I am going to tell you the softwares that you must have with you. Have them with you always because once your Windows crashes, you are doomed. You are going to waste your time downloading all softwares. And this is going to cost you money in the form of data. In all, these amount to about 1500 MBs!!! Keep these in two forms: Setups Portable form None of them require you to be online (except Kaspersky or Avira or some other software while updating). The names you see seperately need to be downloaded collectively, and not all the listed softwares. DRIVERS AND PLUGINS Adobe Flash Player 18 (http://labs.adobe.com/downloads/flashplayer.html) (16.5 MB) Adobe Shockwave Player 12.1 (http://www.filehippo.com/download_shockwave) (13 MB) Java 8 Update 45 (http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html) (28.4 MB) Microsoft .NET Framework 3.5 SP1 (https://www.microsoft.com/en-in/download/details.aspx?id=25150) (231.5 MB) Microsoft .NET Framework 4.5.2 (http://www.microsoft.com/en-in/download/details.aspx?id=42642) (66.8 MB) What should you do? These need to be downloaded anyways in order to increase stability of all the softwares, and your computer. PROTECTION Check this article for totally free solution: https://hctechbyte.wordpress.com/2014/10/02/the-best-security-for-windows-for-free/ OR Kaspersky PURE 3.0 (900 INR) OR BitDefender Total Security 2014 (750 INR) What should you do? The free solution requires you to download about 270 MB of utility setups. But still leaves you with hassles to worry about. This solution is pretty secure in most cases, but if you want a sound sleep then buy Kaspersky PURE 3.0. BitDefender lags behind a bit in tackling zero-day threats. Zero-day threats are dangerous threats for which not many ways have been found by security labs to tackle, thus providing an easy way to destroy your data, and system files. Kaspersky is the best.
