While I cannot offer specific advice, I can give a few general tips ...
1) Turn off 'restore points' within Windows. Many viruses use this feature to replicate / hide.
2) Your AV program should give you the names of the suspected trojans. Google the name & removal. You should get tons of tips / help, but use discretion as to which advice to follow.
3) Sometimes it's best to just do a clean install. If your data is backed up, you may want to consider this. However, do not depend on a system image backup. It's very likely that the virus is there as well. My personal method is to move known clean files (pics, music & such) to removable media (thumb drive, dvd, whatever) Once you have all of your files that you want, proceed with a format / re-install. Once your OS is functioning again, install your AV software and update it. Then scan your 'known clean files' before moving them back to your computer, just to be sure.
Hope this helps!
