is running. That may cause it to stall.
CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.


If needed, here's the Combofix tutorial which includes the installation of the Recovery Console:

Reformatting and reinstalling is always the safest solution and with not so many programs to put back that's the best solution.
<<<"running combofix on machine then manualy deleting files fixed issue on another machine">>>

Combofix has a script function to delete bad files that weren't deleted in the first run that's why we always ask to look at the CF log to make sure it's clean.
Glad to know the issue on another pc is fixed.

To uninstall Combofix:
Go to Start > Run and 'copy and paste' next command in the field:

ComboFix /u


You can then close this question please.
