Yesterday booted computer seemed fine, noticed Window security Essentials showed an exclamation point , showed hadn't ran it in a while. So I attempted to run it it tried to update but kept stating "no internet" but Browser accessed it fine. Couldn't understand being suspicious I tried to run Panda Online scanner downloaded installed kept crashing computer constantly had to reboot after attempting to run Panda gave up on it went to Norton Security Scan downloaded installed & attempted to run it program started tried to download update error "no internet Connection" so I started thinking virus got me somehow, then went to Micro-trend scanner it worked but found nothing. Went to Norton Power Eraser ran it nothing, ran Malware Bytes found nothing. I did get Windows Security Essentials to update manually & removed the Exclamation point it had . I guess what I'm saying do I have a virus? I have listed my System info below. Also I use a Verizon Jet pack to connect to internet. What do I do now?
