Google garnered headlines all week with its new Chrome browser. Rival Microsoft announced it will release just four patches next Tuesday, but that may not be cause to think the day will be an easy one for those responsible for keeping systems patched. Also looking ahead, Apple is expected to announce iPod news. Otherwise, a warning was issued about new trickery from spammers and in case we all weren't aware of it by now, social-networking sites could be ripe for malware.

1. Continuing coverage: Google's Chrome browser: Google offered up a Labor Day holiday surprise when it inadvertently posted a look at its new Chrome browser at an unofficial company blog. Google then made the news official later in the day and released the browser, which shifts the landscape of that market, in beta on Tuesday. Reviewers found the Chrome browser fast, functional and, following the Google home-page pattern, with a stripped-down look. By week's end, though, the first security problems had surfaced.

2. Upcoming Microsoft patch lineup could be 'massive,' says researcher: A word of warning for next week -- don't assume that because Microsoft is releasing only four patches this month that it will be a snap to deal with them. "It's not going to be an easy month, what with all these different applications and different operating systems affected. Patching will be a lot more involved than you'd think with just four bulletins," said Andrew Storms, director of security operations at nCircle Network Security. The job of applying the patches could be "potentially massive," he said.

3. Researchers build malicious Facebook application: A research team built a malicious Facebook program to show the perils of social-networking applications. Their experiment shows how easy it could be for a miscreant to trick a big group of users into downloading an application that seems harmless, but that contains malicious code.

4. What's at stake for Apple at Tuesday's iPod event?: Apple has invited a select group of reporters to an event Tuesday that seems to involve the iPod -- the sort of event that used to set Apple fans aflutter. But a new sentiment has emerged this time around, approaching what has become an annual September IT event, with Apple announcing iPod news. Some users are expressing wariness about any forthcoming Apple products as they recall that recent product launches haven't lived up to the marketing hype from Apple.

5. Sony recalls 73,000 Vaio laptops due to burn hazard: Sony recalled 73,000 Vaio TZ laptops because a manufacturing defect could cause them to overheat in some circumstances. Wiring near the hinge of the computer models could short circuit, Sony said. One person has suffered a minor burn and Sony has gotten 15 additional reports about computers overheating.
