Answer 2

I had this awesome free 14 day 100% guaranteed anti spyware anti-virus program. It went something like this. Turn computer off for 14 days, and you will get no new viruses or hacker attempts. Then turn computer back on and start using it again and notice how well the software worked during the 14 day trial.

The truth is don't skimp when it comes to anti virus and anti spyware. If you can't afford to loose the data you can afford to spend a little money to protect it. Don't think a freeware trial from a little unheard of anti virus program will have as much protection as a big name. What is your computer data worth? I would think much more then 100$ so spending money on a good anti virus, anti spyware and firewall is well spent. It is a good piece of mind and will make your internet experience much safer.

Answer 3

I like the free stuff, not trial stuff.
For antivirus, http://free.grisoft.com
For firewall, Windows firewall
for anti spyware, Windows Defender http://www.microsoft.com
and Spybot Search & Destroy, available free from http://www.majorgeeks.com
left side, click antispyware, pick it from the list.

Answer 4

there are trial versions but they only last for 30 or so days and dont have a complete protections

altho you need to be more worried about viruses than hackers

if you want a good antivirus buy Kasperski Antiviral toolkit pro

and if you want a trial version go to www.c-net.com
but i recommend not to use trials but full versions of kaspersky or norton

Answer 8

Here are the top 10 tips that can enhance your protection against hackers and viruses:

Use anti-virus software - Most viruses enter a computer hidden in a seemingly innocent program, often as an attachment to an email. Then the virus software code attached to the program produces copies of itself and inserts the copied code into other programs. A virus can result in lost data or require costly repairs to your system. You can avoid these risks by installing and using software that scans your computer and your incoming email for viruses, and then deletes them.
You can download anti-virus software from the websites of software companies or buy it in retail stores. Look for anti-virus software that recognizes current viruses, as well as older ones; that can effectively reverse the damage; and that updates automatically.

Regularly update anti-virus software - To be effective, anti-virus software must be updated routinely with antidotes to the latest "bugs" circulating through the Internet. Most commercial anti-virus software includes a feature to download updates automatically when you are on the Internet.
Install a firewall - A firewall is software or hardware designed to block hackers from accessing your computer. A properly configured firewall masks your IP address, making it tougher for hackers to locate your computer. Firewalls are designed to prevent hackers from getting into your programs and files.
A firewall is different from anti-virus protection: Anti-virus software scans your incoming communications and files for troublesome files; a firewall helps make you invisible on the Internet and blocks all communications from unauthorized sources.

Some recently-released operating system software and some hardware devices come with a built-in firewall. It may be shipped in the "off" mode. Make sure you turn it on and set it up properly. Check your on-line "Help" feature for specifics. If your operating system doesn't include a firewall, buy a separate software firewall that runs in the background while you work, or install a hardware firewall - an external device that includes firewall software. Like anti-virus software, a firewall needs to be updated regularly to be effective.

Some firewalls block outgoing information as well as incoming files. That stops hackers from planting programs - called spyware - that cause your computer to send out your personal information without your approval.

Don't fall for a fibbing email - Most viruses won't damage your computer unless you open the email attachment that includes the virus. So hackers often lie to get you to open the attachments. The email may appear to come from a friend or colleague, or it may have an appealing file name, like "Fwd: FUNNY TEXT" or "As per your request!" It could appear to link to a website or promise to clean a virus off your computer if you open it. Don't open an email attachment - even if it appears to be from a friend or coworker - unless you are expecting it or know what it contains. If you send an email with an attached file, include a text message explaining what it is.
In addition, don't forward any email warning about a new virus. It may be a hoax and could be used to spread a virus. If you receive a chain letter or hoax virus alert, let the sender know so they can stop spreading the virus.

If your computer is infected, take action immediately - If your computer has been hacked or infected by a virus, immediately unplug the phone or cable line from your machine. Then scan your entire computer with fully updated anti-virus software and update your firewall.
Before you reconnect to the Internet, think about how your computer could have been accessed and what you could have done to avoid it. Did you open an email attachment and let loose a virus? Did a hacker bypass your outdated firewall? Take steps to minimize the chances of it happening again.

Use strong passwords - Hackers may try to steal your passwords to gain access to the personal information stored on your computer. To make it tougher for them, use passwords that have at least eight characters and include numerals or symbols. Avoid common words: some hackers use programs that can try every word in the dictionary. Don't use your personal information, your login name or adjacent keys on the keyboard as passwords.
Don't share your passwords online or over the phone. Your Internet Service Provider (ISP) should never ask for your password.

Take advantage of your software's security features - Chances are your web browser and operating system software give you some options for increasing your online security. Check the "Tools" or "Options" menus for built-in security features. You probably have several choices for what types of files you want to accept from other computers. If you don't understand your choices, check them out using your "Help" function.
Similarly, your email software may give you the ability to filter certain types of messages, such as some unsolicited bulk email, or spam. But it's up to you to activate the filter.

Turn off software features that you don't use - You may want to turn "off" some software features - instant messaging, printer-sharing or file-sharing - that typically are "on" when a computer is shipped. File-sharing allows several computers (connected through a network) to use the same file at the same time. Because it facilitates the passing of information between computers, this feature is an excellent point of entry for hackers. A firewall won't block files sent to you this way. If you're not on a network, turn the file-sharing feature "off." Your operating system's "Help" feature will show you how.
Another software feature that could leave you exposed to a virus is an email preview pane that lets you view attachments automatically. The preview pane could allow a virus to be launched even if you never click on the attachment.

And if you're not using your computer for an extended period, you can turn it off or unplug it from the phone or cable line. When it's off, the computer doesn't send or receive information from the Internet and isn't vulnerable to hackers.

Back up important files - If you follow these tips, you'll reduce the chances of falling victim to a hacker or virus. But no system is completely secure. If you have important files stored on your computer, copy them onto a removable disc, and store them in a safe place.
Report serious incidents - If you think you've been hacked or infected by a virus, email a report of the incident to your Internet provider and the hacker's provider (if you can tell what it is). Often the ISP's email address is [e-mail] or [e-mail]. By doing this, you let the ISP know about the problem on their system and help them plan for the future. Include information on the incident from your firewall's log file.
