|Chris, You host file may be damaged. Download this tool Hoster, to a floppy or cd if you have to, but to the desktop if you can.Then install it and click "restore original host".|
Next run the panda scan again and post the results.
Then download Hijack This at this link http://www.tomcoyote.org/hjt/ then place it into a folder of it's on, such as C:\HJT, so that back up copies can be made and not clutter your desktop or other folders and the backup copies of deleted items can be easily located if needed.
Once saved double click HijackThis.exe, and press "Scan". When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log, Ctrl-A to Select All, and copy its contents into the text editor.
Do not fix anything yet unless you know what you are doing. This is a powerful tool that can crash the computer if used improperly.
