Computer has deleted all programs and will not install or download anything new

Hi there, I was wondering if anyone could help me.

I got a virus whilst trying to update my virus software and my now my computer won't let me install or download anything including virus software.

I have download the Hijackthis software and received and saved a log. I have read on some forums the next step is to download the CombiFix tool bit my computer will not allow me to use this.

The log Highjackthis found is:
