Installing a good antivirus & keeping your Windows & your security software updated at all times helps protect your Windows computer from viruses and other security threats.

Now I know there is no such thing as a best anti-virus software; but nevertheless, I’d like to know which antivirus software do you use to protect your Windows PC from security threats, and why you think its the best!

Do you use a free AntiVirus software for Windows 7; or a paid one? Or do you use a fully integrated Security Suite? Do you have a second layer of defense in terms of an additional anti-spyware or anti-malware software installed?

Please do share below in the comments – which one you recommend and why!

Myself I have been a user of Bit Defender for the past 4 years in all the time using this av I have never come close to having an infected file pass into my computer, with all kinds of options and security I have found it to be the best I have ever used.
