Hello all: First off, I want to thank everyone for providing so much useful information. This forum has been a lifesaver! So, I noticed my computer obtained a virus 2 nights ago - Backdoor.Tidserv!inf I came here and started reading the following thread: "Hacktool.Rootkit and Backdoor.Tidserv!inf" (can't post links yet, under 5 posts). The first thing this user was told to do was go through the 8-step process. Well, prior to starting with that, I fully uninstalled Symantec Anitvirus Corporate, using scscleanwipe. After that, I rebooted, then noticed the following error message upon start-up: Header - itouch.eve - unable to locate component. The body mentioned something about not being able to find MFC7.DLL. Now, I could care less about this - I just wanted to bring it up to see if this is something I should be concerned about (also, eventually getting rid of that error message would be nice). I then installed Avira. I ran the unpdate then did a complete scan. Upon finishing the scan, my computer locked-up, unable to do anything. So, I rebooted again. When I opened Avira up again after reboot, it appeared to have captured known issues/viruses. Then, I installed Comodo and ran a scan. That is up and running no problem. After that, I installed CC Cleaner. Ran that a few times until it stopped catching stuff (Although seems if I wait a little while, run it again, it keeps catching more stuff!). Now, here's where I basically run into a wall. I had previously installed Malwarebytes' Anti-Malware. Nonetheless, I tried to run the exe file to see if it would automatically update or something. Well, nothing happened. Then, I just tried to run the program itself, through the Start Menu - again, nothing happened. I tried rebooted and running the program - nothing. Tried running the exe file again, and nothing. I then proceeded to uninstall Malwarebytes' Anti-Malware - assuming I could just reinstall it at that point. Well, it took forever to uninstall, I actually went to sleep and saw it had completed in the morning. I rebooted, tried running the exe, and nothing. So, this is where I am at. I have no idea what's going on, everything was going smoothly until then. Is this something a virus is doing? How can I get Malwarebytes' Anti-Malware re-installed and running? Thanks everyone! I'll be on this thread all day, so if there's a question posted, I will respond to it immediately to the best of my ability. Unfortunately, the PC that's infected is at home, and I am currently at work. So, I won't be able to try anything until later today. Thanks again!
