If there is a backup, it should be named "Preferences.bak" under "User Data\Default".
But generally the browser can't make this backup if the preferences file was deleted by third-party software.
Another way is syncing it back via Google account sync.
I suggest whitelisting the whole "User Data" directory in your anti-virus settings.
Those files are just text or resource files, they can't be executed even if they are infected.
