Gmail users might need to up their email security practices.

Some Gmail users have become victims of an elaborate “phishing” scam. The scam tricks users into providing their login details.

Fake emails are received — sometimes from the user’s own address book — that contain attachments that look like PDF files.

However, when the user clicks on the attachment, he or she is redirected to a “phishing page” that looks like the official Google sign-in page.

If the user then provides login information, the attacker is able to go through the user’s email account at will.

U.K. news sources claim the phishing pages do not appear to trigger the Google security warnings that are used to keep Gmail users safe.

Those same news sources said even security experts have difficulties distinguishing the phishing page from the actual Gmail login page.

Experts recommend that computer users use malware protection on their systems, such as Malwarebytes, along with an antivirus program such as AVG, Avira, Avast or Webroot.

Even free versions of this software provide excellent protection.

As a further precaution, make sure to clear out temporary internet files on a regular basis. One recommended program for doing this is CCleaner.

If a user is logged in to Gmail and is redirected to a page that asks them to log back in, there is a high probability that the page is suspect. Do not give any passwords out to such pages.

Remember, a computer is just like a car — it requires regular maintenance to remain at peak operating performance.

Users who don’t use antivirus and malware protection programs at least once a month run the risk of their computers becoming infected with viruses or malware.
