The first thing to do is check if there is any other malware on your system. AdAware isn't really an anti-virus or anti-malware scanner, so I would try both Malwarebytes' Anti-malware and SUPERAntiSpyware.
Follow the instructions below;
1] On this computer, download and install both Malwarebytes' Anti-malware and SUPERAntiSpyware. One at a time starting with MBAM, run each, update their definitions, then run a full scan.
2] If this virus doesn't allow you to use both MBAM and SAS in Normal Mode, try them both in Safe Mode. If you are unable to update either, run just MBAM in safe mode because it's installer file should have installed sufficient definitions to perform an initial scan and remove this.
3] If this virus doesn't allow you to download MBAM and SAS, use another computer, (relatives, friends, etc), to download both the MBAM and SAS installer files, then copy them to some external media like a CD or memory stick. At the same time, download MBAM's definitions from http://data.mbamupdates.com/tools/mbam-rules.exe and copy them to the media. Then use that to copy to your computer.
4] In some instances malware will try and prevent known anti-malware scanners from installing. In those cases, before copying MBAM to media, rename the installer file to some other name, eg "GoGetum.exe". Copy the file to the infected machine and run it to install MBAM. You may have to rename the MBAM executable application file to some other name before running it. Then use the updater file to update MBAM then run the scanner.
5] You 'may' have to run the MBAM scanner from Safe Mode.
6] After scanning with MBAM, then run SAS.
See if that helps, and please, go get a recognised anti-virus scanner installed, and make sure you have a firewall which is turned on.
