Quick Heal is one the most renowned and trusted antivirus for PC and I think it has been very good in providing protection from internet, downloads and softwares along with external storage media.
I have been using quick heal for about 1 year and bought this for 1 PC for 1 year and got additional 6 months validity via an offer. I was using windows 7 then and the installation was a breeze. I upgraded my PC to windows 8.1 and found that quick heal has to be reinstalled after installing the new OS and it was as expected.
Recently I upgraded to Windows 10 and had some trouble initially installing quick heal since the CD provided in the box was incompatible with W10. I had to download the total security package from the official website and activate it with the key on the CD and after doing all this it was installed and had started working fine.
I use a lot of internet for browsing and downloading and I never faced any virus of malware issues It also scans the hard drives and the USB drives pretty quickly and is very efficient in anti-malware tasks.
Though quick heal comes at a slightly higher price than other anti virus softwares but it
is a lot more reliable and has a lot of advantages that make it worth the higher price tag. I would advise everyone to use quick heal as gives a complete protection to the PC.
