I think maybe it was a how-to troubleshooting article - I'm troubleshooting several things as usual and I'm trying not to create more problems when I have to install or uninstall. Something recently said to turn off av and anti-malware as one of its steps. I noticed online scanners like Trend Housecall state they work w/ installed av and anti-malware now - you used to have to turn off installed av to do an online scan.
Now av's include anti-rootkit scanning and I wasn't sure if things had changed back again. Then programs stopped including it in instructions and I stopped doing it w/out noting problems. Most programs included that instruction in their install instructions and some reminded you when you started the install. Back in the old, old days it was routine to turn off av protection before doing installs.
