Hello, mbar asked me when it started up if I wanted to delete an entry that might be a rootkit. I forgot to take note of what it was, but after mbar seemed to crash I clicked yes the next time. The mbar results said nothing found, and I ran the fixdamage. Windows Firewall is working, but Windows defender won't turn on, I don't know if I need that. Avast is warning me, as in the screenshot attached, about a rootkit. I think it's just mbar though? The computer is still acting strangely; Chrome crashes, sometimes the computer freezes, sometimes it blue screens and restarts. I don't know if these problems are malware related. I really appreciate all your help, thank you. mbar-log-2013-08-03 (17-33-31).txt system-log.txt
