Original problem: it seemed like my computer had a virus of some sort (fake anti-virus websites ALWAYS opening and trying to download things when I was browsing the internet), but no hits with MBAM scans or AVG scans. Step 1: I read the blog and thought the Powelicks post sounded like my problem, so I downloaded MBAR BETA. Extraction went fine, but when I tried to run the tool, I immediately got a message asking me about a specific .dll file. The message (from MBAR) said it was probably a rootkit causing the particular .dll file (which I did not take a screenshot of or write down). The message box gave me a Yes or No option to remove that file immediately. The message went on to say that if I wasn't sure, I should press "No", but that if MBAR crashed or was unable to scan, to close and restart the tool, and select "Yes" the next time. I pressed "No", the scanner crashed, and I restarted it, got the same message, and selected "Yes". Step 2: I tried to run the MBAR scan and get the attached error message. What should I do next?
