As I said before, I have Sender blocked but today I received not one, but two invites from this damned woman at Linkedln. Karen, I suggest you tell her if she can't cure it - it is time she got a new computer and kept it free from infection. It passed the Blocked because the Sender has a few altered letters now so it can skip past Blocks.
The very least she should do is go to trendmicro.com and take advantage of the free power scan by them.
