I am using QUICK HEAL ANTI VIRUS since 3 years. I am continuously using Internet for my general working, so need best antivirus every time in my laptop. I found this one of the best I ever seen before. They are giving offers every year on renewal of it, giving 2 months more subscription on online purchase on their site. It is able to protect in all way to our systems. It gives protection from Viruses, Malware, threats and other factors which can damage to our system. It is able to repairs our important files If any virus found in that filesl`1 It has time to time Automatic update every day. Just we have to connect with high speed internet. In case of slow network connection it is unable to update. I have not facing any problem yet since 3 years by using quick heal. They have very good customer support team. Once I have problem with updating my antivirus then I called to customer care, they resolve my complaint within 12 hours. They give me a link of downloading offline update. After installing that update my problem was solved. We can set scanning schedule into it. They have boot time scanner in which scanning started on booting. They have provided Browser protection, Email protection, Files and folder protection etc. I have one suggestion to all user of it please scan your full memory time to time to protects your pc from any damage.
