A sysrestore might not be enough, the trojan/virus could already be in those too (or in memory).
I think you should consider another AV program like f.e.
Free Avast! 4 Home Edition.
Stinger is a stand-alone utility used to detect and remove specific viruses. It is not a substitute for full anti-virus protection, but rather a tool to assist administrators and users when dealing with an infected system. Stinger utilizes next generation scan engine technology, including process scanning, digitally signed DAT files, and scan performance optimizations.
