Antivirus which is a virus

Simply complete your purchase and the download link will appear on the order confirmation page. The same download link will also be sent to you in an order confirmation email. Please note, you will need your activation code to use your security application. This code will be displayed on your order confirmation page, as well as emailed to you.

When purchasing your license, simply select how many Windows PCs you want to protect. During your license period, you can protect any number of Windows up to the total number that your license covers.

For example, you could select a 3-PC license to protect up to three different desktops or laptops used in your family. Yes, you will get the latest version of the software and all upgrades subsequently released during your subscription term. Disadvantages: Although these are huge benefits to heuristic virus checking, the technology today is not sufficient.

Virus writers can easily write viruses that don't obey the rules, making the current set of virus detection rules obsolete. Changes to these rules must be downloaded, and thus these virus checkers must be updated and won't stop many new viruses, which gives them similar characteristics to scanners.

In addition, the potential for false alarms and not detecting a known virus is greater with heuristic checkers than with scanners. Interception Definition: Interception software detects virus-like behavior and warns the user about it.

How to detect virus-like behavior? Use heuristics again. Many viruses will perform some suspicious action, like relocating themselves in memory and installing themselves as resident programs. Many software packages have this as an option, although most people usually disable it.

Advantages: Interception is a good generic method to stop logic bombs and Trojan horses. Logic bombs will trigger a usually destructive sequence given an event, such as the date being set to a certain date. When not detected by scanners, interception software will usually detect the destructive and unusual sequences of events caused by logic bombs and Trojan horses. Disadvantages: Unfortunately, interceptors aren't very good at detecting anything else.

Interceptors also have all the drawbacks of heuristic systems - difficulty differentiating virus from non-virus, and easy to program around. Also, most interceptors are very easy to disable, and so many viruses frequently disable them before launching. Due to the nature of an interceptor, this software is unable to detect viruses before they launch, and a lot of damage could already have been done.

Combined with their limited usefulness, most software packages disable or strongly limit interception by default. A sample is automatically uploaded to an analysis center when the system detects virus-like activity. If the virus matches a known virus, then a vaccine is downloaded to the infected computer and the software cleans it out.

If this is a new virus, the sample is sent to analysts to develop a vaccine. This greatly speeds up the time it takes to clean a virus off of a computer, thus greatly decreasing the ability the virus has to infect other computers. Unfortunately, virus activity is detected using heuristics, which, as mentioned above, are not totally accurate.

Network Associates has a similar process in its VirusScan software. Unfortunately, not many other improvements to virus software are foreseen, and improvements in this area rely wholly on improved AI to detect viruses. Ways to Defeat Anti-virus Software Top Because the same anti-virus software methods are in use all over the world, virus writers have attempted to defeat the software in their viruses, either by disabling the software or getting around the detection algorithms.

This section will briefly examine the techniques that virus writers use to get around the software and how effective they are in doing so. Polymorphic viruses attempt to neutralize virus-scanning techniques by changing the code every time the virus infects a new computer. Even if the virus signature remains unchanged, the checksum of the virus will, ensuring that anti-virus software won't pick it up. Fortunately, there are a number of excellent products on the market today to choose from.

Antivirus software begins operating by checking your computer programs and files against a database of known types of malware. Since new viruses are constantly created and distributed by hackers, it will also scan computers for the possibility of new or unknown type of malware threats. Typically, most programs will use three different detection devices: specific detection, which identifies known malware; generic detection, which looks for known parts or types of malware or patterns that are related by a common codebase; and heuristic detection, which scans for unknown viruses by identifying known suspicious file structures.

With so many internet-connected devices in the home today, technology has made everyday living more convenient—but also riskier. Get protected. Don't have Fios yet? Check availability.
