No antivirus or antispyware protection is perfect, not even the expensive ones but a good mixture will help you clean your system and hopefully keep it clean. It is advisable not to run two or more anti virus applications.

For starters, download, update and run a full scan using the following product:

SuperAntiSpyware is exceptional and will remove the majority of difficult Trojans and Worms, not just the easy ones.

If possible it is recommended that you load the application in normal mode but run it in Safe Mode. Safe Mode can be started by continually pressing F8 during the boot sequence. However, if you are badly infected you might need to run SuperAntiSpyware more than once to help clean your system. If the only infections now being shown are in System Restore, once you are completely satisfied that you can boot normally, you can either delete the infected restore points manually, or temporarily turn off System Restore.
