Hi. IF I AM POSTING THIS IN A WRONG CATEGORY, PLEASE MOVE IT TO THE CORRECT CATEGORY. THANKS.
I have a HP Pavilion g6, got in 2012.
Two days back this fake window started showing on my laptop. It says - user control - at top and is titled - Command Line Interface for Microsoft - there is a small R in circle icon after Microsoft - asking 'Do you want this to make changes to your computer? the name of the company was 'Microsoft Windows'. I was skeptical so I pressed 'No', the window pops up again in a second. After a few times, I suspected something wrong, wanted to shutdown the laptop. The window keeps popping up within that two seconds ! I kept at it and clicked shutdown 2 -3 times. Finally it shut down. Next morning when I turned it on, the fake window appeared again and again.
I shut it down and took the computer to an electronics / computer (sales/support) store. The man looked at it and said - "it looks genuine, some controls were probably turned off , so i will say 'yes' ". Then he clicked 'yes' and the window disappeared. It all looked normal again.
I turned on the computer after coming home - the window popped again - as I was told at the store that it was genuine, I clicked 'yes' . thought everything was ok now. Then I opened a pdf file. It did not open - The icon changed too - now the name of the file was MICRO.pdf or pdf.Micro ! I disconnected the internet & transferred most important files to a hard drive. During this exercise, I noticed. pdf icons & some mp.4 also changing. surprisingly mp.3 s stayed as they were. I have lot of pdf and .mp4 stuff on my computer for my volunteer translation work & also personal use.
I transferred some folders - almost all .pdf stuff has changed to Micro.
During the transfer, after about 15 minutes, a notepad window came -up. 'which language is this?' - i thought I accidentally opened some notepad document - so closed it. After a minute, it popped again. Closed it. Popped up again - then I read it quickly - It said something like - "&8%4#6@ what is this language? Ha ha. now you know. You can not do anything.only if you go to this site - only if you pay money, you will know how to get rid of this. only we can do this "" etc., etc.,
Now I understood. I stopped the transfers & shut off the computer and writing to you.
As of now, I understand my hard drive also has some Micro files.
