I am glad to hear you resolved the malware problem but a Repair Install may not work for everyone as it depends on the type and extent of the infection.
In some cases a Win32.Patched
threat detection can be indicative of a dangerous polymorphic file infector
functionality such as Virut
. This type of malware typically typically infects .exe, .scr files, compressed files (.zip, .cab, .rar), and script files (.php, .asp, .htm, .html, .xml) and opens a back door
that compromises your computer
. Using this backdoor, a remote attacker can access and instruct the infected computer to download and execute more malicious files. With this particular infection the safest solution and only sure way to remove it effectively is to reformat and reinstall the OS
File injectors will seek out critical system files and insert its code into them. In many cases the infected files (which could number in the thousands) cannot be disinfected
properly by your anti-virus. When disinfection is attempted, the files often become corrupted and the system may become unstable or irreparable
. The longer this type of infection remains on a computer, the more files it infects and corrupts so the degree of infection can vary. Additionaly, the system has likely been compromised by backdoor Trojans
and there is no way to be sure the computer can ever be trusted again.
Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat
and reinstall the OS.
Backdoors and What They Mean to You
Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include:
• Reimaging the system
• Restoring the entire system using a full system backup from before the backdoor infection
• Reformatting and reinstalling the system
This is what Jesper M. Johansson at Microsoft TechNet has to say: Help: I Got Hacked. Now What Do I Do?
The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).
