My question is the subject line.
Unfortunately, I have lost my reference on this matter. Some time ago I saw an article in Discover Magazine by a guy who is assigned the task of protecting the entire WWW. It was an interesting read, but the topic that most caught my attention was he said to never do anything personally critical, meaning specifically on line banking, while having multiple tabs open.
Why? If you have Avast, Comodo, etc running.
And if this is true, how do you stop an intrusion like this? I ask because I usually have 4 tabs open at all times, my wife however has 15 to 25 tabs open at once. She's a crochet maniac and switches crochet patterns like guys switch radio (tv) stations, lol.
A second question would be; how safe is it to watch youtube videos? I watch a few, mostly music related, but my wife watches all sorts of yt vids, and her son is off the shelf watching anything yt (youtube)
