i actually took my laptop to some computer guru and he eventually sorted it - but I think it's because you have the same bad virus going around namely...
ok I know what it is now....
The Conficker malware outbreak has continued to spread among corporate PCs in what appears to be the biggest IT security breach in the past seven years.
Initially it was reported Conficker, or Downadup, focused on machines that weren't patched with a Microsoft emergency fix released last October (MS008-067).
However since then, the bug has evolved and is now able to spread to patched computers through portable USB drives through brute-force password-guessing, SCMagazineus.com reports.
Once in the machine, the worm can browse through the network the computer is connected to and copy itself to other machines, according to the article. This means users do not have to be at their computers or even logged on for the bug to spread.
Many experts have compared the Conficker attack to Nimda, another bug that hit corporations in 2001, which spread quickly as well. Others have speculated the bug may be the beginning stages of a new botnet.
Infected machines can potentially reveal users' personal and financial information, though it is unclear if that is the objective of the cybercriminals behind the attack. With the presidential inauguration scheduled for tomorrow, it's possible the cybercriminals may act then, since they traditionally like to coincide attacks with large events.
download this and install on your infected machine..this should fix it...
what you are going to need to do is - get to another machine download some software and load it your screwed up machine on from another machine
