Seems fairly fast. Interface is reasonably good. Malwarebytes' product was causing so much lag that I couldn't even access the emergency dialer or my camera promptly. Switched to this product and haven't yet had any such issue. Used Avast on the desktop years ago, and it seemed to do a good enough job detecting malware. It was slower back then, but seems to have come some way in that regard.

Excellent and friendly service! Wanted to get a refund because I had auto renewal on when the trial ended and accidentally paid for the subscription for whole year. So I contacted them through live chat and in minutes they ended up cutting me a deal. I ended up only paying 19 bucks for the service and got the rest of my money back. I could of got all my money back, but I really do enjoy using there services. Before using there services my PC was runnin slow, but now it acts great with no issues.

Generally the app is easy to use. Until recently, I hadn't had any issues. Currently when using the app, it says not connected to wifi, even though I actually am. Even turned mobile data off, but always says wifi not connected. Won't scan network, test speed, etc. Latest update is when I noticed it.
