here's a snapshot of the events:
-downloaded smart security-
internet were messing up.
so deleted any smart security shortcuts from desktop, menu bar.
went to mozilla but couldnt get access. message: proxy server problem
managed to fix it by going to internet options and fiddled with the proxy server tick boxes and mozilla worked hurrah.
-next morning opened the laptop-
as windows were loading up, pop up messages saying cannot find file in this 'url' which i recognised as smart security.
i copied the url and pasted it in the computer's address bar and smart security came up ><
went to this forum and downloaded malware protection software. 102 items detected so i deleted them all.
next reboot, ran through avast antivirus and a thousand of virus and trojan horse alerts came up!
after moving them to chest and deleted them all, tried to go on firefox and message 'crash reporter' came up!
went to IE and it wouldnt open due to connection error(though my wireless connection works fine)
did system restore from last week, firefox still a problem but IE works.
