screwed up

well, it all started today at about 2:30 when I got out of class and I was checking my email, I got this email from a U of W tech person saying something about port 445, or in other words me downloading crap while at school. There was a link on the email for a free anti-virus program, so I downloaded it. This was a huge mistake, in the end it was just a huge pack of spyware, through multiple checks the maximum was like 289 pieces of spyware. It took like 2 hours to get rid of it all. That is my story of adware for the day...
