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

https://skydrive.live.com/#cid=455E9E19C61D7BD1&id=455E9E19C61D7BD1%21117&sc=documents

Uninstall SpyBot, if you used the TeaTimer module, undo any changes it may have made, before uninstalling.

Nero 9 also appears to be causing problems, as does Panda AV

Your Sky Drive is now working. When I looked at your Event log I encountered some technical  difficultoes but Palcouk seems to have managed better.

You do appreciate that it was not me who asked you to post what you did. Event Viewer reports are a good way of trying to resolve problems. My intervention was purely to assist you to use your Sky Drive. I would have expected Zig Zag to follow up but he has not so far.

I have to do paid work this afternoon but I will have a good look through your reports this evening.

Re:  Nero 9 I installed Visuall C++ 2008 and 2010.

I don't use Nero 9, but if I need to do any disc-burning, then I might need to use it.  I'm surprised that Panda IS 2012 is causing problems.  By the way, does anyone know anythign about this warning?

Its showing a problem with windows search service

I would uninstall Panda, Nero, Spybot if you havent done so allready. Reboot, then run disk Cleanup.

Then run the system file checker

After which clear your Event logs, so that in the event only new ones are shown (you were showing some 9k events)
