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.

Userinit.exe application error


Hi again:

I would suggest that you may have a virus / spyware infection that has infected this windows file.

If you can boot into SAFE Mode ( reboot the computer) and when the screen goes to the black background with white writing start pushing F8 - keep doing so until you get a screen that gives you a list of things you can do -
ie:
restart windows normally
safe mode
safe mode w/networking

use the arrow keys on the keyboard and choose to boot into safe mode.- may take a couple of minutes

once there i would suggest running virus / antispyware scans as well as running a BOOT SCAN (a type of virus scan that scans the hard drive before it gets into windows)

NOTE on running virus/spyware scans - ALWAYS QUARANTINE the file infected - DO NOT DELETE - if you delete a critical windows system file you will cause windows to completely crash and in that instance you would have to reformat the hard drive and reinstall everything.

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.

We have purchased several desktop PCs for the offfice use..\r\ntheres r lot of common issues.. 1.most of the time system gets corrupted in a sense, system get restarted over and over again without...


these xcomputers sound strongly infected. what i would reccomend being that you have alot of them for offices is to buy a copy of windows and install it on every computer, you can do this by putting the cd in and when you restart the computerhit f2 or f10 or f12 it wwill say it on the bottum of right and left corner. once u do this you are going to want to find boot menu. once u find this boot from cd and save changes and then exit. once the cd boots up you will have instrunctions right on the computer to install windows back on. make sure you partition the drives so they come completly clean. once you get the operating system installed you can go back into boot menu and select your hard drive agian. once you do this the computer should boot back up wih new os. once you get complete setp up you are going to want to see what model nic card you have that is nto being notices. and if it still isent you want to find the nodel of it and get onto internet and search that model with drivers behind it in google. once u find the drivers you can download to a flash drive and put on the computer with the nic cars thats not working.

  2. When the Windows XP Professional/Home Setup screen appears, press R to enter Recovery Console
  3. At the prompt, type sfc /scannow and press Enter
  4. Once completed, continue with the steps below
Now make sure your system is free from viruses/malware by doing the following:
  1. Remove the Windows disk and restart computer into Safe-Mode with Networking (press F5 or F8 repeatedly whilst booting)
  2. Run an online virus scan here
  3. Download, install & update Malwarebytes
  4. Run a full scan & reboot if/when asked.

Computer crashed and upon start up it states that it is missing a DLL image file and will not bring up anything


Your dell could have been attacked by a virus or malware, and it went on to replace some system files. your options are, to reinstall the operating system, my guess is you are using windows, so reinstall windows, whether xp, vista or 7, login in using service directory repair mode, that is, by pressing F8 after the dell splash screen has displayed upon powering the computer, and selecting that choice. once logged in, perform virus scan if you have a good antivirus. meanwhile copy your important files and documents to a removable drive. if the antivirus manages to clean out the virus. you can reboot in a normal mode.
the second option is to use a live cd if you have ever heard of one, boot your computer using the live cd, some common ones are hiren's boot cd, multi-boot recovery cd and any other that you might across. once logged in, copy your importnt files and documents into a removable drive and format your computer and perfom a clean installation, this time do not forget to purchase an antivirus and install, kaspersky is fairly good, for some free options, avast is a good option. then scan your removable drive and clean it for viruses before recovering your documents

You need to get some hard drive cleaner like Drive Scrubber. Wipe out your hard drive and then reload your operating system. That will take care of all the viruses..

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)

Hi masters: My computer go realy slow,when you stop using it for 10 min.I have installed a CA security anti virus,etc ,but still reporting one virus that the CA anti,hasent been able to clean so...


You need to find the path to where the virus file is located & delete it you're self. You're antivirus software should show you where it is located. Once you delete the virus file, shut down the PC. Unplug the power cord from the PC. Open you're case & remove you're memory. Wait about 15 seconds & reseat you're memory. (make sure you're memory is seated correctly).
Removing the memory clears the memory from memory virus).
Close you're case & reconnect the power cord. Boot the PC. Once windows has finished loading run windows diskClean, than run windows defrag. (may take some time). After defrag has finished restart you're PC. Run another virus scan. If you're virus software still finds a virus or you're system & its still running slow the virus may have damaged windows files or windows registry. A reinstall of windows may be needed. If you have system restore turned on than the virus is most likely being stored in one or more restore points.
Remove infected files that you cannot clean in the System Restore data archive. To completely and immediately remove any infected file or files in the data store, turn off and then turn on System Restore. To do so, follow these steps:
1. Click Start, and then click Control Panel.
2. Click Performance and Maintenance, and then double-click System.
3. Click the System Restore tab, and then click to select the Turn off System Restore for all drives check box.
4. Click OK, and then click Yes to initiate the restore point deletion.
To turn on System Restore again after the restore point deletion has completed, repeat these steps, but click to clear the Turn off System Restore for all drives check box.

Good Luck!

Mike
