Beware browser add-ons that promise to boost your Steam-based games -- you might be in for a rude surprise. Security gurus have spotted a known scammer offering Chrome extensions that claim to change your Counter-Strike: Global Offensive theme or help you gamble, but do nothing more than steal from your Steam inventory. It's not the greatest loss if you're a victim (the malware isn't compromising the games or your Steam account), but it'll probably leave you crestfallen if you spent ages collecting rare virtual objects.
