Avast says I have this in the file
C:\System Volume Information_restore{58E30938-66A1-4D08-9DCD-360CE25B3A88}\RP170\A0017254.dll Repair is not available. Is this safe to delete?
If it is possible you can delete this, remember it’s diificult or impossible to remove the trojan by the anti-virus the best thing to disable system repair. Remember the system volume information is nothing more then an system restore folder if you choose to restore your windows all the information for putting back an rstore this folder will be used.
