When using Windows it is smart to run a good virus scanner. From my work, we get free use of McAfee on our home PCs. I had installed McAfee on my Windows environment on my Mac. McAfee warned me about not being able to update. Tried to fix it with their 'virtual assistant' but that did not help Tried to set up a chat session for support. IE crashed because of plugin trouble. Called the help desk. Had to wait for 20 minutes. Then had a call center agent on the line trying to help me (these people don't understand computers, they just run a script). The call center agent told me I had to install 'the latest versions of Java and Flash' on my Windows environment. I told her that I had neither installed on my system but she persisted. These were necessary components for McAfee. Sorry, Flash and Java necessary components for a security solution? That is funny, really. She did not believe me that I had been running McAfee for two years without Flash and Java and just sent me an email telling me to install them (or get stuffed). She shut down her phone but left the line open. After 15 minutes or so I hung up. I spoke to a supervisor later and she talked to the high tech guys who confirmed that McAfee requires flash/java to be installed. Are you kidding me? The most often exploited inroads into a computer system are required components for a security system to protect it? I have now removed McAfee entirely (and installed another virus scanner), but really, not having this kind of a nightmare every day (only once in a while when I fire up the old Windows) really makes me happy I'm not a regular Windows user.
