With successive generations of viruses becoming nastier than their predecessors, ensuring computer virus protection through various applications is a must for every user.
An important fact that the user often disregards but must be cognizant with is that a malicious attack on a computer is not the fault of the system but often occurs due to the negligence of the user.
Therefore, the first lesson in computer virus protection entails alertness and diligence on part of the user in addition to the various forms of precautions.
Ways in which a computer could be shielded against a virus attack range from implementing simple measures like deleting anything in the mail that looks remotely suspicious to installation of firewalls and anti-virus software packages.
The user could use a combination of these eclectic methods as remaining cautious and on-guard is better option as compared to losing the sensitive data and regretting bitterly.
Basic computer virus protection entails turning off the 'auto launch' option not just in case of emails but in case of graphics as well.
This setting prevents the entry of unknown files, updates, security checks, cookies and so on without the permission of the user as these are some of the most common carriers through which viruses are transmitted.
The same rule is applicable while downloading unknown files as well as chances that many of the incoming files might have a virus embedded in them are evidently high.
Installing an anti virus protection is imperative but the user might as well be aware that this software package in itself is not infallible and needs to be strengthened and backed by a software and hardware firewall in addition to an anti spy-ware.
Lastly, the user must take time and educate himself about the mannerisms and pathways of viruses so that he is able to virtually seal his system against virulent attacks and thus ensure its longevity.
