Sure!
First, tell her not to worry, she most likely does not have a virus on
Linux. The first indication is that Ubuntu does *not* install a mail
server by default. That means that unless you installed one for some
reason, the likelihood of the spam actually coming from her computer
while running linux is quite low. She also does not have to worry about
any linux mail client or browser being able to execute any malicious
active-x code, etc..
Now, that being said, she may indeed have one on windows that her
antivirus program does not detect, or perhaps a trojan. Windows
frequently suffers from both of these and refuses to report on them
until they have a documented and tested fix available. In fact, quite
recently a virus scanning software vendor released malicious code in one
of their own updates.
Windows also suffers from the afore mentioned issues with arbitrarily
executable code run in web browsers and mail clients, not to mention
email address harvesting and spam sent with spoofed email "from" addresses.
I am sure that a clean windows install and a bit of security tootlage
would clear her problems up, or perhaps just get her to give up her
Windows install altogether. Update her Kubuntu install and make sure
she knows how to get into OpenOffice and that her printer works under
linux. Have her stay out of Windows and she'll find that she doesn't
have any further issues. Warn her that if, indeed, as we all suspect,
that her Windows install it at fault, her switching to windows full-time
will only ensure that her virus problems get worse and fast.
