A while ago I downloaded a .zip file which turned out to be a virus. The virus opened all sorts of pop-ups on my computer constantly, made it freeze all the time and reset all of my personal internet settings. It took a while, but eventually after using SpySweeper, Norton Anti-Virus, Adaware, HijackThis and several other anti-virus programs, I got rid of it and all the symptoms went away. But there's still one thing that I've never been able to fix ever since I got that virus; I can't use Google. The computer I use is a laptop, and no matter what wireless signal I use, it will never load. Every other website will work fine, but the second I type in google.com it just comes up with a message saying "Unable to connect. Firefox can't establish a connection to the server at www.google.com." in Firefox and "The page cannot be displayed" in Internet Explorer. Something I did find that worked was putting in "http://18.104.22.168/"
in the address bar; someone had posted that on another forum, and when I use it I'm able to use Google, but still unable to do things like log in to my google account.
So, what can I do to be able to use google.com again on this computer?
Thanks in advance for any help,
