A number of people believe that it is not recommended to have anti spyware and virus protection installed in the system unless you are a frequent downloader. The truth however is very different from that. When you enter a website, your system automatically downloads a lot of data from the website and if any website was infected with virus it is very easy for that virus to enter your system.
Considering how dependent people are today on the Internet you would probably visit a lot of websites that you have never visited before. There is no telling whether or not a website is infected with a virus unless you are on the inside and once you have visited the site the virus could enter your system within a matter of seconds if there is no antivirus present. An anti-virus acts as a wall between the virus and your system and ensures that the virus does not enter your system.
An antivirus is an affordable and effective way to keep a virus or a Trojan out of your system. People spend lot of money on their computers or mobile phones and a virus could easily destroy the health of your system in no time which is why investing in a good quality antivirus is important. When you have an antivirus installed, you never need to worry about downloading a file or visiting a website because the anti-virus protects your system. It will run regular scans to ensure that no files on the system are infected and in case any file is infected it automatically deletes it before it could cause any problems to the system. If you are not too sure how to choose the right anti-virus make sure you go online and read reviews about the various antivirus options available in the market for you to download.
