Having a computer and keeping it safe and clean is a huge responsibility. There are various kinds of computer security threats that we regularly have to deal with. Among the many hazards, computer viruses are a common source of many other problems that cause data loss, slow performance and misuse your private information.
What is a virus?
A computer virus is basically a software that gets access to your computer by attaching itself with a harmless file or program. At the first place you won’t have any idea about how harmful this program can be. Without giving a slightest hint, the virus will spread all over your system and will literally “kill” it.
Worms, Trojan horses, mail viruses and malware are some of the most common types of viruses that can infect your system.
What are the consequences?
When a virus infects your computer you will face various kinds of problems. One of the initial things these viruses do is to slow down your computer. It will take you forever to run a program or open a folder in your pc. In some cases you won’t even be able to access your important files or can lose them permanently. This can be devastating.
Some viruses like Trojan horse or malware are used by criminal hackers who try to access your computer to gain access to your credit card information, financial statements, bank account number and other personal information. So viruses don’t cause trouble by damaging your system only but can affect your career or personal security as well.
At its extreme level, a virus can completely destroy your system and shut it down.
Tips to avoid viruses
Good news is there are some real effective yet simple ways that can help you to avoid these deadly viruses. Here we will discuss about the most useful techniques to increase the protection for your computer.
1. Anti virus program or virus guard software is widely used to increase security for the computer. It helps to prevent your system from any virus attack by scanning all the incoming data and files to ensure that they are not infected.
Norton, Kaspersky, McAfee are some of the most popular and useful virus guards that can help you to increase the security of your computer.
2. If you want to ensure better protection for your system then have the hard drive and the registry checked regularly. Often it happens that a virus gets planted inside your system and you won’t know that until it strikes. And when it happens, in most cases there is little you can do about it.
So regularly virus scan your PC. Usually an effective anti virus program manages to detect these viruses before they can harm your system. Then it will notify you about the malicious program so that you can remove it from your machine.
3. Your Virus guard will have no use if it is not regularly updated. Everyday there are new types of viruses and new versions of the old ones are coming in. If your virus guard is not updated then it won’t be able to detect these new viruses.
So never ignore the notifications made by your virus guard regarding updates. You can easily find the updates for your anti virus program online that you can download to strengthen your security system.
4. E-mail is a common source of viruses. Everyday we receive loads of junk mail from different commercial sites or from strangers. Some of these mails come up with attachments. The rule is pretty much simple – never open an attachment that comes with an e-mail from strangers. This greatly reduces the chance of a virus gaining access to your PC.
Setting up ActiveX is a good way to prevent virus attacks. When the ActiveX appears in an E-mail, it actually warns you that this mail maybe carrying virus.
5. Usually malware gets access to your system through various websites and tries to gain access to your personal information. So you should avoid activating a program or downloading files from sites which are reputable, or unknown.
Always use a firewall to increase your online safety. A firewall usually helps the user to prevent virus and hackers that attempts to have access in the PC from different web sites. Google also includes a warning on search results for sites that may be dubious.
6. USB drives or floppy discs can spread virus as well. Never insert these in your PC without having them scanned to ensure they are free of viruses.
Always remember one thing regarding virus. It is easier to avoid viruses than cleaning them from your infected system (and fixing damage). So give priority to the preventive measures. It will definitely pay off.
