Windows XP Trojan Question - Am I Safe Now?

[audiodrome]

Last Tuesday, my computer (Windows XP SP3) was infected and I thought I caught it in time but it must have downloaded to my computer somehow. It disabled my Firewall and my System Restore. I tried doing a System Restore but it wouldn't let me. Initially, Avast found a couple of files and deleted them but I negelected to write them down (I remember they were of the trojan-gen type). On Thursday night, I did another scan and it found six files in my System Restore folder all named Win32: Crypt-DGV [trj]. It said that it had successfully deleted them. I then ran some other spyware programs (Malwarebytes, Superantispyware, Ad-Aware, and a-Squared). Malwarebytes detected another bad file and deleted it. I also disabled the System Restore and did another scan to be safe and Avast found nothing.

So now it's been over four days since I got the initial infection and there haven't been anymore trojan files detected in my antivirus/antispyware scans - am I still vulnerable? Have there been instances of trojans hiding out for weeks or months with no symptoms or detection?

Assuming that these programs found the trojan files last week, you would think that if they came back, they would be able to find them again, correct? Or are these trojans able to mutate into files that then can't be detected by antivirus/antispyware? I realize that the viruses "out there" on the internet can change names and configurations and it's always possible to get infected again by clicking on questionable links and the like, but can those original trojans actually mutate into new, undetectable files later on down the line while they're in your computer?

Thanks!

Hi audiodrome,

Download hijackthis from here: http://www.filehippo.com/download_hijackthis/download/58170ee6e58bba306c943f5b6d745c99/
Be sure to download it to the desktop, and not into a temporary file. Do a full scan, and place the logfile.txt as an attached file to your next posting. Do not do anything else until told,

Thanks!

I wasn't sure how to attach it as a file so I copied and pasted it:

   Hi :

 I am unable from reading your Log as to IF you have Adobe Reader or any
 remnants from that program, but IF you do, I recommend you read
 http://forum.avast.com/index.php?topic=38839.0 ; Alternatives would be the
 FREE "Foxit Reader" or "CutePDF" .

 And having Lavasoft's Ad-Aware is not recommended, since it has an
 unnecessary "Service" running that can NOT be turned OFF .

I thought I had the latest version of Adobe Reader installed but I'll check that out. I wasn't aware of the Lavasoft issue. Should I uninstall it and just stick to the others? I'm not completely sold on it anyway. One other thing I have been concerned about is that I haven't received any automatic updates from Avast since the infection and I have both iAVS Update and Program Update set to "Automatic." I did a manual update yesterday but the fact that it wasn't automatic could just have been a timing issue.

Does the scan look OK otherwise?

Hi audiodrome,

Apparently you have no active firewall running there,

Thanks. When I check my Windows security settings, it says that the firewall is on! What's going on there? I already have Superantispyware on my computer so I will run that again now.

[audiodrome]

I ran the Superantispyware scan and it found 1039 "infected" files and they were all tracking cookies. I was told that you can ignore cookies because they aren't much of a risk. The last time I deleted all my cookies, it screwed up a lot of the websites that I visit on a regular basis. It won't let me post the whole list here because of the character limit. Do you need to see the whole thing? All of the remaining infected files are from C:\Documents and Settings\Sean\Cookies\

Needless to say, I didn't realize that I had this many cookies, but they are all quarantined now. The weird thing is that I just checked a couple of my regular websites and they all "remembered" me. I thought that if you remove all the cookies, you had to login from scratch.

Also, how do I fix the firewall problem with HijackThis? I've never used it before. I checked the box next to that line and hit "fix" and the window went blank. It didn't say "fixed" or anything like that. I then did another scan and it still said "no file." However, when I checked my security settings, it said that the firewall was on. How can it be that the HijackThis log says I have no active firewall but my Windows Security Center says that it’s on? Now I'm starting to get worried. I'm afraid that I deleted the firewall key from my registry. Either that or something really strange is going on!

[polonus]

Hi audiodrome,

Don't worry, we only did not detect an active software firewall, if you have the Windows fw running, no problem. The fix is for a file that has disappeared already, for the rest you are doing fine, so absolutely no reason to panic,

polonus

[audiodrome]

So I didn't change anything by fixing that line and everything else looks good? That's a relief - thanks!

How is it that those websites remembered me and I didn't have to log-in if I removed all the cookies? Or did it only quarantine the "bad" cookies?

[zone12]

Do a spybot S&D scan too

[audiodrome]

Thanks - Spybot looks like another good program. I ran the scan and all it found was 6 tracking cookies. It looks like I'm good for now!

So that just leaves one concern. I haven't received any automatic updates from Avast since the infection and I have both iAVS Update and Program Update set to "Automatic." I did a manual update yesterday but maybe it would have been done automatically if I had waited a little longer. Has there only been one update since New Year's Day?

This is what I currently have for Avast versions:

iAVS Version : 090104-0
Program Version: 4.8.1296

Lastly, is it worth doing an online scan?

   Hi :

 Sometimes malware can "hide" from a HijackThis scan UNLESS you "rename"
 "HijackThis.exe" to something else, like "humble.exe", then run another scan
 to see IF anything "different" appears in the Scan results !?

 And I always recommend "tracking/adware" cookies be immediately
 "deleted"; there is no need to "quarantine" cookies . Any safe site you visit on
 a regular basis should NOT be using "tracking" cookies, only the "regular" kind.
 With your cookie "problem", you should seriously consider installing the FREE
 "SpywareBlaster" from www.javacoolsoftware.com/spywareblaster.html ;
 there is a "Tutorial" on this program at
 www.bleepingcomputer.com/tutorials/tutorial49.html .

Thanks for the info. I'll try that and see what I get. One more question: is it necessary to have Java installed? I don't seemed to have it on my system - only the early Microsoft Java.
