I am confused about Internet Security. So please guide me with utmost honesty (Please don’t fool me because I am naive about Internet Security). I am a housewife (who used to once work as a Foxpro Programmer. But later I quit the job and started taking care of my home and family). So although I am a good foxpro programmer (and not entirely naive about using a PC) I don’t know much about internet. Lately, I have started using Internet. Now, I have come to know that viruses, worms, spywares, malaware, adware, etc. can attack my personal computer even if I open my emails. In order to prevent this from happening I should have anti-virus, anti-spyware, etc. installed on my personal computer. I have also been advised to install something termed as ‘firewall’. Besides, there are so many products (McAfee Anti-Virus, Norton Anti-Virus, E-SET Safe, Trend Micro, Quick Heal, AVG, Kaspersky, etc.) And if I visit these companies’ websites I see they have multiple products that they are manufacturing. For example, I installed AVG Free for home users. But the company also sells a paid version of that Anti-virus software and also selling something termed AVG Internet Security. Similarly, McAfee sells something termed Security Center. Now, I am all confused. I have several questions:
Question #1: Which is the best Anti-Virus software currently? I am confused about which of these softwares should I buy? For example, should I buy McAfee Anti-Virus or Norton (which one is better? I don’t know and so I can’t make up my mind). Now, McAfee and Norton are just two examples. In reality, in the market place in anti-virus category itself there are several products. So an expert may tell me that I should neither buy McAfee or Norton; but instead choose Kaspersky because it is best anti-virus currenty around. So I feel you should guide me seriously about which is the best Anti-Virus software available as of now.
Question #2: What is Internet Security? For example, several of these companies have their Internet Security Softwares. Now, does that mean that if I buy Internet Security Suite of a company it will give me full protection from Viruses, Spywares, Worms, Trojans, Malaware, Adware and what not and will this Internet Security Suite also install its firewall or whether for a firewall I will have to search for another company? Which is the best Internet Security Suite/Software currently available.
Question #3: What is a firewall? What purpose does it serve? Now, my Windows Vista also has a firewall (that perhaps got installed when my PC came pre-installed with MS Vista Home Basic). Now, is this Vista firewall not enough as a protection? And which is the best firewall software currently?
Thanks & Regards,
Anita Mallya.

I know that if u click “yes it won’t fix it, it even might make it worse, so i click no, and it keeps poping up every couple minutes.
I have Spy Sweeper with Anti-Virus and NoAdware, and scanned with both 5 times, each time it found 3 viruses, i deleted them and restarted my computer, but it keeps happening, after each time i delete it and restart my computer.
Please help me get rid of it, ITS SOO Annoying!!!!!
