Quickheal is an antivirus program . it is not too good as compared to other antivirus softwares such as kaspersky and mcafee . I had downloaded the trial version of the software on my computer, but it did not work well- it worked slow, the scanning could not detect major threats and problems, updates were of no use and the condition of my laptop was pretty slow and poor but it still showed the condition-good. but still it is a antivirus program and has features such as scanning, internet protection and much more. you can download the free trial for a month but then you would have to pay to continue using the software . this software is poor and I recommend you all not download this antivirus software and download some other ones.
