Install Anti-Virus
I can't stress this enough. A computer without Anti-Virus Protection is just plain insane. Not only do you have to install it, but you must keep it updated and scan regularly.
Paid Programs:
I use Zone Alarm Anti-Virus (Zonalarm) and I am very pleased with its performance. It, like many other anti-virus programs, checks every new file, if it from the internet, from a USB Drive, or from any other source. This is called "Real-Time Scanning", and it is very useful. Especially if you're lazy like me and don't have much time to scan!
Also, for a more "lightweight" program, try ESET NOD32 Anti-Virus (Eset) This is also a very good program, which updates itself whenever you turn your PC on.
Free Programs:
Grisoft AVG Anti-Virus (Grisoft). A good free alternative that I used before I got Zone Alarm. It is efficient, if you don't use the internet heavily. Otherwise, use a paid alternative.
Best in Test:
ZoneAlarm Anti-Virus. This program meets all expectations, and found all of the viruses that I tested it with. As the saying goes, You get what you pay for. www.ZoneAlarm.com
Install A Firewall
Why you need a Firewall:
Connecting to the Internet is like opening a door to your computer. If hackers see that door, they can easily gain access to your PC. Once inside, hackers can steal your valuable personal data, such as bank account details and passwords to many different things. Your PC can be used without your knowledge to launch attacks on other computers, even on entire networks. A hacker can even completely "kill" your computer! But, you can stop this all with a decent firewall. It is necessary to install a good firewall, keep it on, and only disable it if it is absolutely required.
Paid Programs:
ZoneAlarm Firewall: (Zonealarm). This program is one of the best out there. It "learns" your Internet Habits, and makes them secure. There is also a "free version" of this.
Comodo Firewall Pro Plus: (Comodo). I found this program to be quite restrictive. It didn't give you as much detail about the program the need access to certain things, and therefore I blocked a few things that were needed.
Free Programs:
ZoneAlarm Basic Firewall (Zonealarm). This is the "free" alternative of the other version. This is very good if you don't want to pay.
Best in Test:
ZoneAlarm Firewall. As with the Anti-Virus, ZoneAlarm takes it out. www.ZoneAlarm.com
Regularly run Anti-Adware/Anti-Spyware/Anti-Malware
Every time you visit a website, you may, without even knowing, have downloaded content onto your machine. This content includes key loggers, dialers, spying programs, advertising material, spam bots and much, much more.
Paid Programs:
SpyFerret (here). Paid programs don't give you much more than free programs when it comes to Anti-Spyware. I would recommend that you don't get paid programs, but it is YOUR choice when it comes to security.
Free Programs:
Ad-Aware 2007. (Lavasoftusa). This program performs a "deep search". This means that it checks each and every file, and "quarantines" them.
Spybot Search & Destroy (Safer-Networking). This program checks your computer for all these "nasties" and easily removes them.
Best in Test:
"Ad-Aware 2007" & "Spybot Search & Destroy". (Lavasoftusa& Safer-Networking) I give these products both the award, as they in conjunction with each other, keep your computer clean. I recommend that you run Spybot S&D after every internet session, and Ad-Aware once a week.
Have Spam & Email protection
Don't open unknown emails, don't open unknown attachments. Even if you know who it is from, do not open them if you are not expecting them.
Paid Programs:
Kaspersky Anti-Spam (Kaspersky). This program was as good as the MailWasher, but the interface was a bit harder to get around. If you would rather use a paid program, use this, or go for a free alternative.
Free Programs:
MailWasher (Mailwasher). Before you download your email into Thunderbird, Outlook, Outlook Express, etc, you run this tool, and choose all the emails that are of spam. Then, you open up your email client and download your emails. The emails that you "marked" as spam in MailWasher, are now "blacklisted" from your account.
Best in Test:
MailWasher is an excellent program, that I found got rid of my spam problem after a few weeks. I recommend this to anyone who wants to get rid of the spam in their email accounts.
5) Popup Protection:
Some pop-up's can download virus's and spyware to your machine. Get protection from them, and you won't have to deal with the consequences.
