okay I'm on my computer right now and it's like running like shit, then I opened up Microsoft Security Essentials then it tells me that my PC is at risk that the latest virus and spyware definition needed to be updated then I tried that,while it was updating this stupid label pops up telling me "virus and spyware definitions couldn't Be updated, this application check for virus and spyware definition updates check your internet connection and try again

so is anybody familiar with the spyware Microsoft Security Essentials because that's the only spyware that I can rely on to protect my PC from nasty viruseswhich most likely I am already have viruses on my computer
