Help! Can't install any anti-virus, HijackThis or Adaware
 

:$ I really hope someone can help me. My webpages (when they load at all) load extremely slowly and I'm downloading at just under 2 Kb a second.

Something has shut down my McAfee for Small business and when I contacted tech support for the computer (my brother is homeschooled) they suggested that I unistall/reinstall McAfee. When I tried to run the app an error popped up saying that the .exe file was not a valid Win32 application. I get the same message for AVG Free and Windows LiveOneCare.

I attempted to run HijackThis and I get this error msg: MSVBM60.DLL was not found

I downloaded other types (older, zipped, self-extracting) in hopes of tricking the computer, but alas, it still outsmarted me.

Ad-Aware throws an error and fails to load, Spybot SD doesn't find anything.

I tried to run Trend Micro HouseCall and it just hangs. I left it for more than an hour and it still hadn't started.

I have a LAN internet connection.

The computer is an HP running Windows XP Pro Service Pack 2. As far as I know, the automtic updates are...well, up to date.

Does anyone know what's causing this?...and even better, how to fix it. I just hate when the little nasties outsmart me.

Download ComboFix by sUBs from either of these locations:
http://download.bleepingcomputer.com/sUBs/ComboFix.exe
http://subs.geekstogo.com/ComboFix.exe

How to use Combofix:
http://www.bleepingcomputer.com/comb...o-use-combofix

You must download it to and run it from your Desktop
Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
Double click combofix.exe & follow the prompts.
When finished, it will produce a log. Please save that log to post in your next reply.
Re-enable all the programs that were disabled during the running of ComboFix..


Note:
Do not mouse-click combofix's window while it is running. That may cause it to stall.

CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

I recommend using msconfig to disable all startup items and non MS services before running ComboFix to ensure AV programs and others that interfere are disabled. A reboot is required after changes are made in msconfig.

Re: Help! Can't install any anti-virus, HijackThis or Adaware
 

Thank you so much for the help!

But, it will not let me completely download Combo fix. It takes about 40 minutes to download 1.11 mb of the 1.52 mb file. I have downloaded multiple times from both sites and get this error: Some installation files are corrupt. Please download fresh copy and retry.

And...combofix stalls right there, I have to manually end the process to remove it from the task bar.

Is there anything I can do to get around this?

Re: Help! Can't install any anti-virus, HijackThis or Adaware
 

Download Combofix on another PC and copy to desktop. You can use a flash (thumb) drive to copy the file or burn to a CD.

Have you disabled startup items and non MS services yet? That may help some.

Re: Help! Can't install any anti-virus, HijackThis or Adaware
 

In addition to running ComboFix as per willcomp's post, it sounds like you need to go to the linky below and re-install Microsoft Visual Basic run-time:

http://www.microsoft.com/downloads/d...displaylang=en

-- Also, I would recommend installing the Recovery Console before running ComboFix.

Best Luck :)

Thanks for the tips! I downloaded MS Visual Basics (I'm not sure what exactly it did/does) and I also installed Firefox (which let me download and run ComboFix and HijackThis. Here are the logs.

I don't seem to have as many problems with Firefox as I did with IE. Then again, it could just be the calm before the storm:-/ .

Thanks in advance for your help!

Re: Help! Can't install any anti-virus, HijackThis or Adaware
 

Hi Joletta,

I am pretty tied up with work, but since your original responder has not posted back yet, I though I'd jump in and say that at quick glance I do not see any obvious malware in your ComboFix log.

-- With the reinstall of M$VB runtime, you ought to be able to run the latest version of HijackThis. I haven't seen v1.97.7 in about four years.....

-- It does sound like something is cattywampus with your machine - have you done any malware cleaning recently? Any new software added or any big changes to the machine recently?

Hopefully your original responder will post back with some ideas as well.

PP :)

Re: Help! Can't install any anti-virus, HijackThis or Adaware
 

The Combofix log is clean.

Did you install VB6 runtime? It's the Visual Basic (VB) runtime module and is required for software written in VB.

why cant i install an antivirus

Is that a trick question?
