Little by little, computer viruses are becoming more and more prevailing like an uncurable epidemy. This brings about the automatic necessity of achieving a highly localized anti-virus technology. Antivirus or anti-virus software is used to prevent, detect, and remove malware(malicious software), (a computer virus is a computer program that can copy itself and infect a computer), computer worm(malware computer program,), trojan horses(a destructive program, spyware(the ability of collecting small pieces of information about users without their knowledge) and adware(advertising-supported software). Inexperienced users may also have trouble understanding the prompts and decisions that antivirus software presents them with. In heuristic detection, success depends on achieving the right balance between false positives and false negatives.
As modern technologies develop, updating virus checkers have become an impotant activity.
Avery powerful tool enabling to overcome this kind of computer hazard is Nsauditor Network Security Auditor which is a network security and vulnerability scanner that allows auditing and monitoring network computers for possible vulnerabilities, checking network for all potential methods that a hacker might use to attack it and create a report of potential problems that were found.
Besides the above mentioned tools there are several methods which antivirus software can use to identify malware:
Another heuristic approach is File emulation where the antivirus software can determine if the program is malicious or not and then carry out the corresponding disinfection actions.
Anti-virus programs are not always effective against new viruses.
It may be very difficult to get rid of, and you can never really be sure if it's really gone or notIn such cases we normally advise to reinstall the operating system or reinstall backups. ”
Besides unnstalling antivirus software running on an individual computer there are also others including cloud-based antivirus, firewalls and on-line scanners.
1. Cloud antivirus
2. Network firewall
Network firewalls prevent unknown programs and processes from accessing the system. A firewall is designed to deal with broader system threats that come from network connections into the system and is not an alternative to a virus protection system.
3. Online scanning
Periodic online scanning is very effective for those that run antivirus applications on their computers because those applications are frequently inapt to catch threats.
4. Specialist tools
CD or USB storage device, can be used to run antivirus software outside of the installed operating system.
Finally, our review of the matter showed that an right way to manage the virus problem in organizations is a leading correct policy.
• Making sure that anti-virus software is being applied by the organization.
• How to act in case of emergency(who to contact in case of finding a virus.
• Make sure that the evil virus is eliminated.
Such measures are considered to be quite effective ans are surely apt to help users out of the awkward situation and cut the average number of incidents.
As time passes, our knowledge and experience in solving virus issue is becoming more advanced and effective.To my mind, direct user investigations and review techniques, will help us to predict and to affect the future course of computer virus trends not only within organization frames but also throughout the world.
All the above mentioned tools, methods are easily represented however getting stubborn adware and spyware off your PC can be frustrating. In any case no reason for grief, there are steps you can take to make the process easier and more effective.
