The computer is a Dell desktop, with 4 profiles: Mine, one each for my parents, and one for my sister. My sis's is restricted, while the others are administrators. I was using mine at the time.
The other day I was browsing on the internets normally. I can't recall going anywhere fishy. Perhaps the closest is when I tried to download a YouTube video from a site I'd never been to before...
Unexpectedly, a box popped out to ask me to install Antivirus XP 2008. I assumed it was a pop up, but didn't see any X or whatever. I looked down at the tray, and the box for the installation had the logo next to it from running a .exe file. I right clicked that and did Close. It didn't respond, and the Not Responding box came up. I clicked End Now. A little while later it popped up again. This time I just opened the task manager and ended the process.
I assumed everything was fine.
When I was done on the computer, I closed FireFox and was horrified to see the background changed to a horrid blue, with "Warning! Spyware detected on your PC!" in a yellow and blue box in the middle. I right clicked for the properties, but Desktop and one other, I think it was appearances, were missing. I looked on the internet about that problem, and some people recommended SuperAntiSpyware. I downloaded it and ran it, then went to watch tv with a sinking feeling. I believe at the time already the internet was running slowly, and certain websites were 404s.
I went back to the computer before bed, but it all seem to have messed up, like it was tying to log me off. There also seemed to be a blue screen of death. I turned off the computer, feeling really bad. The next morning, I tried to turn on the computer to run the SAS again. I decided to see if the background problem was only on my profile(stupidly) and opened my dad's. I breathed a sigh of relief when it was his normal background, but then did facepalm when it turned to the blue one.
I believe I tried to run the SAS, but nothing would respond. I turned off the computer, then turned it out again. When it got to the part where it says, "Windows is starting up..." before the profile selection, it was stuck. I began feeling more distraught. I turned on the comp in Safe Mode and ran SAS. it found stuff, but didn't solve the problem.
I looked on Google on my laptop about Antivirus XP 2008, and deleted a fishy sounding C:/Program Files/(random letters and numbers).
Then I searched the C:/Windows for the .bmp file for the Spyware Detected image. I deleted that, and searched for everything that had the last 4 characters of it and deleted those. I also found the same thingy in msconfig, and unchecked it. I looked in regedit and deleted the registry(I hope). I changed the registry values of the Desktop thing, and restarted my comp in normal mode.
I used my profile this time, and was able to load and not freeze up. I was pleased to see that I was able to change the wallpaper, and had the tabs back in the properties menu.
However, I opened FireFox and searched Google for Antivirus XP 2008 again, to see if I forgot anything, but I saw that all the results would redirect me. Some sites are still 404s, and it's running slow as molasses. I found a direct download of Malwarebytes, which I heard could finish it off, but when I tried to run the .exe, it said the setup was corrupted.
What can I still do to fix this? I was going to do a system restore, but apparently the computer never made one. I am willing to reformat, but only as a last resort, and if I'm able to back up all the emails of my mom's, and documents and stuff.
Your help is appreciated. It's really making me sad all the time now, and having a feeling of hopelessness, especially since I'm one of the most computer savvy people I know in real life. Perhaps it also seems bad to me, because I'm really clean and safe and stuff on that desktop, while on my laptop I can be risky, yet it still works fine. (Except for not allowing login pages like eBay, Hotmail, Yahoo, etc. to work, but I suppose that's another thread.)
