80000064.@ Trojan detected Tags: Security Trojan Windows 7 Last response: March 4, 2013 3:09 PM in Windows 7 Share Dameon106 March 3, 2013 10:06:33 PM Hello, Avast found a Trojan on my brother's laptop and placed it inside it's chest. But he can't delete them. He's tried a system restore point and the computer restarted saying that it was unsuccessful as the Windows/Installer file was inaccessible (this was one of the files that was infected) Tried system image recovery - disk with files on isn't being recognised Tried re-installing windows and it says no valid windows installation detected Been trying to solve this for nearly a week. Any advice would be very much appreciated.

This allows it to scan before Windows has loaded thus system files are not in use (ie. it can heal/delete them if necessary) Dameon106 March 3, 2013 10:42:50 PM I'm afraid that's already been tried and the problem has not been fixed. Avast was unable to repair or delete the infected file. Thanks for the suggestion.

Dameon106 March 3, 2013 11:17:35 PM Tried R-Kill initially then conducted boot time scan with Avast. Haven't tried Malwarebytes yet though. That was gonna be the next step but I wanted to see if any other suggestions would appear first. So you suggest going ahead with R-Kill followed by Malwarebytes? the great randini a b $ Windows 7 March 3, 2013 11:22:28 PM rkill http://support.kaspersky.com/5350 <--tdskiller malwarebytes or superantispyware rougekiller http://www.bleepingcomputer.com/download/roguekiller/ http://www.bleepingcomputer.com/virus-removal/remove-td... http://www.symantec.com/security_response/writeup.jsp?d... the great randini a b $ Windows 7 March 3, 2013 11:24:14 PM http://www.hiren.info/pages/bootcd moulderhere March 4, 2013 3:09:55 PM Kaspersky has there rescue CD's you could download and use to try cleaning the system. https://support.kaspersky.com/4162 Can't find your answer ?
