First Clean the cache of Firefox, I am sure the website put harmful stuff inside! Also make SURE that all temp folders are empty at 100%. Temp folders are: C:\Windows\Temp C:\Users\<ACCOUNT NAME>\AppData\Local\Temp Then for your bookmarks: You will find all your application settings under your profile folder. Considering that Windows is on drive C, go at C:\Users\<ACCOUNT NAME>\AppData\ If you don't see "AppData" don't worry, the folder is hidden by default. You can either type the above address on a folder or access the folder option and set to see all hidden files and folders. Then look under: C:\Users\<ACCOUTN NAME>\AppData\Roaming\Mozilla\Firefox\Profiles\<random name>.default\ You will find a file names bookmark. This is what I do when I re-install Windows Vista. I just backup your account folder (With AppData) all together. Once I re-install Windows Vista, and then install all the drivers and software, I go to the Users folder and overwrite everything, replacing everything. There will be some file you can't replace, that is fine, just skip them. They are just some Windows special files. Once done that, all your applications will be configured just as before. Firefox will still have the bookmarks, extensions and everything. You can do this thanks to Windows Vista organized folder structure. If you don't want to go this far, then just backup/restore AppData. Another folder to backup and restore after Windows re-sintall all applications is C:\ProramData. It is a hidden folder, which contain program settings affecting all user account.
Went for a full reformat and started afresh. All is well as distinclty nippier than pre-format. Gave me a chance to get rid of some unecessary partitions too as file server in the pipeline. Thanks everyone for help partic goodbytes! Dean.
No really Like it might be that he really does have a virus because my friends USB caught a trojan Virus as well and he had to copy paste folders etc onto his computer and then reformat his USB.
I think if you have a full copy of Norton, I know the resource hogging antivirus program! However I believe that the disk is bootable and so long as its one of the most recent copies, you should be able to boot the disk and then run a deep scan.
