Works Perfectly

Had a glitch on my MBP and knew it was from downloading one of those stupid Adobe Flash updates without really examining it. Led me to buy this Virus software and through a VERY EASY and CLEAN interface, it found all 6 viruses! I checked on my Timne machine backup and it found the virus on that external harddrive too. I couldn't figure out how to delete from Time Machine so I wrote tech support and they gave me easy instructions and they were very quick to respond. I was very surprised at how fast, easy and uncomplicated this process was. My only advice for the software company is to display the entire folder link that is infectedin a display so I didn’t have to take a pic of the extended link with my camera and trace it back to infected files. Also maybe add a time frame to how long it will take to scan the external hard drive which is huge, might have given me better idea of how long it will take. Backuphard drives could take a few hours. Thanks for a great product. Clean, easy and simple.

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.
