I took a virus and now avast is like disinstalled and I can’t install any program because Windows Xp tell me that they are not valid Win32 application…
The virus is sky something but i’m not sure because avast is down…
Also the Avast cleaning tool doesn’t work because he didn’t find any virus…
Can any one help me turning on avast or deleting the virus??
Hi,
try Avira Rescue System.
- download it to a clean system (other than your infected computer)
- launch rescuecd.exe file and place a blank CD in your writer unit
- choose your burning device from the drop down list and press burn button. Please wait until the disc is created. At the end you should see a success message
- place the rescue disc in the infected computer and boot from it.
- scan your PC
When it’s done, go to control panel and “Programs and Features”, find the old version of avast!, uninstall it, reboot the computer and then download and install latest version of avast! (Version 5) from http://www.avast.com/.
Thank’s for the help but the cd-rom of the infected PC it doesn’t work… Have you any other suggestion?
Hi 
Try this:
Have a nice day.
1 Download OTL to your Desktop
2 Double click on the OTL icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
Under the Custom Scan box paste this in:
netsvcs
%SYSTEMDRIVE%*.*
/md5start
eventlog.dll
scecli.dll
netlogon.dll
cngaudit.dll
sceclt.dll
ntelogon.dll
logevent.dll
iaStor.sys
nvstor.sys
atapi.sys
IdeChnDr.sys
viasraid.sys
AGP440.sys
vaxscsi.sys
nvatabus.sys
viamraid.sys
nvata.sys
nvgts.sys
iastorv.sys
ViPrt.sys
eNetHook.dll
ahcix86.sys
KR10N.sys
nvstor32.sys
/md5stop
c:\windows\system32*.dll /lockedfiles
c:\windows\system32\drivers*.sys /lockedfiles
%systemroot%*. /mp /s

3 Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan won’t take long.
4 When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and paste them into your reply as an attachment.
Sounds like you have fake skynet message, which is related to IS2010.
Try this,download, these two programs,Hitmanpro and Malwarebytes Antimalware. Rename hitmanpro35.exe to svchost.com.Rename mbamset up.exe to mbamsteup.com.Now transfer them onto the infected pc.You will need to use a flash pen.
Then while holding down the left ctrl key double click on the renamed svchost.com file.Hopefully this will kill the virus. You probably have no internet so HMP cannot scan, so then try to install MBAM,and run a scan with that
