Just to point up that Malwarebytes' Anti-Malware still can not handle this little devil. I am using Malwarebytes' Anti-Malware for about one year, scanning regularly. For last month I was unable to access any of these sites: microsoft.com symantec.com malwarebytes.org (including forum) kaspersky.com etc... I was unable to update Malwarebytes' Anti-Malware too. After eliminating networking or modem problems, I came to conclusion it must be some kind of malware, and it's pretty hard to find solution if you don't have access to security sites. Half an hour ago, after using conficker removal tool, everything is back to normal, I can normally access all this sites, and update normally. Thank you.
