Unfortunately, McAfee is one of the worst offenders in my experience [1]. I seriously doubt you can disable it completely from user space, given its habits of interposing on device drivers and burrowing into other kernel bits [2]. [1] IMO it's a cure that's worse than the disease, but that's a rant for a different thread. [2] McAfee actually sued MS for "anticompetitive" behavior a while back, after the latter closed a bunch of security loopholes in the kernel that virus-writers love but McAfee also depended on (including the interrupt dispatch table IIRC). >> My advice: check out the cygwin FAQ about BLODA, uninstall anything listed >> there (or install a fresh VM image somewhere without those) and try again. >> If it's still a problem, somebody more familiar with X than me will have to >> take over... >> > If I can get the authorization for a VM test without A/V, I will and > the results will be posted here either way.
