Symantec distributes the product as a download, a box copy, and as OEM software. Norton AntiVirus and Norton Internet Security, a related product, held a 61% US retail market share for security suites as of the first half of 2007. Competitors, in terms of market share in this study, include antivirus products from CA, Trend Micro, and Kaspersky Lab.[2]
In May 1989, Symantec launched Symantec Antivirus for the Macintosh (SAM).[5] SAM 2.0, released March 1990, incorporated technology allowing users to easily update SAM to intercept and eliminate new viruses, including many that didn't exist at the time of the program's release.[6]
In August 1990 Symantec acquired Peter Norton Computing from Peter Norton.[7] Norton and his company developed various DOS utilities including the Norton Utilities, which did not include antivirus features. Symantec continued the development of acquired technologies. The technologies are marketed under the name of "Norton", with the tagline "from Symantec". Norton's crossed-arm pose, a registered U.S. trademark, was traditionally featured on Norton product packaging.[8] However, his pose was later moved to the spine of the packaging, and eventually dropped altogether.[9]
Norton Antivirus 3.0, released in September 1993, introduced a very unique feature. Unlike other antivirus software products for MS-DOS and early Windows, which will only notify you to turn off your computer, but continue anyway, Auto-Protect or the main program will scan for viruses in memory before loading themselves. If they find a virus loaded into memory, they will halt the entire computer so that you can't even perform a warm boot (Ctrl+Alt+Delete), So that you can turn off your computer from the power and turn it back on again with a clean, uninfected system disk. Most often, this can either be the rescue disk created, or the original MS-DOS system installation disk, followed by the Norton Antivirus program installation disks. This feature is the safest way to deal with any kind of virus in memory. Norton Antivirus 3.0 is also the first version for Windows 3.1.
The redesigned main graphical user interface aggregates information in a central user interface.[15] CNET reports the Norton Protection Center, while useful, attempts to advertise additional products. To further facilitate detection of zero-day malware, Bloodhound disassembles a variety of programming languages, and scans code for malicious instructions using predefined algorithms.[16] Internet Explorer homepage hijacking protection was introduced in this release as well; however notably missing is search engine hijacking protection. CNET highlighted Norton AntiVirus 2006's noticeable impact on system performance.[15]
Norton AntiVirus 2009 was released on September 8, 2008. Addressing performance issues, over 300 changes were made, with a "zero-impact" goal.[21][22]Benchmarking conducted by Passmark Software PTY LTD highlights its 47-second install time, 32 second scan time, and 5 MB memory utilization. Symantec funded the benchmark test and provided some scripts used to benchmark each participating antivirus software.[23]
The FBI confirmed the active development of Magic Lantern, a keylogger intended to obtain passwords to encrypted e-mail and other documents during criminal investigations. Magic Lantern was first reported in the media by Bob Sullivan of MSNBC on 20 November 2001 and by Ted Bridis of the Associated Press.[28][29] The FBI intends to deploy Magic Lantern in the form of an e-mail attachment. When the attachment is opened, it installs a trojan horse on the suspect's computer, which is activated when the suspect uses PGP encryption, often used to increase the security of sent email messages. When activated, the trojan will log the PGP password, which allows the FBI to decrypt user communications.[30] Symantec and other major antivirus vendors have whitelisted the Magic Lantern trojan, rendering their antivirus products, including Norton AntiVirus, incapable of detecting it. Concerns around this whitelisting include uncertainties about Magic Lantern's full surveillance potential and whether hackers could subvert it and redeploy it for purposes outside of law enforcement.[31][32]
Another incident occurred in May 2007, when Norton AntiVirus flagged components of the Pegasus email client as malicious, rendering the program corrupted.[41] Symantec customer service addressed the problem by running through a checklist of troubleshooting steps which were not always successful.
Norton AntiVirus has been criticized for refusing to uninstall completely, leaving unnecessary files behind.[44][45] Another issue is versions prior to 2009 installed LiveUpdate, which updates Norton-branded software, separately. The user must uninstall both Norton AntiVirus and the LiveUpdate component manually. The LiveUpdate component is purposely left behind to update other Norton-branded products, if present.[46] In response, Symantec developed the Norton Removal Tool (SymNRT) to remove leftover registry keys and values along with files and folders.[47] However, neither route of uninstallation will remove subscription data, preserved to prevent users from installing multiple trial copies.[citation needed]SymNRT can only remove these Norton programs:
Once SymNRT has started the removal process, it cannot be stopped. It is recommended to close all running programs prior to running SymNRT. ACT! and WinFax users are recommended to back up their databases before running SymNRT.
On March 9, 2009, some users of Norton AntiVirus 2006 and 2007 experienced a firewall warning stating a Norton-associated file, "PIFTS.exe", was trying to connect to the Internet.[49] Although this file was revealed to be a harmless diagnostic patch, the program gained attention in the media when Symantec removed posts from their forum concerning PIFTS. With no information available about the purpose of the program there was speculation that the program was malware or a backdoor.[50]
The SANS Internet Storm Center claimed to have spoken to a Symantec employee who has confirmed that "the program is theirs, part of the update process and not intended to do harm."[51] Graham Cluley, a consultant from antivirus vendor Sophos found PIFTS connected to a Symantec server, forwarding product and computer information.[52]
On March 10, Symantec made an official response to the PIFTS program, claiming posts in the support forum were deleted due to forum spam rules; however the deletion of PIFTS-related posts began before the spam attacks.[53] Symantec stated PIFTS itself was a diagnostic patch.[50] Cole stated the purpose of the update was to help determine how many customers would need to be migrated to Windows 7-compatible versions of Norton AntiVirus. PIFTS apparently was released without a digital signature to verify its identity, causing firewalls to prompt for permission when it attempted to connect to the Internet.[54]
With a Norton subscription, support is included, so you get cutting edge antivirus and security technology, plus support when you need it. You might say that with a Norton subscription, you get what you pay for, and a whole lot more.
Mac computers can get viruses and need file-based antivirus protection. Additionally, they need the other layers of protection offered in a device security software suite such as Firewall, Intrusion Prevention and Anti-phishing Protection.
Originally, antivirus scanned computer files and looked for patterns known to match computer viruses. Today, the best antivirus engines use multiple methods for identifying known and unknown online threats, and antivirus is still a foundational component of security software.
A computer, tablet or smartphone that connects to the Internet has the potential to encounter viruses and malware. While you may be careful what you do online, you could still visit a website that has been compromised with malware (without even knowing it) or download malware from a message from a trusted friend whose account was hacked. Someone else who uses your device might not be as careful as you. Having antivirus and security software for your computer or mobile device gives you protection against many types of malware that might not be easy to spot.
Installing antivirus protection on your main production computer is a good thing. Extending that protection to all your other devices is even better. With McAfee AntiVirus Plus, one subscription lets you install security software on every Windows, macOS, Android, and iOS device in your household. When all your devices are armored against attack, the whole network benefits.
McAfee gets plenty of high scores from the independent labs, though there are occasional slips. Its scores in our own hands-on tests are simply dazzling. And it goes beyond basic antivirus protection, with Ransom Guard, a simple firewall, a system to foil cryptojacking, and more.
The G Data website states that G Data released the first antivirus program in 1985. Whether or not it was the very first, G Data Antivirus has a long and storied history. Two of the four independent labs we follow give the nod to this venerable tool in their latest tests. AV-Test gives it the top possible rating, while its scores in tests by AV-Comparatives range from passing to perfect. In our hands-on malware protection and malicious download defense tests, G Data scored very near the maximum. 041b061a72
