Hi there. This is my real first contirbution to the tfp and i hope it answers questions that many PC newbies have.
Antivirus Software
It is essential to have antivirus software. You can get viruses and trojan horses (hidden programs that gives almost god-like power to a remote user over the internet) from e-mail, instand messengers, and from downloads. Therefore, the installation and proper use of an antivirus software is a necessity. ALWAYS remember to keep antivirus software updated.
There are lots of antivirus program out there, even free ones like
AVG.
There are also online scanners, for example
Mcafee's
Steal, trick, lie to get a virus scanner. It is a nesscecity, not another layer of protaction.
Internet Browsers
You may be reading this with Internet Explorer, maybe even Netscape. There are a lot of internet browsers on the internet that you can choose from. MS's Monopoly means that IE is the default browser for most people. However, should you like a possibly smoother or faster, bug-free experience, there are a few other options.
Mozilla - this one recieved lots of praises for its size and speed. It is a no-frills, vanilla browser with your choice of additional toppings.
Netscape - well, it's another option; but i'd go with IE anytime.
Opera - similar to mozilla (i think) i personally have no experience with this..
Instant Messengers
Lots of way for you to communicate with your friends and family.
ICQ - the world's most popular instand messenger. It literally started instant messenging.
MSN Messenger - My favourite, its reliable and has a nice clean user interface unlike the cluttered ICQ.
AOL Instand Messenger - I do not live in any area with AOL, so i dont have any experience with this
Yahoo! Messenger - a messenger by yahoo, similar to MSN.
giam - software that handles ICQ, MIRC, MSN messenger, yahoo, etc. Useful for hardcore users (credit goes to Latch - thanks!)
Trillian - similar to Giam, suggested by Pragma
File Sharing Programs
P2P file sharing networks are all the rage now. Using these, you can download files from people all over the world.
Kazaa Lite K+ - one of the more popular ones, modified version of kazaa which works the same but with lots more features and NO spyware/adware! thanks to sixate.
Edonkey - another one, same advice- spyware.
BitTorrent - new thing; you click on small files, DL them, and bittorrent starts pieceing them from users all over the net. For sites with these small "bits", try
http://www.btsites.tk/ or Supernova.org
Spy/Ad ware
a hidden software program that transmits your user information via the Internet to advertisers. Bad thing.
LAvasoft's AD-Aware - one and best choice for ad/spy ware removal.
That's all for now; i'd try and add more stuff if time permits. And i hope this posed some help to you guys.
