There had been a few notorious computer viruses in the past that have caused tremendous damages not only to computers at home but computers used in business or commerce. If you own a computer, there is no need then to elaborate then how niggling it is to be attacked by such irritations. There are instances, unfortunately, wherein a computer is defenseless when a virus attacks, and it creates havoc on the machine. This havoc pertains to but not limited to slowing the computer down, deleting files, muddling registry entries for software, or even causing a total crash. If you maintain a safe back up of all the files and projects you are working on, you might not be so apprehensive. However, if you’re caught off guard with these trouble makers, it is certain that you will be in heaven and earth trying eradicate them and cursing those who have cause you such pain.
First let us know the enemy…
To differentiate virus to spyware, the source of each must be questioned. Viruses are commonly received by opening unsafe email attachments or transferring data from other computers or laptops. The use of flash drives, hard disks and CDs can be a medium for such transmission. Deleting files is the most common symptom that you may see when your PC has caught a virus. Another symptom is causing program malfunctions in your system. Even worse, some viruses can automatically initiate or attach themselves to outgoing emails to people you know or might now know. The content of the email may be malicious or some or some type of advertising.
Spyware is acquired by downloading programs or going to websites. Merely browsing or visiting a page can cause your computer its doom, especially if you are visiting “shady” websites. Another way is by downloading software from the internet. Usually free software titles that may sound too good to be true, are indeed spyware. Generally, spyware are created to spy on the user. It can record your computer activities and habits. Although usually they are not harmful to your system, but they can be harmful to you since it is invasive to your privacy.
Next, defend yourself against the enemy…
To prevent nuisances such as virus and spyware, one must install effective and up to date anti-virus software. Choose something that can scan files from your internal and external hard drives or any programs and files. Keep in the habit of making a back up copy of your files. You can store your back up to a flash drive or portable hard disk. Although these may also be prone to file corruption and physical damage, you can also use the cloud technology. Once the antivirus is installed, conduct a computer scan as often as possible and scan each portable device you plugged to your computer.
Last, cripple the enemy.
The antivirus software can notify you on the current threats, but it takes a great deal of self-control to win the fight against virus and spyware. Never open attachments from people you don’t know or even people you do know who you think do not practice safe file transfer. Stay away from the websites that have very minimal visitors. Try your best to always choose a reliable downloading website.
Should you acquire a virus or spyware despite all these suggestions, try to find out what kind of virus you have. Most viruses can be eliminated by updating your antivirus software. If that fails, visit a computer technician as soon as possible and they should be able to help get it removed.
