You just have to be ready when it comes.
That is why you will eventually need a rescue disk handy, it should contain updated software with the following functionality
- DOS access
- Mini Windows access
- UEFI support
- With wifi connection (for the antivirus updates)
- Anti Malware/Spyware
- File manager
- Partitioning Utility
- Cleaning disk/registry
Who are the main players ?
Many many rescue disks exist in the open, several of them created by Anti virus companies, several created by partitioning companies and many by computer technicians.
The first famous rescue disk (not updated since 2012) was Hiren’s boot CD, he slapped together many many applications, created a nice DOS menu and was the main rescue disk for many years.
But he stopped updating his disk years ago making it obsolete.
Ultimate boot CD, Falcon four, All in one CD and Gandalf CD are some of the better rescue CDs.
But there is a clear winner here, a community driven linux/windows rescue CD with PortableApps, Mini Windows live boot and the simple option to add secondary rescue CD ISOs really easily, as well all of the regular needed apps for this type of rescuing work.
