@ Computer Works we have become very good at virus removal, most of the time we are able to remove the virus, spyware or infection without data loss or having to wipe and reload your system.
But in the event that your system needs wiped and reloaded we have the knowhow to save your data.
In rare cases some data may be lost due to infection with no removal tools available, The only remedy in this instance would be deletion or quarantine till an appropriate solution can be found.
