can't get rid of windows defender help

Downloaded it after I read someone on this forum praise it.Thought I uninstalled it with revo but I keep getting bombarded with your pc is infected .And cant stop it without shutting down computer. Will not let me make hijack log. When i type this in I'm told can't find it. please help. Now I can't open task manager to.

 

If you run SAS go into the control centre/repairs you should be able to re-enable task manager from there.

Also this may help:

Andyman, I was just about to suggest Superantispyware Its in Preferences/Repairs, on mine. The task manager fix does work. I use it sometimes.

But yeah check out the links in my profile, Frank.

this one is really good. Goto Ako's list of scanners, and the online scanners, most of them will remove malware. You are probably infected with "something".

 

Ako's list

 

Yes either way will get you there

 

Andyman whats sas?

 

SAS = SUPERAntiSpyware. A free antimalware scanner.

Thanks Andyman didn't work.

commando- Uninstalled windows defender but can't get rid of the junk it left behind.keeps interrupting me telling me all the trojans and other infections that I can clear up if I by their app.Screwed up task manger and hijack this,and jumps up and i have to shut down to rid of it. Can you help?

 

Run ReEnable it's only 64kb and usually does a good job of enabling your Task Manager, CMD, Regedit, Run, Folder options etc after malware. Once you get control over these tools, it should make things easier.

Also try manually browsing to C:\WINDOWS\system32\drivers\etc and opening HOSTS in Notepad that way instead of using the Run command.

 

thank you everyone will try all.

 

The sites in the "If you are currently infected" links should be able to get you right again. Check out some of the anti virus boot cd's that you can make yourself and scan the machine with. They might get some elements off - as they work more effectively scanning/removing whilst the operating system is off. But your best bet is running something like Comobofix (which can ONLY be downloaded from bleepingcomputer.com, and use bleeping's forum for guidance how to use Comobofix, as it is a specialist tool) Combofix and Malwarebytes + SuperAntiSpyware are really good right now for clearing rogue apps. Check out ATF Cleaner too - Clear the temp files with it.

BTW, if possible, disconnect the infected computer from accessing the internet. These rogues are continually downloading further junk. It's best to isolate it as much as possible.

Ask away if you need any help, Frank.

 

If all else fails, download ComboFix:

It should be able to clean your PC.
I can guarantee you that your PC will be free from malware.

 

Thanks fellows will try all. keep you posted.
