FLORIDA -- My recent experience (October 2013) with tech support at Malwarebytes was amazing for the level of involvement and attention to my situation. I'd been using the free scan-on-demand service for a long time & decided to upgrade to paid. Before I got to it, I had a browser hijack by AVG toolbar/search via a freeware download (checked No on options but they forced it anyway). After eliminating it I was still concerned about using a credit card for the chance there may be a hidden keylogger, etc.
I told MBAM of my concern. They said it would have been detected in the full (free) scan, but they could do some further tests. At this point I was still a non-paid customer-- but they were extremely thorough with 7 tests in all (one was ComboFix). And it turned out the hijacker AVG had not been entirely deleted as I'd thought-- MBAM's tests took care of that.
I was pleasantly surprised at the attention to my situation as a non-paid user, and also since many companies are difficult or impossible to directly contact for support (such as Google)-- or they do a minimum of support, or else don't satisfactorily address a problem. The product itself is great,-- I believe superior to almost anything out there for what it does on both the free and paid versions. The paid version blocks 'possibly malicious websites' such as those with suspicious or malicious freeware downloads.
Malwarebytes is a company that is offering a free download of their anti-virus malware. Be very careful in downloading this software. It has been doing strange things to computers. Don't believe the reviews you read. My story is I downloaded the software. It did its thing and I then uninstalled the software. I then find that windows Vista and drivers had been removed. I have seen other stories about Malwarebytes and their problems. Please be very careful.
CANADA -- Since downloading Malwarebytes my comp. is in a mess. They downloaded another product also with pro in the name and the tech that did this put files in places they shouldn't be. I will now have to go and have a professional clean out my comp. as they also denied me access to these files, put Firefox on there also can't delete any of that. I'm in a mess, DO NOT DOWNLOAD THIS SOFTWARE. I paid as I got the upgraded version, did get my money back, only good thing about this whole mess.
