Cannot find execute file!

I started playing warrock recently, and yesterday i opened up warrock, pressed start, and as i press start, a little tab comes up saying "cannot find execute file"

I think my avast virus system deleted a file that is needed for warrock to run, not sure. My operating system is vista..any solutions guys?

Also is there a way of blocking my virus system from deleting any of my warrock file, or keep warrock protected? Thanks.

the execute file is the exe, so avast probrably removed warrock.exe, i suggest reinstall and try another virusscanner DONT USE AVG its shit
I hope it works
