Kernel 2.6.21.5, Slackware 12.0

Hi:
Being in a text console (VT, that is, the screen with 25 x80 chars), say tty1, I just after booting linux, I logged in as usual, typing my password. What happened just after that astonished me. In Slackware distros, a small quotation from some book is written on screen just after typing the correct password. Well, after typing my password, I could see it split into two halves instead of the quotation.

I think this clearly indicates the precese of a virus in my hard disk. Does it? Regards.

Please don't double-post. Closed.
