What does 'possible heap corruption detected' mean, when listed in the Event Viewer?

Emma

I have found Event ID: 3036 errors hard  to resolve. Windows Search is difficult to configure.

This note might be worth following up, especial with heap corruption in mind:

Errors details: "The URL was already processed during this update. If you received this message while processing alerts then the alerts are redundant or else Modify should be used instead of Add. (HRESULT : 0x80040d0d) (0x80040d0d)" - One user had his Windows 7 system freezing at startup and this event being the last one recorded in the log. After several other troubleshooting attempts, he replaced the RAM on that system and the problem was fixed.

I would check your RAM.

Ran the System File Checker and Windows Resource Protection didn't find any integrity violations.  Does this mean that the computer's system files are ok?

I much prefer Panda as it has cloud technology and to be honest, I don't trust a free internet security program.

You could try AVG Free or Microsoft Security Essential which are Freeware. I use AVG Free.

I have removed Spybot, which is all I can do.
