My Computer is getting SLOW....

Last month or so, I signed up for a DSL line for my home computer. Since then, my 12 yr daughter and her friends have raided my PC. I can't be sure what they were doing but ever since, my PC is getting very slow. I recall years ago, I provided a hijack this log file to a forum such as this and a very knowledgeable person was able to point out some applications that my system run slow last time. I was hoping that someone here would be able to do the same. Here is a copy of my hijackThis log file (see below)

I also have AVG installed on my system and it keeps on finding a file call C:\windows\system32\dciman32q.dll as a Trojan horse Clicker.LGW but I am unable to fix it.

thanks again in advance to anyone who is able to help me.
