Web-based warnings often tell us that our PCs are at risk from viruses and other online threats - but how can we be sure these warnings are genuine? Many are asking the question, "What is the McAfee virus warning on my computer--is it real?" Here, we'll answer that question.

Genuine vs. Fake Anti-virus Notifications
It isn’t unusual to spend a few hours browsing the web to come across a pop-up message informing you that there is a virus on your PC. This is a tactic used by legitimate and malicious providers of antivirus (AV) software – so how can you be sure if the message is genuine?
Plenty of users have fallen victims to “fake" antivirus software installed via pop-ups of this kind; basically it is seen as a scare tactic to tempt you into downloading “free" software that turns out to be a fake AV tool designed to slow down your PC, lace it with adware and spyware, and generally fool you into submission.
The “success" of fake antivirus software that has been downloaded and installed by unsuspecting users (who then find the AV software either doesn’t work or is a sophisticated spyware and adware tool) has led to at least one reputable name copying the tactic: McAfee.
You can see why they would think this is a good idea – it is better that a reputable name appears as a pop-up than a non-reputable piece of malware. This has enabled McAfee to attract new customers via the carrot dangling and offering their free antivirus scanning tool – a utility that finds infections but doesn’t delete them.
However, this tactic opens floodgates. If McAfee is prepared to run pop-up ads to display antivirus warnings in a browser window, then why shouldn’t the scammers continue to push this tactic?

Controlling the Truth
The fact is, it doesn’t matter whether or not the McAfee virus warning on your computer is real or not – if you are concerned, then you should do something about it. However, doing something about it doesn’t mean that you should click the link and download whatever scanning tool is being offered.
Instead, take some time out, reboot your PC, go back onto the web and search for a suitable antivirus solution that will scan your PC for you and report back on its findings before proceeding to clean the infections.
Clicking on antivirus alert messages on web pages will not fix your PC; it's more likely they will damage your computer.
