How can I remove a virus when I can't get my antivirus to work? I am open to any and all suggestions. I will provide what ever information is necessary to rectify the problem and I am willing to paypal a reward to whoever solves the issue.

Well you could try booting in safe mode. (Press F8 during startup to bring up boot options.)

Also, it would be much more helpful if you gave more description of exactly what is happening.

I've tried safe mode, but it errors. And chiefcrowe, it won't allow me to got to that site. That is the main thing it is blocking all security sites.

If possible, use a clean computer to go to that site and get the download.

You may also be able to make some headway by doing a System Restore to go back in time to before the infection happened. Start > All Programs > Accessories > System Tools > System Restore. Any good? :confused:

Try using this URL to reach Avira's site like Chiefcrowe suggested:

http://62.146.210.133/en/support/support_downloads.html

If that works,

1) go ahead and back up your files, email, contacts, music, videos and whatever else you value,

2) ensure that you have your Windows CD or DVD and your license key, just in case you blow stuff up

3) then download and run Avira AntiVir Rescue System. It should create a bootable CD.

4) Boot the system from the CD and have it scan.

It blocks me from all security websites.

Even by IP address? Did you try?

Anyhow, open Notepad, and use it to view C:\Windows\System32\Drivers\Etc\HOSTS. Remove all entries except 127.0.0.1 localhost and see if you can get through now.

I am not sure exactly what you mean. Can you break it down for me. I am not very knowlegable on this subject.

Start -> run -> notepad -> Ok

File -> Open ->C:\Windows\System32\Drivers\Etc\HOSTS

Delete all lines except the one that lists 127.0.0.1.

I did exactly what you said. I dont know what to do next. It will not let me save since it is a read only file. Thanks for the help.

If you're an admin you should be able to adjust permissions on the file.

AVAST! has an option to do a Rootkit scan upon boot. Try that.

Or, as noted, boot from a "Rescue CD" that does a scan before Windows loads. F-Secure makes one of these available, too.

Getting those needed files would be easiest if you have another PC available. If not, you could even create and boot from a Linux Live CD (try Ubuntu), go onto the Internet from the Linux Boot CD, and get the needed scan files that way.

Is this what it should look like?

#

Yeah, you got it. If necessary, remove the Read-Only attribute on the file by going to its location, right-clicking it, and choosing Properties to reach the Read-Only checkbox.

Also, Avast is not the greatest antivirus product out there. If you are able to reach other security sites now, try that AntiVir bootable CD for a second opinion.

1) run the command netsh winsock reset by using Start > Run. Then reboot.

2) post a HijackThis 2.02 log. http://majorgeeks.com/download5554.html

Another option is to take the drive out and connect it to a completely patched computer and do a scan that way. make sure not to log in as an admin in case things try to auto install on the clean computer.

This may do the same thing that Mech suggested just in a GUI.

Try using HijackThis to remove these:

C:\WINDOWS\winsvc32.exe

C:\WINDOWS\winsvc32.exe (two instances of this)

O4 - HKLM\..\Run: [winsvc32] winsvc32.exe

Also, based on the logfile's info, you should run Secunia's PSI utility and fix everything it says to fix (out-of-date Adobe Reader, Java, Flash Player, and other easily-exploited stuff).

I just tried a fresh install of avg and avira. It will start to let me install and then it will not complete.
