If I had a trojan horse in my system restore files can it still do damage?

I deleted the infected file and changed all the passwords on the sites I used. Could the trojan still do damage when in system restore files?

 

AFAIK it can not do any harm from with in system restore. My concern would be that at one time it was on my system. How did it get there? What damage has already been done? Has it absolutely positively beyond a shadow of a doubt been removed?

 

Yea its gone. I updated all my scanners again and ran and nothing came up.

 

It can do damage if you do a restore. For that reason, I'd consider your restore archives worthless. Disable restore, which will destroy all your archives and it's content. Then re-enable restore and let it start building good restore points again.

 

Ok I deleted all the system restores and made a new one.

 

I wonder if all the trojans that appear magically in the System Restore folder are false positives in old versions of files.

 

Thats something to think about.
