Anti-virus, Anti-spyware software can really screw up
Well, I just spent 3 hours with Mcafee online tech support. My privacy software was rating me as a child each time I signed on, and my filter setting kept getting reset to the most restrictive no matter what I did. Rather that uninstall and reinstall right from the start, I contacted tech support and followed their directions. After two hours I ended up with completely nonfunctional anti-virus, anti-spyware, and privacy software that would not uninstall or re-install. Another half hour with tech support to use backdoors to the rigistry files to erase the mess, and another half hour to re-install the software. seems to be working now. If I didn't have 6 months left on the subscription I would have just switched to Norton.
They had no explanation why it worked for 6 months, then went wacky. Bet it was one of their automatic updates.
