Comment:
I was wondering how likely it is for trojans to be able to by pass a firewall. I would like to know what you think about this, happening from both "sides" of the firewall.
1.I've read that even if you do not actually choose to download something, a malicious user on another system could forcibly upload a program to your computer. Of course, there would need to be a vulnerable port open to the internet, from what I understand. When I go to grc.com and use shields up, my firewall passes all the tests perfectly. So, should I still worry about malware being shoved down my computer's throat? And what about malicious websites? How likely are you to get trojans or other malware by simply visiting a website? I'm not even talking about intentionally downloading any executables.
2. Now, about the other side of the firewall(host side). If for whatever reason, a trojan or other malware is on my computer, how likely is it that it can bypass my firewall from the inside and report other systems on the internet(sending a key log file to it's master, for example)?
Hi,XpUser and myself are not related in any way. You said I gave you a wrong recommendation in that other post? Are you talking about Spyware Terminator? If so, what problem are you having?
Hi XpUser4Real. Thanks for the reply, and sorry for mistaking the two of you.
Yes, the problem is in regards to Spyware Terminator. Or more specifically, the crawler toolbar that was installed with it(lol this happened over a month ago. That thread is old). You said on that old thread that I could have opted not to install the crawler toolbar. I believe you when you say that, so my mistake. I don't blame you for it. But anyway, I uninstalled the crawler toolbar that same day. I thought that got rid of everything, but apparently not. I made a new post about that(and several other issues): http://computing.net/security/wwwbo... Let me know what you think.

I uninstalled Spyware Terminator over a month ago lol. Right after I installed it, as a matter of fact. I'll check out Winpatrol. What is a BHO by the way?
Thanks

Well apparently my thread about the issue with crawler toolbar remnants(and other issues) was deleted and I have no idea why. Can any moderator please tell me what was wrong with that thread? The remnant from crawler is called CTun.exe and it keeps trying to run at startup but windows is blocking it.

Thanks XP4. I may send him a pm asking him why. Maybe the system deleted it automatically? Perhaps I am making too many threads/posts? lol
hey I was re-reading my "browser helper" post, and it would appear that it can be interpreted the wrong way. lol, like I am trying to make a gutter joke. but seriously, what is a browser helper? Why does my browser need help?

Your post was removed because you have made a great deal of postings in a short period of time. This isn't really allowed on the forum, especially if the postings are closely related. Try to combine similar problems if possible.
And thanks Justin for the explanation. I'll try to keep related issues in one thread. Should I make another thread of the one that was deleted, or just post it in this current existing thread that we are on right now? Or I could private message it to XP4 if that's okay with him.

Hey guys. Maybe someone can help me with this problem? One of the avast scans I ran on my computer came out okay(except that there were some files avast couldn't scan). Then a few hours later I ran another avast scan and avast said it detected a trojan. Here is the log entry:
Sign of "Win32:Adloader-JQ [Trj]" has been found in "C:\Windows\MEMORY.DMP" file. It chose to move the file to the virus chest. I don't know how my security could have been compromised between those scans. I am not quite sure what this memory.dmp file is. I don't know if it is saying a sign of a trojan was found in the file, or if the file itself is a trojan. Probably the former. From what little I've read, I think that memory.dmp is a common file created by windows. For logging crashes or something, right? Well, I had a major system crash/failure in between the time that I had the avast scans(the failure was during an ad-aware scan actually), so maybe windows created or modified a memory.dmp file, and avast misinterpreted it as indicating the presence of a trojan. Is that what happened? Also, should I be suspicious that this major system failure happened during my anti-spy scan with ad-aware? I got the BSOD and it said that windows has to shut down, and it just shut itself down and I was like ???
