Hi

Check yous system file, do this :

hi, try this

The suspicion of possible errors in system files in Windows, it may be worth a try to run the "hidden" program that comes with just Windows.
System allows an administrator to scan all protected files to verify their versions.

If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version from the cache folder (% Systemroot% \ System32 \ Dllcache) or source files for Windows installation, and replaces the incorrect file.

System File Checker also checks and filling up the cache folder. You must be logged on as an administrator or a member of the Administrators group to run System File Checker.

If the cache folder becomes damaged or unusable, you can use the sfc / scannow, sfc / Scanonce or sfc / scan boot to repair its contents.

To use SFC:

1) Press Start
2) Select Run ...
3) Enter: sfc / scannow and press OK
(Remember that there should be space after sfc)



More info about the System
Sfc [/ Scannow] [/ Scanonce] [/ Scan Boot] [/ Revert] [/ Purgecache] [/ Cache Size = x]

? / Scannow: Scans all protected system files immediately and replaces incorrect versions with correct Microsoft versions. This command may require access to source files for Windows installation.

? / Scanonce: Scans all protected system files once when you start the computer. This command may require access to source files for Windows installation when you start the computer. SfcScan DWORD value 2 in the following registry key when you run this command:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

? / Boot Scan: Scans all protected system files every time you start your computer. This command may require access to source files for Windows installation every time you start your computer. SfcScan DWORD value of 1 in the following registry key when you run this command:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

? / Revert: Restoring default scan setting (not scan protected files when you start your computer). The default cache size is not reset when you run this command. This command is equivalent to the / Enable switch in Windows 2000.

? / Purgecache: Purges the file cache and scans all protected system files immediately. This command may require access to source files for Windows installation.

Everytime i boot up i get an error message stating that there was a boot failure and it loads in safe mode then it prompts me to buy some software to repair my netbook


Sounds like a combination of 2 things.
  1. Machine has contracted a virus.... On startup, the machine would never prompt you to buy anything unless it's infected with a virus or malware.
  2. Corrupted bootlog....Any boot failure is usually due to a corrupted bootlog. This can be for a variety of reasons ie improper shutdown, bad battery, or what I think is the case here is a virus or malware.
If possible, boot directly into safe mode (tapping F5 key while booting). From there you can try different options ie Last known good configuration, run memory test, system restore. If you can't run your anti-virus package in safe mode, you may need to attempt a system restore, preferably to a point just prior to where you picked up the virus.

I have an hp laptop which has a trojan virus and will no alow me to do anything. Do i have to pess alt F10 to start reboot as i do on my sons acer


hopefully you have an anti virus/spyware programme installed, if so keep pressing F8 on boot up to get you into safe mode, this will not allow the trojan to run.

When you get the list on screen choose safe mode, then when windows starts, choose the administrator account, go straight to my computer>properties>system restore tab, and turn off system restore.

Run your anti virus programme and then when the trojan is found and then reboot pc, then turn system restore back on.

There is trojan horse virus in my laptop. i ve a symantec norton 2004 antivirus. everytime i update my antivirus, there's some process happening n it comes again unable to hell the virus.... it got...


you need to press F8 while the pc is booting for a startup in safe mode, then when in safe mode select start windows in safe mode, go to my computer, properties>system restore tab and turn off system restore and then run the scan again as these trojans cannot be deleted when the pc is in normal use.

 

If your antivirus finds them but cannot heal, make a note of the file that has the trojan and then search for the file and delete it manually.

 

Ensure after the trojans are deleted that you tuirn system restore back on
