Tonight, my computer was attacked by the System Defender/Security Tool malware (I'm using Windows XP).
Essentially, I'm now getting loads of false alerts for spyware (one time, I did click 'remove all' but stopped when I saw that they wanted me to buy their BS program). Attempting to run Symantec AntiVirus didn't work, as I continued to double-click on the icon with no effect.
After a google search, I downloaded Malwarebytes to get rid of the two programs. It seemed to be working OK, and it had recognized about 15 files in 10 minutes, and then...a blue screen of death. I don't remember exactly what it said, but essentially it said that Windows had to shut down.
When I rebooted my computer, I tried to run the Malwarebytes program again, except now the Security Tool pop-up was telling me that "mbam.exe is a worm which will send out credit card numbers over your network". I tried downloading other antivirus programs, but I get the same message - the spyware is blocking the antivirus from running.
Is my situation hopeless? Should I buy an external hard drive, salvage what files I can and wipe my computer clean?
As I'm sure you can tell, I'm not an expert with computers, but any help you guys could give would be appreciated.
(Edit: I should also mention - when I reboot my computer, my wallpaper is gone (replaced by generic blue background) and my desktop icons disappear once the two spyware programs load. Also, every program I try to open - from Excel files to Solitaire - is blocked with the same message as when I try to open an antivirus program.)
