As for the reliability of KASPERSKY products, I have not hesitated since I have been using them for years. However, I was a little hesitant in making a choice as I was just trying to figure out the atmosphere of Qoo10. There aren't many, but several reviews from buyers helped resolve my conflicts. Moreover, I am very satisfied after receiving the product activation information after purchase and installing it according to the instructions. Thank you seller littlewardrobe for your kind guidance. We look forward to being able to purchase again next year.
