Had terrible recent problems with pc grinding to a halt and all memory being sucked up. Traced the problem and found a lot of people have similar experience with the vsmon.exe part of zone alarm. Using task manager and shutting down vsmon frees up the cpu instantly, but of course it kicks back in when you go online. Trouble is, i cannot access or remove the file as access is denied. Similarly I cannot uninstall zonealarm because of vsmon.exe. Vicious circle. Any help advice greatly received.
