So what is going on with Hotmail, anyway???

So, tonight, my email is totally screwed....normal email from friend "looks like spam"  or "suspicious email" and I can't respond.....then I'm prompted to download something to "fix the problem" and surprise!! They try to sell me a program.....who can't see through this??  My email was blocked, finally unblocked, but a lot of hassle getting back in when there was no problem with the email in the first place.  This is getting to be too much of a problem to deal with.  Can't forward a message if it has pictures in it.  Why all these problems all of a sudden??  My computer is sufficiently protected, and I don't need to buy your clean up program!
