You must have some type of virus/worm, I would seriously recommend backing up your system and re-formatting if you've already tried some sort of scan with a free anti-virus.

If it's a virus, then it would be something serious to do something to your boot time, which is why reformat is suggested, only do this if you have your original XP disc and serial, as you will need activation in 30 days.

(That is if you're on XP, if anything else, replace XP with your system OS).

If not a virus, it could be a faulty system, I would get that checked out at a hardware store of some sort to take a proper look at it and inform you to replace faulty hardware.

I CANT REMOVE THE VIRUS IN MY LAPTOP


If you cant remove the virus you have got, its often because your drive has been infected to a degree where qiping it for virus's is futile.
If thats the case, format your drive by booting your pc up with a windows install dvd in the drive, selecting the option to format C-drive before installing new operating system on the unit.

Most likely you Boot-section of your harddrive has been infected and therefore, everytime you boot your pc the virus loads as the first thing during start up of windows and drivers and so forth.

Tip

Different types of Virus and their effect's.


Different Types of Computer Viruses There are Different Types of Computer Viruses could be classified in (origin, techniques, types of files they infect, where they hide, the kind of damage they cause, the type of operating system or platform they attack) etc. Let us have a look at them…

Computer Virus is a kind of malicious software written intentionally to enter a computer without the user’s permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below:

fb7fa0a.jpg

Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.

Examples include: Randex, CMJ, Meve, and MrKlunky.

Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.

Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.

The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.

Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.

Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.

The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.

Examples of boot viruses include: Polyboot.B, AntiEXE.

Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.

Examples of macro viruses: Relax, Melissa.A, Bablas, O97M/Y2K.

Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.

Once infected it becomes impossible to locate the original files.

Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.

This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.

Examples include: Elkern, Marburg, Satan Bug, and Tuareg.

File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.

Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).

Some examples include: Stator, Asimov.1539, and Terrax.1069

FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.

Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.

Examples of worms include: PSWBugbear.B, Lovgate.F, Trile.C, Sobig.D, Mapson.

Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.

Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.

Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

When i turn on my laptop it ask for a password in blue and then there is a blinking curser and black screen it wont do anything after that unless i press f2 reapeatedly or f12 but i cant fix nothing on the...


There are two types of password:
1. BIOS password. To remove the BIOS password, the solution is, remove the BIOS battery. Location of the BIOS battery, the bottom of the laptop. So you have to unscrew the bottom of the laptop, find the BIOS battery and release approximately 7 seconds, then plug it back. Then, turn on the laptop, enter the BIOS by pressing F2, do the setting the date, time, etc.

2. Password Log on. When turning on the laptop, and log on, then we are asked to enter a password, but we never give password to log on. However, when we enter the password, always fails, it means the virus-infected operating system (operating system has been controlled by a virus). These cases often I meet, the Windows XP operating system is infected with the virus. The solution is to reinstall the operating system. Repair operating system, or breaking into password virus, I've tried, but always failed. So, the best solution is to reinstall the operating system.

If you are using Windows 7, you can fix with, insert the Windows operating system CD, then boot from the CD Room. Solutions you can do:

1.
Boot from CD Room, select Next - select Repair your computer - Next - select System Image Recovery

10_9_2011_8_00_22_pm.jpg

2. Boot from CD Room - select Next - select Install now - check the "I accept the license terms" - Next - select Custom (advanced). Then, select the drive where you installed windows - Next. Wait for your operating system install process to complete. Then enter your user name, etc.

After entering the desktop, don't open drive C, D, E, F, because the drive is still infected with the virus. All you have to do is, connect your laptop to the Internet, download anti-virus. You can use free anti-virus (Avira or AVG), then anti-virus updates. After the update is complete, do a virus scan, drive C, D, E, F. If a virus is detected, Primary action = repair, Secondary action = delete.


After drive C, D, E, F clean from viruses, you can open the drive C, D, E, F. You don't have to worry about losing data, because Windows 7, will backup your data in a folder Windows.old. In Windows.old folder, there are three folders: Program files, Users, Windows. Data stored in My Documents, can be found in the Users folder.

Try booting up the computer in safe mode with networking. If you can get it to boot up then see if your anti-virus scanner will run. Sometimes viruses will disable the anti-virus when they damage your computer. If your anti-virus will not run in safe mode then you will need to try and do an online scan. You can go to www.trendmicro.com and use their free online virus scanner called housecall. It is a very good scanner and should remove the virus. After the scan is complete and if a virus is removed you will need to do this step before your re-boot. Go into the control panel and find the system restore settings and disable it. This is critical because the virus can install itself into the system restore and will re-install on the computer from there if system restore is not disabled. Then reboot the computer and if it boots up without a problem run another scan with the virus scanner. Then re-enable system restore. If you are unable to boot into safemode then the windows installation is corrupted by the virus and I reccomend that you do a format and re-install of the OS. If you try and do a repair the virus will still be there when you complete the repair. Let me know if you have any other questions.

Network connection prompt error 6: handle is invalid


Hi glamredhel, Norton has removed the virus or Trojan & if you have windows system restore turned on the virus or Trojan will return once the system has re-booted. Open windows device manager & shut off system restore. Re-boot your system & re-scan your system with Norton. In your case Norton did not give you instructions on how to remove the virus. (Norton did that for you).
Once completed check windows update service for a possible update for your LAN. Asus does not have a separate LAN driver listed on Asus web site. The LAN driver is part of the chipset drivers. Remove your modem from the system & any software you installed with it. (If any). Restart your system. (If the system seems fine-good. Shut down the system & re-install your modem & any software. When completed do another windows restart. See if the modem functions (If your modem is either a cable or DSL reset it.
Shut down the system.
Located on the back of the cable modem or DSL modem you will find a tiny re-set button. Unplug the power cord from the modem. Take a pen & press the reset button for 10 seconds. Re-connect the power cord & boot the system. Check for internet connection.

The above are just a few item you should try.
Good luck glamredhel!
Post your findings.

I have a virus and stmanteec antivirus notification keeps popping up on my screen: What can I do??? Help Scan type: Auto-Protect Scan Event: Threat Found! Threat: Trojan.Zlob File: ...


If you have a virus you can not delete or if your system will not boot up correctly and you suspect a virus is the problem, a recommended solution is to start your computer in safe mode and run a virus scan. By running your computer in safe mode, non-essential processes do not start and non-core components are disabled. In other words, only the minimum necessary programs will load. Tough to remove viruses, spyware and other malware usually have no chance to run and disrupt your system and can more easily be removed.
**To run a virus scan in safe mode, you must have active anti virus software installed on your computer.
To run a virus scan in safe mode, follow these steps:
  1. If your computer is on, shut it down
  2. Power on your computer
  3. Immediately after you power on your computer, repeatedly press the [F8] key (about once per second)
  4. In the Windows Advanced Options Menu screen, use the arrows to select Safe Mode and presss [Enter]
  5. Select your current operating system and press [Enter]
  6. Select the user you would like to login under (if applicable)
  7. When your system finishes booting, click the Start button on your task bar
  8. Move your cursor over All Programs and navigate to your anti virus program
  9. Click on your antiv virus program to run it and follow the anti virus program’s normal steps to run a virus scan
  10. After the virus scan is complete, Delete all detected viruses
  11. Close out of your anti virus software
  12. Restart your computer (it should start in normal mode)
