Types of Antivirus Software

If your computer runs normally, it is a sign that it is working properly. If however, your computer starts to function in a way that it is far from normal, consider that as a warning sign that your computer is about to suffer from a viral attack. Computer viruses and trojans can have a serious impact on your computer such as deleting your hard drive and even taking control of your computer. With sufficient and adequate antivirus protection, you can counter the effects of an unwanted attack.
There are good free antivirus programs, however the only drawback is that it consumes a huge amount of memory. If installed on a laptop, there is a chance that this program will cause the laptop to hang. A desktop computer carries more memory than a laptop, therefore it may withstand the free antivirus software's memory consumption. This is what happened in my case. As my commercial antivirus program expired, I was left with the dilemma of protecting my computer. As I searched for a good antivirus, I finally selected one which protects against most viruses and at the same time consumes the least amount of memory. Best of all, it's free.
As compared to free antivirus programs, commercial antivirus software may be installed on a laptop or desktop without any unwanted effects. There are those programs whose software requires downloading from its main site. Paid software has some added features such as enhanced antivirus protection and firewall activation, as well as detecting unauthorized devices connecting to or attempting to connect to the protected network. Because of the nature of an open and public network, financial statements are never transacted under any circumstances. Phishing and other malicious software can find its way from a single source computer to multiple targets on a public network.
An employer who has several computers interconnected under a single network encounters certain benefits and risks regarding virus protection in the workplace. First, he must decide on whether to use free or commercial software. Employers who are constrained by budget limits aim for free antivirus software, but those who are willing to invest in a comprehensive program will get his return in the long run. Once the employer has decided on which software he will use, he has to install safety nets within each and every computer, such that every unit will access only what is authorized and no more. Employees who need to access such files by reason of their duties or functions must obtain the consent of their employer, and must take care of such files. If any important file has been ruined or the entire drive is infected with a virus through no fault of the employee, they must notify the employer immediately.
