Also, is this a virus? Is this a bug in the program?I'm trying to remove a currently installed program, but when I click Change/Remove nothing happens....?Some error in PC. It is always better to depend on system restore so that un- identified errors are undone with out affecting the basic operating system. I suggest that you try to carryout system restore to a day previous to the day when there was no virus or any problems. It may be a few weeks or months back. You have to decide the date.
