Question about PC Laptops

2 Answers

Laptop screen Hi. My laptop was infected by a Worm.Win32.NetSky virus (ya gotta love grandkids). My Norton 360 did not detect the virus. I tried to load BullGuard, but I couldn't uninstall my Norton, and I was afraid of a conflict between the two, so I didn't load the BullGuard. I decided to use my recovery disk, wipe the slate clean and start all over with the original factory settings. When I did this and rebooted, the screen came back so dark I can't see anything hardly. I did have to replace my screen last year and I have also added more memory to my computer. My computer is pretty old. It is a, but has been a great computer. Do you have any suggestions? I appreciate any help you can give me. Thank you so much.

Try turning the brightness up. You can usually do this by holding down the blue "Fn" key, and then hitting the key (usually the F8 or 8 key) with the blue "brighter sun" on it.

    One thing I just thought of - you say your laptop is pretty old? Some of the older laptops had a brightness adjustment roller on the side of the screen itself. Could this be the case for your laptop's screen?

Malware


Hi.

This is quite a severe virus. Download Microsoft Security Essentials from the link below and install & run it, see if it gets rid of the malware.

Its not a good idea to plug in any flash or external drives to your PC until you have removed the virus as you will infect them too.



Regards.

How Norton Antivirus Works


Norton has traditional virus detection method like Signature base and Heuristics base detection, with anti-virus, anti-rootkit, anti-malware, anti-spyware etc. Symantec upgrade and releases new and more improved features with its every release. Signature based detection includes searching for knowing structure within executable code, however your computer can be infected with most new virus which signature is not known. In that case heuristics method can be use it can identify new viruses by variation of such code, in files. Malwares are very difficult to detect even for the most new anti-virus software. If you are using Norton Antivirus, you should update its data-base and virus definition every day, so that when you scan your computer, it can detect all possible threats. Some new features like SONAR, it 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.

Norton insight is a program that comes with the Norton 360. It improves the speed and quality of computer scan. It identifies well known files of client machine and excludes them from constant monitoring and scanning. It only scans unknown and unsecured files. Skipping the already known files helps the scan more impact.

Norton 360 introduced a very effective tool - Norton Power Eraser, it removes threats which standard anti-virus may miss. It cleans up system where malware prevents anti-virus installation. Apart from these, the key technologies of Norton anti-virus software are anti-virus, anti-spyware, anti-rootkit, and pulse-update - provides up-to-the-minute updates that protect against the latest threats without slowing down your computer, firewall software - that can use for mapping and monitoring network.

Apparantley i have a trojan worm in my lap top, i have norton and caled them they say i have a problem and my laptop is out of warranty and i have to purchase another one is this true


NO, you do NOT have to purchase a new laptop.

What the people at Norton probably meant was that your Norton anti virus software has expired and you need to purchase a new anti virus subscription from Norton if you want them to help you.

There are however other anti virus software manufacturers out there that are free and/or will allow you a 30 day trial period.

To help you clean out the worm in your system:

  • Find out the name of the worm you have on your system (your norton program will tell you this).
  • Go to this page: http://free.avg.com/us-en/virus-removal
  • Click on the link that has the same name as the worm on your system (don't worry about the I-worm or W32 part of the name, e.g. if your worm name contains navidad you want to click the I-worm/navidad link or if your worm name contains bugbear you want to click the I-worm/Bugbear.C link etc.)
  • Follow the instructions on the page you get to in order to get rid of your problem.
Hope this helps ;)

Laptop infected with worm.


Nortons sucks. you should try an anti-virus scan with Malwarebytes, then you should install Avast as your resident protection. 

Be sure, when uninstalling Nortons, to use the uninstallation tool found on the nortons site. if you use the regular windows uninstaller, it will not remove all of it, and it will slow your computer down.

Laptop infected with worm? Help


No virus checker catches them all, and frankly, Norton 360 is pretty weak. Try running AVG, which is downloadable and free.

How can i remove virus worm/autoit permanently


its simple guys..!!!
if it asks for permission to access outlook..don't permit it because it is a smart virus and is going to spread it to all the people on your contact list...!!!
simply open task manager and end process tree of KHATRA.exe , gHost.exe , xplorer.exe and OUTLOOK.exe seperately...!!
then run your anti virus or download one if you don't have one..!!!
run a complete computer scan in detail..!!
then delete all files which are infected by the virus because the results contain only duplicate files which are created by the virus
