Hi, I came home today to find an .exe file on my desktop..i scanned the file for viruses and found it to be free of them. I tried to delete it but it says it is being used by another process. I also tried this in safe mode..but to no avail..When i click on it..it says it is not a valid Win32 application..Please help me as it has an obscene filename..which I do not want my kids to see..thanks
