Megauploader toolbar is basically an Alexa toolbar.
That is regarded as 'greyware' by Symantec - not malicious,but irritating.
All files should be marked as 'Alexa'.
Greyware will usually uninstall when asked to do so.
One way to test it,is to type some random letters into the address bar
press go/enter and see what page your directed to.
If it`s 'error 404' that`s good.If it`s a commercial site of some sort,that`s bad.
Use Firefox or Opera as your main browser.They are easier to keep clean
from such things.
