Stop spyware or virus attacks in your computer by R Martinez

Spyware attacks in your computer can ruin your computer, your financial status, steal your identity, and use your computer as a hijack system to attack other computers.

Technology has revolutionized the way we see the world. We are now able to have a conversation virtually face-to-face with someone in the other side of the world via messenger absolutely free.
Personal computers (PCs) since its introduction to the public in the mid 80s have changed our lives. Allowing the public to automate daily task, computers have become critical tools to our everyday life.
Since the birth of the internet for public usage back in the mid-late 90s, hackers have found a breeding ground. Hackers are software developers that create programs to attack computer systems.
One the most sophisticated viruses / spyware ever developed focuses on disabling antivirus programs by attacking PC's registry (PC database). Once antivirus software is disabled in a persona computer, it becomes an easy target for any attack.
Hijack programs are responsible for scanning your computer for any credit card information stored in your computer or internet browser (including credit card transactions, online banking password and ID, etc).


But, what is spyware and how dangerous is it?

Spyware (hijack programs) are automatically installed in your computer without the users' consent and many times users are deceived to allow the programs to automatically install while surfing the internet.
The source of spyware can be an email, an infected internet page, or even an infected CD that installs information into your computer.
Spyware attacks in your computer can ruin your computer, your financial status, steal your identity, and use your computer as a hijack system to attack other computers.


It's recommended to keep your antivirus upto-date and never open emails that you might not recognize, since emails with attachments are the easier way for spyware to access your computer.
What are the symptoms?

While accessing the internet do you experience?

- Slow page download
- Pop-ups
- Sudden freeze (Computer won't respond)
- Blue Screen with white letters ( known as the blue screen of death )
- Computer won't respond after you turn it on.

Any of these symptoms might indicate that your system might be hijacked and it's recommend that you take to any computer repair place (which can be very pricey). Also, not following the correct steps can endanger your personal information such as or credit cards, or online banking login information.
Also, it's recommended that you find a good program that can cure your registry.

!!THE REGISTRY IS THE MOST IMPORTANT PART OF YOUR COMPUTER!!

Good software will remove the spyware from the registry and allow your antivirus to remove the threats.

Double-sided network protection with spam filters and pen testing by Jhoana Cooper

If you're trying to protect your network from infiltrators, you might as well do it all the way. Sometimes, the harm doesn't come from outside the fences of your network. It's cause by wrong decisions made by other people who are using the computers included in your network. This is the reason why it's not enough to just install anti-virus softwares and firewalls in your network anymore. You're going to need the complementary benefits of spam filters and pen testing.

Pen testing basics

Pen testing is another term for penetration testing. It pinpoints all the factors that could necessarily harm your network from the outside. You wouldn't actually know which antivirus softwares and firewalls are actually good for you unless you know exactly what it is that you're network is at risk of. As much as possible, you shouldn't give in to mere sales talk. You should know your network's weaknesses like you would your own body. A pen testing software helps you do this, and more. It also detects new viruses which may not be in the list of the most popular anti-virus softwares in the market.

Viruses aren't the only things you need to watch out for when you're online. Your pen testing software can also help protect your system from outside computers who may be trying to hack into your delicate files. Whether you're running a company or not, this is never a good thing. When you're running a company, your competitors can simply hack into your documents when you're not protected with a pen testing software. Without this network protective system, you also run the risk of having your identity stolen from you. There are phishers all over the net, and they could try to grab your personal information for unlawful purposes under your noses if you're not careful.

Spam filters

Sometimes, the danger doesn't come from outside your network. Sometimes you let harmful elements penetrate your system because you chose to, or someone in your system did so. If you're running a network of about twenty or more computers, and you can't trust where the people navigating these computers will go once they're online, you can install spam filters which can block harmful websites from your browsers and keep your network clean and safe.

Spam filters are also useful when you're trying to protect your kids from adult content found all over the internet. You can make sure that they don't chat with strangers using IM devices without your knowledge. In terms of company networks, spam filters are also useful in conserving bandwidth within the network. Some employees like to sneak in a download or two when they're at work. This can seriously deplete the bandwidth of the entire network, not to mention cause serious damage if a virus infiltrates the system.

OS Compatibility

Whether you're choosing softwares and filtering devices that protect your network from within or without, you should make sure that the internet filter and penetration system you're choosing are compatible with the OS of your computers. To be safe, you should try to run your system on Windows and Linux versions. These two OS variations are popular with network control and protection devices.

Get Online Firewall Support from your Home by Joseph John

If you are a regular user of Internet and Web related stuff, you are required to be cautious of computer hackers 24x7. They always keep an eye over your activities and look out for ways to access your personal or financial details, or unleash a virus, worm, or spyware to destroy the functionality of your PC. All such things generate a need to have a sturdy firewall protection for your computer.

Depending on your computer needs, decide on what kind of firewall protection you will opt for. A software firewall is designed to monitor your computers activity at all times. On the other hand, if you feel comfortable installing and configuring hardware, then you can consider a hardware firewall in the form of a Cable/DSL router.

Once you upload a firewall program in your computer, you will be sure of your computer security. However, all firewall products have their own limits. Most firewalls will not scan your PC for viruses that can harm your system. Likewise, there are not any hardware firewalls on the market that offer virus protection. This clearly means that your PC is still vulnerable to virus attacks.

The best solution to fight against computer viruses is installing an anti-virus software program. You can either buy a separate anti-virus program or shop around for a software firewall with anti-virus protection built-in.

In case you are bit confused about these computer security products, you can consult with computer support technicians. They will help you with everything starting from choosing the best firewall protection or antivirus to firewall installation and configuration. You don't need to worry about anything with computer support resources.

Apart from such services, these online computer viruses technicians can even help you with following services:

IPv6 and the Ultimate Cyberattack by stickystebee

The new internet protocol IPv6 will vastly increase the number of internet addresses available. Whilst IPv4 allows around 4 billion addresses, IPv6 increases this to around 3.4x1038. A major motivation for additional address space, apart from the fact that most of the currently available addresses are already allocated, is that it is foreseen that in the near future the will be an explosion in the number of devices that directly access the internet, each of which will have its own unique IP address.

Some obvious examples are mobile phones and cars. Already many mobile phones are used to access the internet via their network provider but currently the connection to the internet is via a system that is similar to Native Address Translation (NAT), which has a considerable number problems. Neither will it be long before all new cars have an IP address and are permanently connected to the internet. Self organising sensor networks will become commonplace and used for such diverse activities as monitoring the environment to public health care. Each node of this network will require an IP address. Items marked with RFID tags (Radio Frequency Identification) will also require IP addresses so that they can be monitored and organised.

In the home the television and the refrigerator will have IP addresses, as will the central heating system and your lighting circuits, intruder alarms, door lock and even your curtains. The internet will become ubiquitous and the connectivity will be almost infinite.

This of course created a massive vulnerability the cyberattack; so much so that the US government is investing $30 million into countermeasures against such a perceived attack. One of their concerns is hardware viruses that could be incorporated into chips. This could then be activated over the internet and used to launch massive coordinated cyberattacks from such items as televisions and refrigerators. This might sound like science fiction but the American Defence Department is taking it very seriously. Effectively they are carrying out research into the ultimate antivirus software in order to protect the integrity of tomorrow's internet.
