For past few days my laptop got quite a few malwares / virus. I somehow got it cleaned using few free anti-virus softwares / with the help of various articles in the Internet.
During the course of research!!! I stumbled upon a very interesting article on how to make use of your HOST file to protect your machine. Check out http://www.mvps.org/winhelp2002/hosts.htm
This Host file for Windows, has entries to block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and even most web browser hijackers. This is accomplished by blocking the internet connection to malware sites.
But one thing which I have noticed as of now is my laptop has become slightly slower after replacing my old HOST file with the new file given in that site.
I opened the HOST file and OMG there are hundreds of malware/ad related website listed there. I am not sure how they managed to collect all these address :)
