permissions changed

My computer is infected with virus.
It is not allowing me to install any antivirus software nor install any program.
My pc is not even going to safe mode.

i can see c:\windows\system32\installer folder and it has the rights.
i tried to remove all the temp files but few are not deleting.
i gave permissions even in registries but nothing is working out.
i even gave permissions to program files folder
when the file is being extracted in temp folder i gave access to that file in temp folder.
my antivirus services are stopped and even when i try to start i get error access is denied.

i am getting errors like Error:2755.Server returned unexpected error 1622 attempting to install package
c:\users\admin\aapdata\local\temp\vse880.msi

windows cannot find c:\users\admin\downloads\combofix.exe make sure you typed the name correctly.

Hello RisingFlight,

That certainly does not sound good.

Have you been running Combofix? Refer to this thread of the potential risk: Do not use Combofix on your own!!

As you cannot install or update any anti-virus, the solution I can give you, is to download the program onto another computer and then copy it onto a disk, to put into the infected computer.

Hello RisingFlight,

Who instructed you to run/use Combofix?

What is happening when you try to install/update security software?

Thank you,

Hi risingflight.

Vinny is off line and I will leave helping you with your problem to him but I have noticed something.

Remember you are our eyes and ears. We can only work with what you post.
We all need to get on the same page.

To help Vinny help you he will need you to answer his questions in a precise manner.

Are you able to run any of the programs he lists in post #2? Yes or No. If no explain why not.
Are you able to get to your Desktop? Yes or No. This was asked twice with no reply from you.

He asked you what is not working.
Could you in detail explain what is not working?

Another 2 questions in post #6 that are not answered.

Who instructed you to run/use Combofix?

What is happening when you try to install/update security software?
------------------

I have one question at this time for you.

Is combofix still installed on your problem computer at this time?

i downloaded as well as copied from other computer on to my local hard drive but same error.

Finally i used one tool from bleeping computers FixExec, there was one exe file continuously running

Hello RisingFlight,

Thank you for that information.

Who asked you to install ComboFix though, because I didn't mention it in my previous replies.

Are you using an administrator account or a standard user?

Please run the following FixIt from Microsoft: What happened to the Windows Installer Cleanup Utility (MSICUU2.exe)?

Thank you,
