How often do you end up having to reformat a computer due to the
multitudes of spyware accumilated on the computer?
Depends on the level of infection. If you have 1 or 2 infections that
can be eradicated in under a couple hours of effort, that's the way to
go. If you get stuck having to clean up someone's host that has 95
infections whether viruses, spyware, or other malware, it could take
longer to sterilize the host than to backup the data files, reformat,
reinstall the OS and apps, and restore the data. Using drive images can
be even faster for disaster recovery. It takes me about 4 to 6 hours to
reinstall a fresh copy of the OS, all applications (I have lots of
them), restore data, and edit all OS and app configurations or tweaks.
If I spend more than half that time on sterilizing a host (which may
still leave you in not-as-stable-as-before a state) then I'd rather wipe
and reinstall. Restoring from a drive image takes about half an hour
but you lose everything you've installed since then (and your data
created or modified since then if you didn't do backups). After working
on a host for 4 hours, wiping and reinstalling starts to look attractive
and restoring a drive image even more so. Luckily, me and my fellow
tech and pros at work rarely get infected. Usually it is some friend's
home PC or someone off in Training, Sales, or Marketing that wastes your
time (and usually they have so many infections that it isn't worth the
effort to sterilize so instead just get their data and wipe &
reinstall).
