That's the decision I would have made if this were my system. Backdoor Trojans, IRCBots
are very dangerous
because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to to gain unauthorized access to a computer and take control of it without your knowledge. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS.
Some types of malware can result in a system so badly damaged that a Repair Install will NOT help!
. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Starting over, reformatting the drive and performing a clean install of the OS removes everything and is the safest action.
