I'm sorry I haven't responded earlier. I did several full scans of MSE and I can say that the PC seems clean. On one of those scans I decided to delete the folder in which the hack tool was discovered. I also deleted other folders of which these tools were found. I am currently using ESET smart security Premium which expires now in 4 days. I guess you can mark this thread as solved. I am now going to use both ESET and MSE.
