I’ve been using Avira free antivirus. Yesterday I downloaded Acrobat Reader DC and McAfee downloaded automatically at the same time. Should I use Avira or McAfee or both?

What you downloaded was McAfee’s Security Scan Plus, which is not an actual antivirus product. It’s more of a marketing tool – it checks to see if you’re running McAfee (and that it’s working correctly if you do) and if not it will ask if you want to download and install McAfee. SSP does do some basic checking of your system – it checks your memory for some malware, and checks sites in your browsing history with SiteAdvisor (now WebAdvisor) and alerts you if any of them are rated as unsafe.

As for running two real-time antivirus programs at the same time, no. It’s going to cause problems not least because each of them is constantly going to be monitoring what the other is doing, and that’s going to cripple your machine’s performance.

Thanks Hayton. That’s good advice. I’ll uninstall McAfee right now.

    For anyone else lumbered with Security Scan Plus thanks to a download oversight, rest assured it doesn’t run all the time; it’s there if you want an ultra-quick simple system check. But for most people the best thing to do is just get rid of it, especially if you’ve already got an antivirus program installed.

Interestingly — as if by magic — I suddenly got attacked by a virus called karmavil.info [bright blue screen & computerized voice demanding money]. I wonder if this was attached to McAfee Security Scan Plus?

Hi,

Unfortunately it was likely bundled with the reader download like McAfee was. And or,was a vulnerable version. You need to download software from developer websites,to avoid the shady characters.

There are sites that can help you clean up your machine,like bleepingcomputer.com, malwaretips.com,ands others where the community has volunteer experts. Do a Google search too,but you should never have to pay for this kind of help. Those that charge,could be worse than the problem you now have.

@jbike : karmavil.info isn’t a virus, it’s a suspicious advertising site. The home page for today says “Every Wednesday we select one lucky visitor to get a special offer from our sponsors, as our “thank you” for being a loyal Facebook mobile user.”

So, probably something that came from a Facebook app. The owners of the domain are hidden, the site was registered through a Panama-based secrecy outfit. I’d recommend scanning with AdwCleaner and/or Malwarebytes to get rid of anything the site has dropped onto your system.
