Cycle Reboot

Hey, I'm new to the board so somebody show me some love!  I allowed a nasty virus into my computer which caused a cycle reboot.  I'm thinking with the cost it's going to take to fix it I should just buy a new one.  I also was checking out  Norton Internet Security 2010 and the reboot function it has for infected computers and I need to know is it worth it for me to spend the $70 for the software that may or may not solve my problem.  Talk to me Norton family!:smileyindifferent:
