Another worm is making the rounds on Twitter via the goo.gl URL shortening service, often directing users to fake anti-virus software. Affected users might notice mysterious tweets that they did not write showing up on their feeds, many of which include goo.gl links that end with "m28sx.html."
If you click on these links, you are taken to a Web site that suggests your computer has been infected by a virus. The site encourages you to download what it says is anti-virus protection but is actually malicious code. Del Harvey, head of Twitter's trust and safety efforts, tweeted yesterday that the company was "working to remove the malware links and reset passwords on compromised accounts."
