Best Free and Safe Tools or Software for Information Security

   It would surely be a daunting task if you do not seek help of additional software to secure your computer and ensure your safety on the big bad Internet. It is fine if you are against spending more money. But, at the least install some basic tools like Antivirus. I have compiled a great list of free but reliable and effective survival tools. I personally use all of them and also recommend them to my friends. The only commercial tool i use at present is the AntiVirus "QuickHeal" (earlier i was hooked to Kaspersky--but i found it was slowing my machine a bit)  which i find very effective. After i use these tools, the free space on my harddisk increases and the computer performance also speeds up considerably.
