Yes, you need to use SETool2 Lite v1.11 to apply the patches. XS++ cannot apply patches at the moment.
NO, it is not normal at all. My advice is to update your antivirus and make a full virus scan on your computer. Then download the SETool2 Lite again, and make sure that it is not infected with some malware...also my anti-virus is reporting the qamaker exe as a virus - is this normal?
