Hi, I am helping with a friends computer. He had managed to get himself infected with various malware, trojan and viruses. One of which according to the log files had switched off his antivirus and windows firewall. I have installed mbm and removed the majority of them, which enabled me to switch the antivirus (AVG) prorgam back on. I have now installed comodo and run CC, Spybot, Super Anti-spyware, Hijackthis and Combofix. mbam still says rootkit.agent is present at str.sys I have tried to delete this using reboot, and fileassasin, but no joy. Combofix said it fixed it, but a different version of rootkit has appeared and now AVG is saying mbam files are a virus - packed.rolex. I have included the log files from the scans. I hope someone can help me.
