Malware infections can sometimes block anti-malware utilities or even make the computer unbootable, Microsoft has now came up with a free "Standalone System Sweeper" utility enabling users to get rid of those nasty infections allowing them to perform offline scans to remove viruses, trojans and rootkits effectively.

Microsoft Standalone System Sweeper allows users to download latest definitions and make a bootable CD, DVD, or USB stick which when booted from loads the Windows Preinstall Environment (Windows PE) to run the scan and clean infections.

Multi engine anti-virus/malware scanners are popular as an online service allowing users to upload and scan suspicious files with most popular anti-virus engines, however, the online solution is not practical in situations where the users needs to scan a lot of files and folders. For such need we have freeware utility "MultiScan" - allowing users to scan any number of files or folders using configurable, multiple, 3rd party, command-line anti-virus/malware scanners of their choice, all from a single interface.

MalwareBytes and SUPERAntiSpyware are two popular and trusted free software's when it comes to cleaning of malware ridden computers, but these automated signature based scanners become useless when you are dealing with a little known malware not yet included in the anti-malware database or when the malware is smart enough to detect presence of these utilities and terminate them, in such cases advance computer users resort to manual removal of infected files by taking help from tools like ARSwp, System Repair Engineer, SpyDLLRemover and ATool to name a few - today I am going to share a pretty little known but excellent must-have utility dubbed 'FreeFixer' which provides everything you will be needing to detect and get rid of those hard-to-remove malware files manually.

FreeFixer is an simple to use utility which allows users to scan and delete potentially unwanted files belonging to adwares, spywares, trojans, viruses and worms; unlike other signature based automated malware-busters FreeFixer simply scans all the places from where these malware gets loaded white-listing trusted known genuine files allowing advanced computer users to detect and remove unwanted files from getting loaded next time you boot your computer.

Advanced system information tools are very useful for detecting unknown viruses and removing them, there are plenty of free and paid utilities providing all the system diagnostic information at one place but free advanced security management tool ATool would be one of the most comprehensive of all.

ATool requires no installation and shows Windows Autorun, running processes, loaded DLLs and drivers, open-ports, BHOs, System users, hosts information and comes with an file and register manager.

Malware creators always try to be one-step ahead of security softwares, using increasingly professional techniques to outpace security software and improve their chances of infecting your computer, if you are stuck in a situation where your anti-virus and anti-malware software is not recognizing or is unable to remove the malware infection usually you are left with only two choices, either to format the computer and reinstall Windows or removing the infection manually.

Today, I will be sharing two excellent free utilities Anti-Rougue Windows Sweep (ARSwp) and System Repair Engineer (SREng) to diagnose and remove such stubborn Virus, Spyware, Adware and Trojan infections with ease.
