Computer is a Dell Inspiron 1545 running Windows 7 64-bit. Turn laptop on goes directly to blinking cursor. No Safe mode or other options available. Pulled drive to scan on SATA connection using Vista Home Basic 32-bit with Norton IS 2010 and immediately detects boot.tidserv. Full scan will detect and claim to remove. Ran TDSSKiller (Kaspersky) tool, and finds infection on local drive now. It only finds 1 (Vista drive), and click Reboot now... Have done this 3 times to no avail. I just downloaded the most recent version from Kaspersky for TDSSKiller before starting this. Haven't used any fixmbr type programs on Win7 drives yet. Any recommendations? Not sure what antivirus is installed on laptop (New customer).
