Solved How to remove a Trojan virus

Dell / Inspiron 17r
October 22, 2019 at 17:38:39
Specs: windows 10, 2.3/8
When I turned on my PC, I got the following message from iolo System Mechanic (19.0.0.1) "...prevented a malicious program from harming your PC." The virus was W32/Trojan-EXVP-6414 and the affected file is "C:\Program Files\common files\McAFee\PEF\core\uninstallpef.exe." I ran the iolo System Mechanic full scan and that said: "Failed to fix.". I then ran Housecall, McAfee, and Malwarebyte and all three said there was no problem.

I don't know a lot about viruses and virus removals; is it safe to continue using the PC with this virus still affecting a file? Should I delete the entire McAfee application or is there another procedure I can use?

Thank you.
Brian W

Hi again Brian, I would uninstall McAfee using their uninstaller. The MS AV ( which is what I use ) will then kick in.

In the years on this board I've seen many a computer screwed up after using programs like System Mechanic. Everyone to their own but I regard that sort of stuff as snake oil and quite unneccessary..

Always pop back and let us know the outcome - thanks

Johnw,

Thank you for your assistance. I deleted McAfee and now am using the built-in Microsoft AV. I also use the free version of Malwarebyte. I don't know all of the anti-virus protections offered by McAfee. Is the MS AV and free version of Malwarebyte sufficient or should I upgrade to the premium (paid) version of Malwarebyte?

Thanks again,
Brian W

Derek,

Thank for your comments about System Mechanic. Is it possible that this program produced a false positive in that three other programs said there was no virus?

Thanks again,
Brian W

"Is the MS AV and free version of Malwarebyte sufficient"
If only trusted users, that is enough Brian. If all & sundry use the comp, get the paid version of Malwarebytes.

"Is it possible that this program produced a false positive in that three other programs said there was no virus?"
That's exactly what happened.

One more point. Make sure that "scan for root kits" is checked in Malwarebytes settings. It is never set by default but I feel that it is a very important option and should be turned on.

If you feel the need for more or pay for protection, I have used Webroot for many years now with good results. Otherwise JohnW's suggestion should be good for you.

You have to be a little bit crazy to keep you from going insane.

Johnw,

Thank you for your response; I’ll stick with the free version of Malwarebyte as I am the only one who uses the computer.

Thanks again,
