Recently, I saw a trojan able to sneak itself into my f drive "System Volume Information" read-only folder without my knowledge. However when i tried to access this folder to delete the trojan, it prompts me access denied on this folder.
Why this folder is so special?
This folder is actually a part of System Restore; the tool that allows you to set points in time to roll back your computer. The System Volume Information folder is where XP stores these points and associated information that makes them accessible.
Read more about it here to change the access permission of the folder:
No wonder Microsoft wants people to upgrade to Vista...WinXP is not safe by itself.
I managed to clean this trojan by using NOD32 antivirus. Yeah!
