I purchaed this app for my iPhone and my Windows-based laptop. After installation, it slowed the performance of both devices as to make them completely unusable. Tech support? Yeah, right. You must communicate with tech support via email. How's that for timely advice when you need it? Pricing is a scam. I have plenty more to add to this review, but no more space. Be forewarned, steer clear. T User's recommendation: Find an alternative. Do not purchase anything from TotalAV.
