Viruses are programs that get into your computer environment without your knowledge and then use your computer to connect to other computers and install a copy of themselves in those computers adn thereby spread. Virus programs are usually not content to just spread. After replicating, a virus program may do a silly prank, harm to your computer by corrupting files or even destroy its ability to serve you. Virus programs may also give a hacker a back door into you computer and thereby allow the hacker to use your computer to clog other sites or to steal your identity. If you think you have one disconnect from the web immmediately and remove it with anti virus pattern recognition tools. Avoid the free ones. Use a major product that large companies depend on. An anti virus program can be a virus itself.

What should i do to my digicam affected with trojan virus?


1. Transfer files to your computer that you don't want deleted.
2. On your camera, select "Menu." Go to "Set Up," and choose "Format."
3. Choose "Memory Card" and authorize the Reformat. This will clear everything off of your memory card.
4. Connect your camera to your computer with a USB cord, taking note of what drive it creates. It should be the E: drive, but each computer is different.
5. Download a free anti-virus program such as Avast! or AVG, or open you computer's default anti-virus software.
6. Choose a drive scan. Select the drive that your camera is in, and then initiate the scan. The anti-virus software will identify if there are any viruses left on the camera.
7. If there are no viruses found, you were able to delete them while reformatting the memory card, and you are done. If the anti-virus software finds a virus, move it to quarantine and delete it.
8.Run the anti-virus software a final time to double check that the camera is free of viruses.

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.

What are the viruses


A computer virus is a software program, script, or macro designed to infect, destroy, modify, or cause other problems with your computer or software programs. The user may protect him by using an anti-virus protection program. The anti-virus protection program designed to detect, protect, and clean any computer viruses. This is the most basic way to define a computer virus. There are tens of thousands of viruses out there with many more created on a daily basis. The protection program needs to updating on a constant basis. The computer needs updated with its running system, email and files in order to keep a completely safe PC. The normal use of any computer still puts the system at risk of being compromised by hackers unless you provide an anti-virus program for your protection along with a personal firewall.

hope this helps

Hi my computer has a bad virus that i cant get rid of. ive tried a lot of programs but my computer is still the same.


ave you done a full virus scan with up-to-date anti-virus software?

If you don't have any anti-virus software and you use the Internet, you REALLY need to get some! My preferred anti-virus package is Norton Anti-Virus but, if you want a free copy in a hurry, download AVG Anti-Virus from www.grisoft.com - that's also excellent smile.gif

How to speed up computers.


**1The main reason which slowdowns system is VIRUS ATTACK.
Powerful tool to avoid this is installing Anti Virus.
Anyhow installing a anti virus is not sufficient.You need update the anti virus continuously(once for a week)
Updating means:-Hackers will generate the viruses and they will upload those viruses to internet data base every day.Which enters our computer when connected internet.The companies which provides the anti virus software will scans those viruses and they update those virus name our anti virus data base so that if any programs by those virus names which are in anti virus data base.Anti virus will block those programs.
So It's necessary to update the anti virus program continuously.

If you have genuine Windows operating system you can use "Microsoft Security Essentials" for FREE.



**2The reason which slowdowns PC is creation of unwanted sectors in hard disc.


For this Defragmentation is the best method to clear unwanted sectorsTo defragment the hard disc Select the partition>Right click>Properties>Tools>Defragment disk>Defragment>ok
Watch this...

**3)Another aspect which slow downs the system is creation of error sectors
you can use Check Now option to clear error sectorTo activate Check Now*Select the partition>Right click>Properties>Tools>check nowIt check for error during next reboot


**You can use "CHKDSK" command in DOS(instant check)


**3)You can use Disk Cleanup to delete temporary files,offline pages,log files, queued and error reports(These files are not important and files consumes much memory which can't cleared by us so we need to use Disk Cleanup.
To use this thisSelect the partition>Right click>Properties>select Disk

Cleanup (Disk Cleanup can be used for C: drive only effectively(Because temporary files,offline pages,log files, queued and error reports are saved in C: only)


**Options and Menu's are with respect to Windows7 & Windows related operating systems.

Thank you have a nice day

Currently i am using administrativerights iwant to use userrights


As i am not completly aware about the error message that you are receiveing i will ask to uninstall the avira antivirus personal if u have a cd or product key with you and then delete the user account by keeping all files create new user account give it full permission and reinstall the software.
But in some circumnstance it could also be that you have more that one anti virus in the computer as hp computers come with Norton that can create conflict if it is expired so need to check that and uninstall any antivirus that is present make sure you only have one anti virus.

Best of luck

About sound manager


It's probably some sort of virus. There's been no known existence in any system that creates .exe while moving or copying files unless its a virus loaded in memory monitoring file access. Virus is made to proliferate. Don't try to execute the .exe file and immediately scan your computers both desktop and mobile for possible additional existence of viruses by using dependable anti-virus software with latest updates - the anti-virus software will not be able to detect it if it's not on its latest virus database list & signatures.
