While I cannot comment on the performance on Counterspy and other Sunbelt products, I know for a fact that Sunbelt Software is a legitimate software company. Just look at SiteAdvisor and WOT's page for Sunbelt Software and you'll see that both websites rate Sunbelt Software to be a 100% safe website (a lot of users from both websites think Sunbelt is safe as well). Hell, even Virustotal uses Sunbelt's database!
