Use the two programs below to clean up and check for malware. That is the two most common causes. Are you getting any warning messages?

Remove temporary files, logs, cookies, etc. by using Ccleaner. Do not use "Advanced Settings" or the "Issues" button. Use only the default settings. http://www.ccleaner.com/

Install Super Antispyware free. Run it in safe mode. Allow it to quarantine whatever it finds.
