There is something trying to infect my computer everytime I reboot?

I don't know if I should type the URL because it will probably infect your computer. The name is Win32: Renos-p [tool].

Everytime I reboot my Avast antivirus says, Malware and gives me a button to abort connection. Why is this happening?

goto start then run and type in msconfig click on startup tab at the top and it will display all the programs that start when the computer turns on. google them if they look odd and unchecked the ones you don't need.

Your PC is infected, try to clean it with AVG or Spybot S%26D

Sounds like it. Go to www.trendmicro.com and do one of their free online malware and spyware scans. It will find things that your normal antivirus won't find. Delete and remove anything it finds. Hope this helps.
