Last crash report sent was in March. Since then error message appears "there is a problem sending crash report" and no report is sent. I have gone thru the troubleshoot list a couple of times and it's fine for a few days and then starts crashing again. This is a Windows XP machine with AVG Antivirus, Spybot, Malwarebytes, and CCleaner installed. Frequent checks are done using these programs and usually the only things found are cookies and files left in history, nothing serious is found.
