I'm seeing some odd errors/warnings in my event logs and am wondering if they can be related to someone trying to hack my computer. I'm seeing a lot of MRxSmb 3019 warnings, and periodic System Error 1003's. I'm running a number of protection programs (Windows firewall, Norton Protect, and Previx1) and none have come up with anything unusual, although I did discover recently backdoor.sdbot on the PC (not detected during any scans) and have removed the three programs (winupsrv.exe,winsrvup.exe, and one other) that were associated with it and scanned my registry and removed anything that referenced these programs. I've also seen Remote Desktop to this computer freeze up quite often (the most recent showing the MRxSmb 3019 errors). So, does anyone think these things can add up to a hacker attack of some sort?
