It id possibly because of three problems,

1) Mostly your computer May be effected by Virus/spyware:

Get good antivirus software(I prefer bitdefender8, it is free to download) and scan your computer. For spyware try spybot/Adaware.

2)Because of badsectors on the drive you Install those applications:

Uninstall those applications and install them on any other drive.

3) File currupted: Reinstall the applications. Before installing clean registry using any reg clean utility like Tuneup utilities/system mechanic.
