How to avoid Malware Attack?

Symantec a leading Antivirus and Antispyware company reported that there are more than 12000 malware detected every day. What actually malware means? Malware is a short name for malicious software they are designed to infiltrate your PC without your consent.

The best-known types of malware, viruses and worms, are known for the manner in which they spread, rather than any other particular behavior. The term computer virus is used for a program that has infected some executable software and that causes that software, when run, to spread the virus to other executable software. Viruses may also contain a payload that performs other actions, often malicious. A worm, on the other hand, is a program that actively transmits itself over a network to infect other computers. It too may carry a payload.

How do they infringe even though we have a firewall? The question is still unanswered. Is there any solution for this fatal ruthless infringement? Some would say that keep your anti-virus software updated and do a system run now and then, scan the external hardrive before using it and keep a back up of all the important information you have in your system. The saddest part is that, there are some malware that could even affect the anti-virus application.
One way to keep a check on malware is by changing the extension of the executable file of the antivirus software. But we have to make sure that the program runs with no problems what so ever. Expert technocrats suggest that one can change the extension of the executable to .com from .exe. One can also check the “hide the known extension file types” in the folder option under tools in Microsoft Windows Operating System. Although this is not the only solution to all the malware attacks one can try to keep a check on such nasty malwares.
