After countless years of using norton360 protection on windows XP and being always irked when it would absolutely kill my pc on scanning, I decided to switch to kaspersky when I finally upgraded my system.
I have been using kaspersky anti-virus for 2 years now and have been very happy with the kind of service I have been getting. I bought at a reasonable cost of 525 rupees for 3-keys, and it came with a user manual and a cd drive with the anti-virus software and, obviously, the 3 unique keys.
You can also download the software from the website which is about 200mbs in size. Upon installation, it prompts you to create an account on its website, where you have the unique key stored for future use. You can continue using the software for 365 days even if you accidentally uninstall it or format your PC.
There also seems to be no slowing down of your pc whilst scanning or updating the anti-virus. All in all, gone are the days when I’d compromise my pc security with a pirated anti-virus, Kaspersky for life!
