I had an adware/malware on my computer "trojan.popuper" that advertise on my desktop that my computer was infected. I purchase spyware doctor which seem to have quarantine the "trojan.popuper".
Before purchasing spyware doctor, I tried searching for the location and somehow, I think I may have deleted something I should not have. The desktop stop displaying the ad but is now blank white. I can still see my desktop icons but not the background.
Also, when I tried booting the computer in safemode. I can boot in safe mode until the log in screen comes up and I type my password. The password does not work for logging into safemode.
The same happen to my girlfriends computer. Except her computer still works in safemode.
My computer runs on Windows 2000 Professional and my girlfriends' computer runs on Windows XP.
