The virus or trojan will open a backdoor on target computer for the hackers so he or she will have access to the target computer. In some cases, the hackers will sell the access to another person and that person will use the access to any purpose that the he likes. If a spammer gets access to your computer, he’ll use it to send spam emails.

The DDoS attack is perform by the scammers by sending useless data to a specific web server and when the server cannot handle the data flow, it’ll crash. This is what’s happening right now to many anti-scam websites.

This is just one thing what hackers can do when our computer is not well protected. If I’m going to list what they can do to not-so-protected computers, it will be a long list. Therefore, we need to protect our computer. But, some protection come at a high price and some are free. In this article, I will tell you where you can get good optimum computer protection without paying a dime.

1. Antivirus

Your computer needs an antivirus. A good antivirus will have real-time protection, good detection rate and it’s easy to use. If you don’t have any antivirus on your PC, get one now. Antivirus can find and remove viruses and trojan from your PC. There are three antiviruses that I personally recommend. Avast! Antivirus, AVG and Avira Antivir Personal Edition.

2. Firewall

Firewall is important so you can block ingoing or outgoing traffic. If you have malicious programs on your computer, it will not be able to send out information out from your computer and firewall will be able to block it. When you’ve bought a new PC, I suggest you to activate the Windows Firewall before going online. Even though the Windows Firewall cannot protect you from some malicious threats completely, but it’s good enough to protect you before you install a new firewall. After that, you need to find a good firewall and install it in your system. I personally recommend two free firewalls. Comodo Firewall Pro and ZoneAlarm.

3. Spybot Search and Destroy

Spybot Search and Destroy is good software to find spyware, malware and adware threats inside your PC. It also has some real-time protection and best of all, it’s free. It has good detection rate and can detect keyloggers inside your computer.

4. Ad-Aware 2007

Ad-Aware 2007 Free has been used by 250 million people because it provides good protection. If you have some money to spend, consider upgrading to Ad-Aware 2007 Plus because it has real-time protection. However, the free edition is good enough if you’re tight on budget. But you need a little more work because you have to perform the scan manually and it has no real-time protection.

Such software can be used for example both in a medical clinic and in a law firm. It will equally well serve for medical billing that includes direct billing of patients, processing claims to insurance companies and many others depending on the situation and for the law firm to track time that’s billed to a certain customer. This professional billing software is capable of tracking incurred expenses by the attorney’s work also and many other things.

Billing software can manage claims made by both suppliers and customers, and in addition it can process employee time slips for example. Not only will it process them but it can also calculate automatically and process payroll deductions based on that too. In some companies they have it even easier. Employees enter their timesheets electronically and the billing software generates a calculation of their exact pay. So if you set the daily or hourly wage for an employee, the software itself keeps track of time-slips, payments, accounts and all necessary details. Of course there are online billing programs too. Such programs don’t even require software for the companies with mostly routine expenses that don’t fluctuate significantly. They do offer quick and easy to follow billing procedure though.

Billing software has just as many variations as the different factors that make up a business as it is. Having different sizes, numbers of employees, etc. or the function of the company being manufacturing, distribution or dealing with different professionals to generate business leads to a great variety in the requirements each company has for its billing software. In order to help with that situation there are free directories that match billing software with company requirements. The billing software will be a great help for you but you have to make sure that you choose the right program for your type of business and your needs exactly. That’s why it is always better to use the help of those directories, search them through and find the perfect match.
