Being in a job that inevitably requires tons of reserach and opening random websites. I finally crashed my Google Chrome and it trapped itslef in a dealth loop every time I tried to open it. I treid everything, redownload, restart my computer, clean up my storage I mean literally everything. But my chrome still shows a warning sign says not enough space on computer, then flashes out, then trying to open itself while crashes again. I’m not sure if it’s becasue my browser is infected with virus or just I didn’t clear my cache, but there’s no other way out but trying this. I scanned my computer and used the privacy cleaner to clean both of my browsers, Safari and Google Chrome. It didn’t take long for it to complete scanning and my browser came to life! After I have suffered from four hours’ anxiety becasue I’m working from home. And I didn’t even get to the stage where I have to pay. Love this app. Saved my life.

Great Support!

I downloaded Antiirus-One and paid for the subscription to clean my mac because I was having a lot of trouble with a browser hijacker. The cleaner did find a couple suspicious things and removed them, but the hijacker was still present. I had been scouring the internet trying to figure out how to fix this and was disheartened that it was still happening. So I used the Antivirus One software to send a message to their support team. I’m pretty sure it was a matter of hours, not day, that I got an email in return laying out very simply what is probably causing the problem and how to fix it. From there it took me 30 seconds and my Mac was fixed!!! All the other softwares that I could find were promising to fix my issue for way, WAY more money. Antivirus One was super low cost and the support team responded immediately with how to fix my problem. Amazing service!

If I have issues ever again, I’ll definitely be reusing them.

Easy to download and then I had a problem...

I downloaded this softward on my Mac, after using it on my MacAir. All went well, except that I didn’t really understand each step, did I need it? Was it something extra? and what was next for me to to do. Not everyone actually gets software and knows each step autumomatically. Then, it said to restart and my screne went black, dead. I tried to restart and it would and then go black. Went to bed to get a new perspective in the morning. Now, with my Mac dead, I couldn’t get on here to ask the question or make sure of what I bought with each having names so similar.
I started it and it would not load. So I started it again holding down the shift key and it loaded. All looks good, but now my photo software will not work, it’s just dead when I try to edit a picture. And, I can hear my system running alot, everything is slower when I try go from one to another. Can someone help me with this?
