Every second there are 2.3 unique malware variations developed, so it is evidently proved that it is not possible for any premier antivirus software to detect the onslaught of latest malwares, nevertheless, it is still significant to use signature detection to keep your computer relatively risk free from the threats.
Signature antivirus companies first identify the malicious behavior of a file, then they create a program or hash file, which is a unique number that identifies the file through a string of text. Moreover, the companies evaluate the possibilities of the nature of the file and solution to render it smoothly. The developer first text the signature and update the database before applying to the system. It is not an easy task because sometimes developers need to evaluate the malicious file and treat it accordingly.
Most of the antivirus software can’t catch everything that is targeted at Windows users but still there are tricks and tips of antivirus that prevent your computer from the attack of malwares.
Two defensive steps to prevent malware attacks
The first system is to restrict Windows user that is walled against the penetration to the core of the operating system. To simply put, the defensive mechanism restricts malwares to insert or update or delete any file from the C:Windows folder. There is no full proof against any malware, but at least you can keep in much safer position to make it restricted users.
Another defensive mechanism is remaining skeptical about updates that pop up in your computer now and then. Suppose you are using an Apple app that claims to be need an update, you can trust it, but if on a Window machine, a pop up comes in, claiming that an update is needed to Flash, it is more likely an open window for malware attack. Similarly, email users need to be careful that any malware can easily be passed through a “great looking” FROM address or subject line.
Alternative methods to Windows users
If you are pretty much sure that your computer is free from malware, think again. Most of the malware are silent and invisible and it will come to effect after a long time.
CDs are safer but they are slow, so you can boot a Windows system to Linux running off a USB flash drive.You may try Chrome book (obviously this is not advertising for Google). Chrome book runs a tough version of Linux that automatically updates.For your banking and other sensitive work, use an iPad/iPhone app, and be careful of WiFi networks you are connected with.
