I an running an Acer Aspire 5810T laptop with Windows 7 Home Premium installed, and, starting friday, I have been plagued with a randomly-occurring message stating "You are about to be logged off. Windows has encountered a critical error and will restart automatically in one minute. Please save your work". Following this, the computer proceeds to restart. I believe it is due to a virus that came with some software I downloaded, but I am keeping an open mind.
I had Norton partially installed, and after running several custom scans, at least 30 viruses have been quarantined (although, I do not know how many of those were there prior to this attack); however the problem still occurs. My system is running slower than normal, and my programmes are more prone to stop responding. I have tried a system restore; however, I have error 1x8007001f and the failure to delete a certain file, and the restore fails. When I try to delete said file manually, I am told that the computer cannot read the file from the source/disc.
During the shutdown, I have tried the "shutdown -a" method; however, that fails too.
A new problem also surfaced today: my desktop wallpaper and image thumbnails will no longer show. I have tried to edit my wallpaper using "Personalise," but it will neither show my image thumbnails or allow me to select a piture or even a folder.
My laptop is about a year and a half old, with Windows 7 successfully running on it for just over 10 months. Any help whatsoever would be GREATLY appreciated, as I am really at the end of my tether over this. Also, I think it's safe for me to say that I am useless at computers, so it would be helpful if any advice could be phrased in the simplest way possible.
Thank you 8D
