griflord, give Malwarebytes' Anti-Malware a try:

Please download Malwarebytes' Anti-Malware from Here or Here

• Make sure you are connected to the Internet.
• Double-click on Download_mbam-setup.exe to install the application.
• When the installation begins, follow the prompts and do not make any changes to default settings.
• When installation has finished, make sure you leave both of these checked:
• Update Malwarebytes' Anti-Malware
• Launch Malwarebytes' Anti-Malware

• Then click Finish.
• MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
• If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
• On the Scanner tab:
• Make sure the "Perform Quick Scan" option is selected.
• Then click on the Scan button.
• The next screen will ask you to select the drives to scan. Leave all the drives selected and click on the Start Scan button.
• The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
• :
• When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
• Click OK to close the message box and continue with the removal process.
• Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
• Make sure that everything is checked, and click Remove Selected.
• When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. :(see Note below)
• The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
• 
  Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

alright bugbatter iv done it and it seems to work. i thank ya. the warning at the bottom of my screen disappered. im wondering if i should do a full system scan.

Glad to hear that it seemed to fix the problem.
Just to be sure nothing else is hiding in there, it would be good to do a follow-up Complete (rather than "Quick" ) scan.
