    Hi all, this is my first time posting and I thank you in advance for your help. My computer has been infected by a trojan, Win32.Lager on the file C:\WINDOWS\system32\taskdir.dll and Avast couldn't remove it.
    I followed all the instructions on the "Read and Run me first" except that I couldn't run PandaActive scan (it didn't work even when I disabled Avast protection). I am attaching the test results from Bitdefender and the HJT log. I hope I've done all this right, I'm not an expert. Can you please help me to get rid of this virus?
    Your help will be greatly appreciated

    Welcome to Majorgeeks!

    Make sure viewing of hidden files is enabled (per the tutorial).

    Please run HijackThis and click on the Open the Misc Tools Section button on the open page. Then select Open process manager on the left-hand side. Look for the following process (or processes) and one at a time kill them by selecting it and then click Kill process. Then click yes.
    C:\WINDOWS\System32\taskdir.exe

    After killing all the above processes, click Back.
    Then please click Scan and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
    R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = localhost:12080
    R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = Collegamenti
    O2 - BHO: (no name) - {259F616C-A300-44F5-B04A-ED001A26C85C} - (no file)
    O2 - BHO: (no name) - {77701e16-9bfe-4b63-a5b4-7bd156758a37} - (no file)
    O4 - HKLM\..\Run: [Microsoft Update Machine] winini.exe
    O4 - HKLM\..\Run: [Microsoft Service Loader 0.2] svshost02.com
    O4 - HKLM\..\Run: [FHPage] C:\WINDOWS\system32\shdochp.exe home
    O4 - HKCU\..\Run: [taskdir] C:\WINDOWS\System32\taskdir.exe
    O9 - Extra button: (no name) - SolidConverterPDF - (no file) (HKCU)

    After clicking Fix, exit HJT.
    Boot into safe mode and use Windows Explorer to delete
    :
    C:\WINDOWS\system32\winini.exe
    C:\WINDOWS\system32\svshost02.com
    C:\WINDOWS\system32\shdochp.exe home
    C:\WINDOWS\system32\taskdir.exe
    C:\WINDOWS\system32\taskdir.dll

    If you get an error when deleting a file. Right click on the file and check to see if the read only attribute is checked. If it is, uncheck it and try again. Other wise open Task Manager and kill the process if running then delete the file.

    Now if running Win XP goto c:\windows\Prefetch and delete all files in this folder.
    Now run Ccleaner (installed while running the READ ME FIRST)
    .

    Now we need to Reset Web Settings:
    1. If you have an Internet Explorer icon on your Desktop, goto step 2. If not, skip to step 3.
    2. Now right click on your desktop Internet Explorer icon and select Properties. Then click the Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK. Then skip step 3.
    3. If you do not have an Internet Explorer icon on your Desktop, click Start, Control Panel (for some systems it may be Start, Settings, Control Panel), Internet Options, Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK.
    Now reboot in normal mode and post a new HJT log.

    Make sure you tell me how things are working now.

    Reminder Note: Once we have determined you are malware free you will need to disable System Restore, reboot, and re-enable system restore per step 1 of the READ & RUN ME. This only applies to if using WinXP or WinMe.

    Hi and many many thanks for your help!! The Trojan is not there any more thank to your clear instructions which I followed step by step. I would have been lost without your advice so I'm happy that there are people like you who are ready to help a complete stranger like me to solve her problem! I'm not English so I fear my words can seem inadeguate to express my appreciation of your help, but I hope you'll understand the same. Major Geeks has become one of my favourite sites; it's a terrific source of information. If there is something I can make for you, please let me know!

    :) Again Grazie mille!! (thousand thanks)

    As requested I attach a new HJT log.

    Bye

    You're welcome Patrizia and your English is just fine! ;)

    Your log is clean. If you are not having any other malware problems, it is time to go back to step 1 of the READ & RUN ME to Disable System Restore which will flush your Restore Points. Then reboot and enable System Restore to create a new clean Restore Point.

    After that, you should work thru the below link. Make sure you work thru all steps and also pay attention to upgrading your Sun Java version in step 8. Your current Sun Java version is very out of date.
