this has been occurring ever since my computer was diagnosed with a trojan. i removed it, and ever since then no .EXE files will open. I will click on any .EXE file, the revolving circle signifying loading will show for a second, and then it won't load at all - the program is not present in the task manager either. the weird thing is, there is no difference in safe mode. no .EXE file will run in any variation of safe mode. this prevents me from running ANYTHING apart from the command prompt, viewing folders, and notepad. i cannot load the internet, a virus scanner, NOTHING. it is difficult to fix something when one is literally unable to access anything. i have attempted the 'repair my computer' option when i press f8, but it says it can't be repaired automatically. i downloaded a registry fix from a different computer, but it reads the message "Could not import exefix.reg: Not all data was successfully written to the registry. Some keys are open by the system or other processes". to summarize: I cannot load a registry fix, virus scanner, or the internet. i STILL cannot open .EXE files in any variation of safe mode. i do not have the windows 7 disc so i cannot reformat. additionally, the trojan appears to have erased all my system restore points, so i cannot restore to any previous time.
