Here are three emails you don't want to see in your inbox today.
Although the emails may claim to have been sent by the likes of LinkedIn, YouTube and Google the truth is that the headers are forged, and the emails have been specially crafted to look like legitimate communications from online firms.
Clicking on the links could send your computer to Canadian pharmacy-like spam sites offering to sell you Viagra, or even webpages hosting malicious payloads.
Always be careful about clicking on links in unsolicited emails. Hover over links with your mouse to tell where it's really going to before clicking, and keep your anti-virus and anti-spam protection updated.
If you're careless you could be falling into the spammers' trap, and putting your finances and data in danger.
