Two days ago, a colleague at work asked me to check out an e-mail received that appeared to be a â‚¬50 iTunes Gift Certificate. He does not use iTunes, so he was sure the e-mail was dodgy and asked me to take a look.
To confirm it was dodgy, I opened up the attached zip file and inside there was an exe file which had a Microsoft Word icon. An zipped exe attachment with an icon of a Word document is no doubt an infection and even still, as not everyone has Word, there is no way Apple would be sending out vouchers in a Word document.
As AVG AV (also a paid version) did not show anything suspicious despite having the latest definition, I sent it to VirusTotal, which is an online checker that checks it against something like 41 Virus Checkers. From what I recall, Just 6 of the lot reported it was an infection (I know ClamAV, McAfee & Sophus were three.) None of the other virus checker’s I’m familiar with showed anything suspicious, which include AVG, Eset, Kaspersky, Microsoft, Symantec or Trend Micro.
So common sense also helps. If you receive an e-mail that seems too good to be true, it likely is.
