Question about HP Computers & Internet

1 Answer

My computer seems to be infected by the Backdoor, Tidse virus. I have Norton/Symantec anti-virus. Every time I start up the computer, Symantec tells me that a restart is required. Then I restart & it happens all over again! (full message: Backdoor, Tidse?restart required ? partial, filename = NETBT.SYS, Risk type = file, Original location = C:/windows/system32/drives/, Status = infected, Action = risk was partially removed, restart required) Any ideas about what I can do to get rid of this pest? Thanks so much!

Your best bet is to reimage the machine. Even if you get rid of the virus you also get rid of the file(s) it infected. That means those files are no longer available to run and they typically are critical system files. Viruses will hide and then repopulate if you don't completely format and put a clean image on the system. Because you probably don't want to loose all of your data you will want to back it up. Here is another problem because some of that data could be infected as well. I recommend removing the hard drive and use another computer that has a good anti-virus system, backing up your data to another device. Be sure to check your email files because they can bring a virus into your system. Chasing a virus can be frustrating and ultimately unsuccessful. Bite the bullet and give yourself a clean system.

A Brief History of Norton Anti-virus


Norton anti-virus is a product of Symantec Corporation. Norton anti-virus helps you to remove viruses and malicious codes from your computer, it also protect you from online threats. Symantec programmed and launched various versions of Norton anti-virus to protect your pc and Internet Security to secure your online activities from hackers.

As per history of Norton products, it's about 25 years before Norton antivirus came on the market. The name of the first Norton anti-virus was Norton Commander, released in the year 1986, served as a standard interface for DOS. This version of Norton was invented to protect DOS from malicious programs. Norton Commander was a prototypical orthodox file manager, written by John Socha and released by Peter Norton.


Norton Commander is considered easy to use based on its constant view of two file manipulation objects at once. After starting the program the user sees two panels with file lists. Each panel can be easily configured to show information about the other panel, a directory tree, or a number of other options.


When Symantec acquired Peter Norton Computing from Peter Norton, Norton starts to develop various utilities or applications for DOS, as well as for Windows. Product activation was introduced in Norton anti-virus 2004. Spyware and adware detection and removal tool was introduced to the 2005 version. The redesign main graphical user interface and homepage hijacking protection was released with 2006 version of Norton anti-virus. With the version of 2007 windows 2000 compatibility was dropped and Vista compatibility was introduced, with anti-rootkit technology. Version 2009 and 2010 released with Sonar protection, File Insight, and rogue security software tools. The latest version of Norton anti-virus is 2011, which protect your computer being infected from facebook wall and feed.

SONAR examines the behaviour of applications to decide whether they are malicious. Various things are checked such as if the program create a desktop shortcut or create add/remove programs entry before determining the program is malicious. Another feature is Norton insight. It is a program that comes with the Norton 360. It improves the speed and quality of computer scan.

Skipping the already known files helps the scan more impact.

What is symantec antivirus??????????


Symantec/Norton AntiVirus (SAV for Windows, NAV for Mac OS X) is a virus protection program distributed by the Symantec Corporation, offering effective protection features, including infected file quarantine, online virus protection updates, and an automatic scheduler. SAV/NAV is designed to start running as soon as your computer's operating system starts. It runs in the background, checking all vulnerable files for possible infection by malevolent programs called viruses and worms. SAV/NAV does this by looking for the identifying signatures of these worms and viruses and comparing them to known viruses for which it has files. When it detects an infected file, it notifies you and manages the infection according to your preferences.

Anti-Virus paid for Norton says my Product Key is invalid


If it's expired it means you have to get a new one, most anti virus software are sold for a limited amount of time. Either way Norton is no good, I run Avast free edition and I never had any problems, you should get it too, and if you feel like having even better protection you can buy avast for life for only 65 CAD, which I bet is less than Norton.
