Stop blaming Windows and the User
He couldn't really help it if he was browsing a pokemon and clicked some thing that looks harmless
THERE'S HOW MANY VIRUS FOR WINDOWS! if you haven't got a virus in your life ( and on windows
) theirs something wrong with you
Windows is the OS of 90% the market, no OS is flawless or bullet proof every OS has a programing language and with that you can root pc's with it ( you can hide the file system all you like but some bastard will hack it and make computing life miserable )
Windows = C/C++
Mac = Object C/C++ (?)
Linux C/C++ (?)
anyway because 90% of the world PC's are windows thats the OS the low life hackers go...
Now for the help!
If im correct most virus's live in C:\Documents and Settings\\Local Settings\Temp
Now if you are on a live cd ( im not a linux user )
you can access the file system of your c:\ drive
so delete all the things in there.
now boot in again to windows and check if that worked if not
try safe mode and well your screwed if you can get malware bytes anti malware on there and AVG and spybot search and destroy.
Don't tell him to install ubuntu its WAY different to windows! so dont go installing it think everything will work!!
If im correct you do most of your installing and uninstalling via command line...
and no ALOT of your programs wont work with ubuntu with out the need of wine...
if your not much muck around and fix person take it to a pc repair shop or something
