So anyway, I've got this problem with my machine, some kind of malware - I guess really a trojan. It first started showing up a few days ago as a notification from Norton that there had been "an intrusion attempt by 873hgf7xx.com was blocked." It also says that no action is required and gives me an option to disable further notifications of this type, but 1) Norton doesn't usually throw up notifications like this and 2) I note that the attack is coming from the svchost.exe file in the system32 directory.
Like I said, I really don't know much about computers these days, but it seems to me that any intrusion attack that looks like it comes from within your own machine and wants to go outside is something that needs attention.
At about the same time this problem came up I started getting some ad that was trying to get me to sign up for something called antimalware. I closed it with alt-F4 but it kept coming back and I realized that it was somehow in my machine. I found this directory "C:\Documents and Settings\John\Application Data\DEC2EC89102A4ACF5286E49260D247AB\setupupdater0000.exe" - and I can't remember how I associated it with the antilmalware thing but anyway I deleted it and the popup stopped.
But the intrusion attempts continued. Sometimes from svchost.exe and sometimes from firefox.exe, and originating from four or five different filenames which reference ip's like 126.96.36.199, 443 and 188.8.131.52, 443 . I tried to find out where those are and they look like they're in eastern europe somewhere, I think.
I couldn't find any of the file names and this seemed serious enough that I took it to a tech here in town, but they don't seem to be able to take care of it. I contacted Norton and they were very little help, although they will work on it for $100 or so.
So I googled a little and found this and some other forums. Somewhere I ran across the idea of downloading TDSSKilller, and I ran that and it seems to have done something with mouclass.sys . I don't think it worked though, because Norton history shows that there was an attempt to remove a virus associate with that file and it failed. It also apparently recognizes mousclass.sys as a file that needs to be manually removed. There are some other suspicious files that Norton noted at one point in the history, but I can't retrieve them now.
In addtion, Norton itself is now behaving strangely. The SONAR system shows that it needs to be fixed but clicking the fix button doesn't work. At one point Norton offered another file for download that apparently was supposed to fix this. I ran it, and rebooted the machine as it requested, but after a few minutes the Norton icon showed a red cross on it that is the signal that something not so good is going on, and when I opened up the panel it showed the system is "at risk." and offered the fix which doesn't work again. At one point I noticed when I was opening the panel the SONAR - which is the portion that needs the fix - was turned off. I didn't turn it off, and I turned it back on. It turned itself off a few more times although now it seems to have stopped doing that.
I also ran Hitman 3.5 but it didn't detect anything. I'm at a loss as to what to do now, and I thought I'd try to get some help here before shelling out more money to Norton.
If this can be fixed with a minimum of pain then obviously that's what I'd like to do. If not, the computer tech I've already paid $75 to says they'll reformat the disk and reinstall windows for another $30. I'd just as soon do that, but I'm not sure that will take care of things anyway. Seems I remember something about viruses that hide on the boot sector of the disk - so that would let it reinfect I guess?
The main thing that concerns me is the security of this computer. I use it for banking and secure email and I can't afford to have either compromised. In it's present state is that a concern, as long as Norton is 'working', at least as well as it seems to be able to.
And on another note - Norton really doesn't impress me much. I used to use Kapersky, which was a lot more complicated but seemed more thorough. Any recommendaitons for an internet virus/security suite? Thanks much in advance. I can't figure out how to attach a file right now, so I haven't attached the log from TDDSSKiller, but I have it if that will help.
