Norton Support Phone Number

Norton anti-virus software is best software used to prevent, detect and remove malware computer viruses, malicious root kits, BHOs, ransomware, worms, hijackers, Trojan horses, keyloggers, backdoors, malicious LSPs, dialers, fraudtools, adware and spyware.Norton Phone Number This page discusses the software used for the prevention and removal of malware threats, rather than computer security implemented by software methods. Computer security, including protection from social engineering techniques, is commonly offered in products and services of antivirus software companies.

Signature-based detection involves searching for known patterns of data within executable code. However, it is possible for a computer to be infected with new malware for which no signature is yet known. A variety of strategies are typically employed.Norton Technical Support To counter such so-called zero-day threats, heuristics can be used. Some antivirus software can also predict what a file will do by running it in a sandbox and analyzing what it does to see if it performs any malicious actions. One type of heuristic approach, generic signatures, can identify new viruses or variants of existing viruses by looking for known malicious code, or slight variations of such code, in files.

 An incorrect decision may lead to a security breach. No matter how useful antivirus software can be, it can sometimes have drawbacks. Antivirus software can impair a computer's performance. Inexperienced users may also have problems understanding the prompts and decisions that antivirus software presents them with. If the antivirus software employs heuristic detection, success depends on achieving the right balance between false positives and false negatives. False positives can be as destructive as false negatives.

Real-time protection

This monitors computer systems for suspicious activity such as computer viruses, spyware, adware, and other malicious objects in 'real-time', in other words while data loaded into the computer's active memory: when inserting a CD, opening an email, or browsing the web, or when a file already on the computer is opened or executed. Real-time protection, Real-time Scanning off, access scanning, background guard, resident shield, auto protect, and other synonyms refer to the automatic protection provided by most Norton antivirus, anti-spyware, and other anti-malware programs.

Antivirus Programme

Anti-virus programs are not always effective against new viruses, even those that use non-signature-based methods that should detect new viruses. The reason for this is that the virus designers test their new viruses on the major anti-virus applications to make sure that they are not detected before releasing them into the wild. Detecting adware and spyware is a major challenge for anti-virus programs. Adware and spyware have full administrative access to the computer and are invisible to users and hidden from the list of running processes in the task .manager. Root kits can modify the inner workings of the operating system and tamper with antivirus programs.
