REGEDIT and TASK MANAGER DISABLED BY VIRUS

Asked by: tqtclipper

I was working on a computer for the last three or four days with a nasty computer virus. I tried everyting I could locate on EE and the internet. ComboFix and a little tool I found on the systeminterval website called autorun provided the most promising help. Now a second computer on my home newtork is infected (task manager & regedit disabled on one of the three accounts only). I resisted opening a ticket to date because I was sure that I would find the answer. Currently I have two computer with the virus one it. The first computer has several registry that I can restore and gain control of the PC the second computer has a logon without admin priv and two accounts with.... the account without the admin priv is the one with the virus...

I attached the combofix file for review...

My apologies gang; but i think I need help on this one...

Hello tqtclipper,



Click Start, Run and type Command
Type the following and then press Enter after typing each one:

cd\windows
copy regedit.exe regedit.com
start regedit.com  [or regedit.com]

Navigate to and select the following key:
HKEY_CLASSES_ROOT\exefile\shell\open\command

Double-click the (Default) value in the right pane.
Delete the current value data, and then type: "%1" %* [with quotes]
(ie., quote-percent-one-quote-space-percent-asterisk.)

Exit the Registry Editor and restart Windows.


Solution 2:

Download .exe File association fix from here:
http://www.dougknox.com/xp/fileassoc/xp_exe_fix.zip
[To run the .reg files, again you will need to rename regedit.exe to regedit.com and run the REG file using "regedit.com filename.reg" parameter]

NOTE: Once set, update the definition files for your anti-virus software and scan the system for viruses.

Solution 3

From http://home.earthlink.net/~rmbox/Reticulated/4IE_Only/--ReadMe.txt

Download and right click the following file > Then select Install
http://www.google.co.uk/url?sa=U&start=1&q=http://home.earthlink.net/~rmbox/Reticulated/4IE_Only/FIX-exec.inf&e=9797

In Addition,
You can run combofix CFScript function to delete the bad files and reg entries showing in the Combofix log.
You need to turn off your monitoring programs antivirus/antispyware shield etc when running combofix so they won't interfer with combofix.

Open notepad and copy/paste the text inside the lines below into it.

Thanks Guys!! Only wish I had asked three days ago!!! My wife thinks that I am nuts working on her sister's (college student) computer that long. Anyway, I attached the CBfix logs ... Feel free to post any additional feedback. The only thing left is to figure out why I can not install XP SP2 on computer # 1 (sister's (college student) computer))... Her machine was missing about 50 hotfixes... I got them all installed but XP SP2. I get the following error msg.... Service Pack2 setup error.... the file c:\windows\system32\services.exe is open or in use by another application. Close all other applications and click retry. I tried to kill the services.exe process but could not... Any on this issue is appreciated too.

Here are the combofix logs...

It was interesting that computer 2 (my machine); the computer with the multiple logins.. I had to run  the above instructions on each login. Is that normal?

Thanks Again!!

It looks like I may have spoken too soon.

The virus returned on one of the computers. Both logs belong to the infected computer (combofix logs #2 combofix logs #1 above). Still unable to open reg or tskmgr on all three accounts. I will give safe mode a try if you can come upmwith anyother suggestions that would be appreciated as well... Also, i will search to see what else is out there for the SirCam Virus.. I will reopen the ticket... next time I will wait 24hours just to make sure i got it... One computer is still doing fine.

Thanks,
Terry

I have three logins on the infected computer. The combofix logs above are on the same computer, different logins. Right now I have control of one of the logins.. Every previous attempt to access the other two logins revelas the virus i.e.  REGEDIT and TASK MANAGER DISABLED BY VIRUS. After that I return to my good login and the virus is there again... I run combofix three or four times and its still there... the only thing that seems to work is running  my Ultimate Boot >>miniPE>>Registryt Wizard to restore the registry to a earlier restore point run combofix and then I have access to the same login again and the process repeats itself.. Oh yeah I ran hijack and cleared the errors as well as ran Smitfraudfix and BRONTGUI and just about any online scan tool that I could find.... Anyway, I will take a look at the instructions above and get back to you.

Thanks Again!!
