First, I say again, Thank you for all the time you are spending helping me.

No problem :).

I did, however delete the Trojans that were detected.

Good to hear! The rest of what that scan found were vulnerabilities from outdated software, which isn't actually any malware, but still good to know about. :thumbsup:


Are you still encountering the odd startnow symptoms? Please let me know. :)

no sir. I used the computer for about a half hour, starting and restarting each browser. I found no unexpected actions. I did a full scan with Malwarebytes and MSSE which all showed clean.

Excellent! I am glad to hear that! :thumbup2:


Since you said that the updates went fine, I will give you some suggestions for security software, but first, ComboFix must be uninstalled :):

The following will implement some cleanup procedures as well as reset System Restore points:

Click Start > Run and copy/paste the following bolded text into the Run box and click OK:

ComboFix /Uninstall

Please consider using these ideas to help secure your computer. While there is no way to guarantee safety when you use a computer, these steps will make it much less likely that you will need to endure another infection. While we really like to help people, we would rather help you protect yourself so that you won't need that help in the future. :)

Please either enable Automatic Updates under Start -> Control Panel -> Automatic Updates or get into the habit of checking Windows Update regularly. They usually have security updates every month. You can set Windows to notify you of Updates so that you can choose, but only do this if you believe you are able to understand which ones are needed. This is a crucial security measure.


It is really dangerous to go online without an antivirus. Without one, you are extremely likely to get infected and the consequences could be even worse next time. The following are excellent free antiviruses. Be sure to only install one.

avast!.
AntiVir
AVG

Please consider installing and running some of the following programs; they are either free or have free versions of commercial programs:

Spybot-Search & Destroy
A tutorial on using Spybot to remove spyware from your computer may be found here. Please also remember to enable Spybot's "Immunize" and "TeaTimer" features if you don't have the resident part of another anti-spyware program running.

SpywareBlaster
A tutorial on using SpywareBlaster to prevent malware from ever installing on your computer may be found here.

SpywareGuard
A tutorial on using SpywareGuard for real-time protection against spyware and hijackers may be found here.

Please, consider maintaining a firewall with HIPS (Host Intrusion Prevention Systems). Firewalls are extremely important and are the first part of your computer's defense. HIPS stops malware by monitoring its behavior and it's very important, too.
A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet.
If you are using the Windows Firewall please note that it doesn't monitor or block outbound traffic and is therefore less effective than other free alternatives.

These firewalls are good and do have free versions available A tutorial on understanding and using firewalls may be found here.


If you use Internet Explorer, it is a good idea to use IE-Spyad for ZonedOut which provides protections against malicious websites. (Requires 2 downloads)

Please keep these programs up-to-date and run them whenever you suspect a problem to prevent malware problems. A number of programs have resident protection and it is a good idea to run the resident protection of one of each type of program to maintain protection. However, it is important to run only one resident program of each type since they can conflict and become less effective. That means only one antivirus, firewall and scanning anti-spyware program at a time. Passive protectors, like SpywareBlaster and IE-Spyad can be run with any of them.

Note that there are a lot of rogue programs out there that want to scare you into giving them your money and some malware actually claims to be security programs. If you get a popup for a security program that you did not install yourself, do NOT click on it and ask for help immediately. It is very important to run an antivirus and firewall, but you can't always rely on reviews and ads for information. Ask in a security forum that you trust if you are not sure. If you are unsure and looking for anti-spyware programs, you can find out if it is a rogue here:

http://www.spywarewarrior.com/rogue_anti-spyware.htm

A similar category of programs is now called "scareware." Scareware programs are active infections that will pop-up on your computer and tell you that you are infected. If you look closely, it will usually have a name that looks like it might be legitimate, but it is NOT one of the programs you installed. It tells you to click and install it right away. If you click on any part of it, including the 'X' to close it, you may actually help it infect your computer further. Keeping protection updated and running resident protection can help prevent these infections. If it happens anyway, get offline as quickly as you can. Pull the internet connection cable or shut down the computer if you have to. Contact someone to help by using another computer if possible. These programs are also sometimes called 'rogues', but they are different than the older version of rogues mentioned above.

Please consider using an alternate browser. Mozilla's Firefox browser is a very good alternative. In addition to being generally more secure than Internet Explorer, it has a very good built-in popup blocker and add-ons, like NoScripts, can make it even more secure. Opera is another good option.
If you are interested, Firefox may be downloaded from here
Opera is available here: http://www.opera.com/download/

For much more useful information, please also read Tony Klein's excellent article: How did I get infected in the first place

Hopefully these steps will help to keep you error free. If you run into more difficulty, we will certainly do what we can to help. :)

done

Please either enable Automatic Updates under Start -> Control Panel -> Automatic Updates or get into the habit of checking Windows Update regularly.

This is SOP for this computer, the 5 others in my home network and every one I refurbish or work on for friends/family/clients.

It is really dangerous to go online without an antivirus. Without one, you are extremely likely to get infected and the consequences could be even worse next time. The following are excellent free antiviruses. Be sure to only install one.

as stated in my original post, I use Microsoft Security Essentials both here in my network and for others. Since it is obviously not "all I need," I have looked into what else I should do. I purchased the Malwarebytes product after some study. Staff at the Malwarebytes forum state that it will run along with MSSE with no problems, especially since I am running Windows 7, 64 bit. I have configured MSSE exceptions for Malwarebytes files and processes as instructed by their forum staff. For years I have heard and adhered to "only one antivirus," but it seems now, under certain conditions, this may not be true. Unless you specifically respond to me that I should NOT have them together, I will run them both. Obviously what I have been doing was not enough.

SpywareGuard. A tutorial on using SpywareGuard for real-time protection against spyware and hijackers may be found here.

I would appreciate some further claification here. Running MSSE and Malwarebytes, both with "real-time protection," do I really need another anti-spyware? I will follow your suggestion.

Please, consider maintaining a firewall with HIPS (Host Intrusion Prevention Systems). Firewalls are extremely important and are the first part of your computer's defense. HIPS stops malware by monitoring its behavior and it's very important, too.

I am behind a Linksys router and I have been running the Windows 7 Firewall. I have quite a bit sweat equity invested in setting rules for some of the programs I use, Synergy and Crossloop come to mind. I just downloaded, installed and configured Outpost 64 bit suite, using only the firewall, then uninstalled it. I am not comfortable using it, again, unless you SPECIFICALLY tell me I need a firewall different from the one provided with Windows 7.

Please consider using an alternate browser. Mozilla's Firefox browser is a very good alternative.

As stated earlier, I build and maintain websites. On this machine I have been using Chrome as default, Chrome Canary build for some purposes, Firefox also and IE9. I have three computers here in my network, all with dual monitors. Using a KVM switch and Synergy, I flip back and forth between them all. Opera and Safari are on also on these other boxes. Mainly I set up the system to view websites that I control in different browsers so I know I haven't done something that looks goofy in one or the other. Point of fact, I rarely use IE except for this quality control purpose. I am a fan of Chrome with the single input box for search or URL. and for the way they take up little landscape.
Forgive me if I have given you too many questions and too many "I'd like to do it this way..." statements. Over the past days I have developed a trust in your advice/judgement.
And, again, thanks.

That sounds like a good combination. As the Malwarebytes staff told you, those two products should not conflict :wink:. I know of many who use Malwarebytes in conjunction with another antivirus, such as Avira or Avast, without any issues. :thumbsup:

You should be alright with MSE and Malwarebytes. Microsoft Security Essentials will provide you with the Anti-spyware support that you need. :wink:

You appear to have a pretty good grasp over what goes in and out of your computer :). The Windows 7 firewall is actually very good (light years ahead of the XP Firewall). However, it does not have HIPS, so you may want to consider using a HIPS-based firewall in addition to the Windows 7 one. In my opinion, HIPS is silghly over-rated. You seem to be keeping a close eye on your security settings, so I'd say you don't definitely need another firwall :wink:. Up to you, though.

On this machine I have been using Chrome as default, Chrome Canary build for some purposes, Firefox also and IE9.

As long as you keep those browsers (and whatever plugins or addons you use for them) updated, you should be just fine. Normally we see people ask for help who use only IE6 or something like that, so for them, even using an older version of Mozilla would be a significant step up :P .


Forgive me if I have given you too many questions and too many "I'd like to do it this way..." statements. Over the past days I have developed a trust in your advice/judgement.


No worries, I understand. :) In fact, I am happy that you are especially interested in keeping your computer as safe as possible :wink:.


Let me know if you have any more questions or concerns, I'd be happy to answer them. :wink:
