Failed to login into windows XP due to deleted registry keys

[Benjhonson]

I was using Microsoft windows XP operating system my desktop from last one year. Few days ago while browsing across the internet I have downloaded and installed McAfee antivirus software for achieving the security. After installing McAfee antivirus software I updated it by downloading the latest patch. I started to scan the system so that if any virus, malware etc are found then it could be fixed easily. After scanning the system it found some of the virus and therefore deleted it. It also deleted some of the registry files due to which I can’t login into the system. I need solution so that I can fix this problem and login into the system safely.
