What happened is: I browsed some dodgy websites yesterday evening and something got corrupted with my Mac when I started this morning being at school this time - first, the time was set to 0:00 - could not connect to university VPN when I arrived, (though I used it before) I reinstalled the vpn program and it worked then. - now parallels didnt work, ( said smth about missing drivers), reinstalled parallels and now its working. - there is only a general folder that is shared between Mac OS and Windows. All that I'm using: Windows XP and after I closed XP yesterday, have chosen to revert and not to save the changes, browser used is Firefox with NoScript addon. I guess it could have gone worst, if I didnt use the protective measures I did. If anyone had similar problems, and if you have any advice. Guess I'll have to scan my Mac, but heard there is not viruses on Mac. I'm a newbie here!
