I got system check virus like others on 12/30/2011. I was browsing the internet and suddenly I got a bunch of pop-up windows saying somthing along the lines of "Failed to save all the components for the file \\System32\\########## ... This error may be caused by a PC hardware problem" then a program called system check opened up and ask me to scan my computer and I cannot closed it. then it give a list of error on my computer like # of harddisk error, # Ram error... I lost everything on my desktop, start up menu and menu bar. I disconnect my PC from network right way. I goggled and before I found this forum, followed a suggestion to unhide folders and files, then rename a .exe file under application folder. then restart the PC, but I would get the pop up windows ( more than 20 of them ), I can close them one by one, but they would show up again and system check up window would open up again. I click stop button to stop it "running", but I cannot close it, I repeated unhiding the file and folder and renaming .exe then restart the pc, no use, and after a while, my monitor went blank ( showing enter power saving mode), I think I lost monitor signal. I cannot bring it back by enter ctrl+alt+del. I have to shut down pc by push the power button. So I checked micorsoft site for help. It suggests to run Safety Scanner. so I download it to a USB memory stick. Today, I power up my pc, then did unhide, rename .exe file then I ran the Safety Scanner for full scan. But after a few minute, my monitor went blank again. I don't know what virus will do to my PC if i leave it running for long time, so I shut down the pc by push the button. I found this forum now. But it looks like I cannot run any scan software for a while. What can I do? Please help. I am totally new to this virus world.
