It sounds like malware, certainly. Malwarebytes might pick it up and deal with it, but I would suggest that first you read this (quite short) thread from last year, especially the final wrap-up from Ex-Brit : https://community.mcafee.com/thread/7078
What he says chimes with what I was going to suggest. The link he mentions I couldn't see in his signature, but in case I've overlooked it that link is http://www.virustotal.com/about.html
And it's only fair to say that I had been considering recommending prevx as a detection tool. Now, I'm not sure. It certainly lists qxx.exe as an undesirable program, but its description of it as a startup program isn't supported by the bleepingcomputer startup list at http://www.bleepingcomputer.com/startups/
If Malwarebytes (in safe mode, if necessary) doesn't fix it, see the advice about HijackThis in https://community.mcafee.com/message/139084
or - as the McAfee alternative - ask in the Getsusp group for assistance - https://community.mcafee.com/groups/getsusp30-beta-feedback
That tool I understand is still a Beta Test product and not yet widely available, so you have to ask for it.
Hope this helps.
Thank you, thank you, thank you! The link to Ex-Brit's previous comments was great. I went ahead and downloaded the free version of SUPERAntiSpyware and it worked like a charm. Detected and removed the troublesome malware. I was very pleased with this product and will be purchasing the full version. Didn't have a chance to try out Malwarebytes, but I'm sure it would be a good choice as well.
Before I read your reply and the post(s) by Ex-Brit, I was also tempted to purchase and download Prevx. Glad I didn't. Although it may be legit antivirus software, it seems as if there's enough confusion that it may allow a virus program with the same name to infiltrate your system. This is unfortunate for the real Prevx.
Thanks again to Hayton and Ex-Brit (and SUPERAntiSpyware).
