Choosing security software for my desktop was a confusing story for me. Being a branded user of HP I got a copy of Norton Antivirus, and that created a problem for me. In general today each and every security software bundled with antivirus + antispyware and that's why it hogs good amount of memory, so as my security software did. So, I had two option either change my security software or increase RAM. In this regard both need extra investment except free one. So, what should I do? Answer: \tStick to the same security software which I have pre-installed, \tUpgrade RAM, \tLook for some security software that is robust, cost-effective and hogs less memory, \tGo to some free one. It's up to you which option you choose. But, tweaking the software and OS gave me some bit of relaxation. Now, if you ask me a question that, which option I would choose from the above if extra investment permits my pocket\u2014 I would have answered, "Look for a security software that is robust, cost-effective and hogs less memory". Why? because \tFirst of all, I don't have to upgrade my RAM \tSecondly, robust and cost-effective that I needed to handle today's malicious attacks So, keeping the view to the selected option of robust, cost-effective and hogs less memory I searched with phrase "high-performance security software doesn't slow down PC" and got across a security software from Sunbelt Software, VIPRE an Antivirus Software. When I visited the site, the very first line of this software description depicts as, VIPRE Antivirus + Antispyware is high-performance security software that doesn't slow down your PC like older, traditional antivirus products. The claim of high-performance security software without slowing down PC is not a joke and that need to look after. So, downloading the 15 days free trial of the product can give vivid insight. Now, this is not a directive approach to use the above security software rather a finding, based on my preference and that could be your option also. At last, I will again suggest\u2014look for a security software that is robust, cost-effective and hogs less memory. Rest is your option. What is your opinion?
