This is very nice antivirus security software . I am using this on my PC and it’s price is RS. 1299/- and it works properly. Sometimes it is happened that while you are installing some software at that time this security tells about restrictions or problems. This is very secure software and my is totally freed from any virus. One day I was installing blue stacks app, after that k7 security told me to uninstall that app otherwise there will be problem. So everytime you will be free from problem and your computer will run properly and so well. Whenever you buy it, you will get a disk and a installation ID, by using that you will get your security. It’s boosting or scanning speed is very fast and always scan all the data in my computer. So that, my computer works very well and didn’t get any type of problem with my computer. Thank you.and be cautious.
