Hi, I had a look at your logs over in your recent malware topic and its pretty clear from them that you have installed at some time P2P File sharing programs........There are legitimate uses for P2P File sharing, but a lot that I come across are used for the downloading of files,(especially music, videos, games etc) that breach both National and International rules on copyright. There is currently a major crackdown on folks who use File Sharing to break copyright rules and heavy penalties are being imposed......often it's the young folks who are tempted to do this, their parents often being unaware, but it might be as well to check that your machine is squeaky clean in this respect, just to be on the safe side.
File sharing is a well known vector for the distribution of malicious code and large numbers of machines are infected by this route, the effects can be devastating and sometimes a format and reinstall of the operating system is necessary...... In addition it is said that otherwise malware free files are "seeded" with extra code in an attempt to create problematic system performance and persuade folks that files with an unproven provenance can make for big trouble......For these reasons I recommend that you uninstall all P2P file sharing or similar applications, utorrent. etc. In addition any files that you have downloaded via utorrent etc where the provenance is not 100% are best deleted and the recycle bin emptied.
Making a disc image is a wise move and highly recommended when your machine is running well again and in its "perfect state" Win 7 has its own built in imaging facility or otherwise Acronis, Ghost, Paragon are good( paid for versions) or free versions are available from here:

Its always best to take your first full disc image when you know that your machine is running fast and sweet, with all appropriate Windows updates installed, with no virus or malicious elements present, with junk files deleted, all unneccessary or unwanted applications removed, fully defragged and with updated anti virus, firewall and anti spyware protections in place. Remember , if you make a disc image of an "infected or badly running system and then use it to reimage your hard drive you are just making things tough for yourself as the problems will just be propogated....
However, subject to the above paragraph if, at the moment, you do not have a disc image kept safe on removable media, then I recommend you make one immediately.......In the event that you hit serious trouble that cannot be resolved in a timely or cost effective way by the usual means, then you will be able to reimage and have your machine up and running in less time than it takes to walk the dog!
Regards
