I very recently got a new computer. A very nice gateway with two gigs of ram and a nice hard drive. But I've started having some problems. I'm always getting messages from my anti spyware programs with messages telling me that people are trying to perform portscans. What excactly are those? And now whenever I log on there is a message telling me that cmd.exe is missing. Along with that I get another message telling me that my computer jsut recovered from a system error...I really need help figuring out whats going on. Thanks.
