Does this mean anything to anyone?
For the past few days I get these messenges everytime I
turn on my computer. Also, after I have connected to the
internet and try to go to any website it freezes up on
me. Now I now it's not unusual for the internet to
freeze up every now and then but this has been ongoing
for like two days. I'm afraid I might have a bug or
virus or that my computer may not have fully recovered or
gotten rid of the last one. Any help or advice would be
much appriciated. Thank you.
