Yes, follow what the others have said. I got hit with it, did a complete reinstall (including a DOD wipe and a debug script) then I got it again within a few moments when the operating system connected to the internet before I installed my firewall.
What I did the second time was when the XP (or whatever) system asks if you want to connect to the internet, I hit the not-at-this-time offering. Then I install my firewall and anti-virus. If you don’t have a backup of a firewall or anti-virus the only thing I can think of, if you have XP, is to turn on the firewall that comes with the system. It’s a weaker version but it should help you.
Of course if you have already downloaded the blast removal tool you can use it then.
I just don’t llike going on the internet EVER without a firewall and anti-virus stuff. For example, I don’t know what’ s up but I am getting about 3-4 apparent viruses on my email. I don’t open attachments unless I know the sender. And these are all the brand-new variants. For me, each is 35K in size.
Hope this helps you.
