My laptop won't do anything after install adobe flash player. When it enter startup, it automatically go to system repair and it seems windows can't detect any problem. Any suggestion how can i solve this? I think it is a virus from adobe flash i downloaded earlier.
At boot mad click function key F8 then choose "last known configuration" see if that gets you back to normal then renew your AV with an update and scan as well as use malwarebytes then try installing flash again...
Try booting from your W7 installation dvd and running startup repair. It may also be worth running SFC Scannow. Open command prompt as administrator, type sfc /scannow. Hit enter.
