I like your configuration,
rohitroy1187, thanks for sharing it!
CCleaner is among my favorite tools, and we've used Avira Free AV on XP. Thumbs up for Malwarebytes Anti-malware
(do keep it updated).
A free Anti-Exploit which protects your browser & apps. (also developed by Malwarebytes) is available.
I second each of our fellow members' suggestions, and in order to learn more about our very own nico@FMA's Anti-malware scanner, read about it here:
Another safe and secure way to shield your system is through virtualization. A simple way to understand this fancy word is to imagine a raincoat that covers and keeps your clothes dry. You remove your coat, once inside again. The coat gets wet, and it's kept you dry!!
- Sandboxie Free www.sandboxie.com protects Chrome while browsing using a "sandbox".
- Toolwiz Time Freeze Free http://www.softpedia.com/get/System/System-Miscellaneous/Toolwiz-Time-Freeze.shtml protects your system from unwanted changes. If you happen to install a program with malware or infections, restarting returns your system to it's previous state!!
Each of these programs can greatly secure your computer system. I am using Sandboxie right now, and Time Freeze is installed on our old XP system.
*Remember, programs or changes you wish to keep (security update patches or Important Windows updates) must be done without these protections in place.
