When using such tools to download "questionable" files, you get what you ask for.. You're opening your computer up to a myriad of infection possibilities.. Since you know the problem starts when the program is used, simply stop using the program.

It would also be a good idea to scan your computer thoroughly with a good antivirus and antispyware program, just to be sure the computer isn't infected with malware.

Hope this helps.
