After using Avast for 6 years, 4 of them paid, at $30 p/yr, they could not install the renewal this year. Instead, I was told by the technical assistant who was online to help complete the failed install, that I had malware, 2000 temp files (normal was 200) and lots of background filing that had gotten into my laptop. I thought the yearly subscription was covering some of that? Wrong. System showed no scans, eventhough I had many pop-ups that scans were happening. Yes, if I did pay $170 for Total Support they could fix everything! No, thanks! I cancelled my subscription, feeling like I had wasted 4 years of paid fees and received inadequate protection.
