From: thanatoid on 28 Jul 2010 17:03 Well, it took almost 20 years but it finally happened. It's amazing what a small batch file (maybe not so small - it has vaporized... read on) can do. Those bored with my gargantuan posts can just skim over most of it (please read the SUMMARY paragraphs), but I would really appreciate specific answers to the four numbered questions, as well as general advice. (My KF is disabled, so go for it, denizens of aforementioned ;-) Using Compaq EVO-D510 SFF. One 80GB HD, one CD burner, a riser card with two horizontal PCI slots, and (re: a post from a couple of months ago) the Compaq BIOS does not allow for more than one device per IDE channel, I checked - relevance below. I was running 98SELite, as always, using Opera, on two or three sites requiring javascript etc. - otherwise I would have been using OffByOne and this /probably/ would NOT have happened. The firewall was on, of course, but the ESET internet monitor/file monitor were /not/, as I do not believe that is REALLY necessary - I /may/ have to reconsider that position ;-[ Script sentry was on, but it does nothing with batch files, just scripts of all kinds. And it works great. >>>SUMMARY (2 paragraphs) So, everything was fine, when all of a sudden my mouse and keyboard became possessed. Basically, it was like the left and right mouse buttons and Ctl and Alt keys were being randomly activated, FAST. I turned off the ADSL modem, and ran TaskInfo. There was a batch file in my temp (either c:\temp or C:\win\temp) directory which was NOT supposed to be there. It was running. I shut down the machine. I can't remember the file's exact name, but it was short, 5 or so letters, no weird numbers or figures. Boring (yet important if you don't want to ask about stuff I *already DID*) details: When I restarted, the same thing was happening. (And it remains the current situation, although one might say the virus is /less active/ than it was (as if it had a built-in downward slope). But the machine is unusable, plus, while the virus appears fairly non-malignant, just annoying (ALL user control is NOT affected, you just have to click and move the mouse a lot - and fast, to get in between the virus activity bursts) - who knows what it will do next? So far my data appears intact [AOT the system] but FUD are definitely having a big party at the lair of thanatoid at the moment. So after the reboot, I ran TaskInfo again - no batch file running. I searched for batch files on the C: drive and only found the few I wrote myself and have always had. /Nothing new./ I ran Restoration (still the only undelete program that is not 5-20 MB and actually works BETTER than any of /those/), searching for a bat file, nothing. I thought the file might have deleted itself after doing whatever it was supposed to do. It must have, since it is NOWHERE to be found, deleted or present. I rebooted, deleted the swap file in DOS, and rebooted again. Virus still active. I thought, OK, I'll reboot to XP - XP should be OK, right? Same thing. Then I realized XP reads several files on C. Then I tried to boot Damn Small Linux into memory, it would not (I /have/ successfully run it in the past). I went back to 98, and, since I just happened to update the ESET NOD32 signatures a couple of hours earlier, I ran it. The virus seemed to be paused by ESET running, but while ESET scans boot sectors and all memory, as well as everything else, it found nothing. I went back to XP and ran MalwareBytes Anti-Malware (or whatever it's called - I only see 8.3 names now...) - nothing on either C: or the XP partition. While running MBAM, virus activity appeared to pause as well. To make a long story a /little/ shorter, I removed the battery, cleared the CMOS (several times, different hard- and soft- methods), first restored an old saved MBR, then (when that did not help) created a new MBR, and finally restored an Acronis image after moving current C: data to another partition. I should mention that the virus /appears/ inactive in DOS. Well, who knows - but nothing weird /seems/ to be happening AFAICT. Well, when the restored Acronis image (which I believe contains the MBR in the first sector - I am extremely ignorant about some basics) exhibited exactly the same behavior, I started thinking WHAT the damn thing could have infected ELSEWHERE than the HD... Unless it is hidden /somewhere/ and fucks up the MBR every time I boot - I don't know much about viruses and what they are capable of. I tried Damn Small Linux again - this time it DID boot and ran in memory... Get ready for this... Sigh... DSL /appeared to exhibit/ - although to a CONSIDERABLY smaller degree - a little of the SAME behavior - a DOS-like window (whatever they're called in Linux) would highlight some lines of the window depending on mouse movement, and I /think/ a menu or two popped up without any clicking on my part. And the mouse appeared to be malfunctioning. (OTOH, having only ran DSL a couple of times before, and for a VERY short period of time, and already being in a somewhat altered state of mind, my perception /may/ have been mistaken - I don't know.) So... Having never had to deal with this kind of thing before (I got a virus in a POP email once, but it could not do anything, maybe because I had all scripting disabled at the time - it was hell to remove though), I thought the following: >>>QUESTION 1. It could not have messed up the processor - first, I do not believe that is /possible/, second, DOS seems to run fine. >>>QUESTION 2. AFAIK, the level1 and level2 caches clear upon a reboot, just like RAM does. I considered whether a batch file could alter properties of RAM and stay in it ANYWAY, but I do NOT believe that is possible. Also, there are NO RAM cleaning utilities on the Hiren's disk which would lead me to believe RAM is irrelevant as long as one reboots. >>>QUESTION 3. Since I wiped the CMOS/BIOS (I still do NOT understand the difference between them, although some people have tried to explain to me), and have restored (a few times) and then /written/ a new MBR, PLUS restored a perfect Acronis C: image, I have NO idea where this damn thing is living. I have the option of removing the CD burner, deleting all the root files on the /current/ booting 80GB drive ("drive Z") using XTreeGold, putting drive Z on the CD drive's IDE channel, and putting in my old 40GB ("drive X") on the other - booting - IDE channel. (I believe I don't have to physically move the Z drive, just deleting all c:\root files will make the machine boot from the X drive, but just in case...) BUT - since what is happening is quite inexplicable, I am afraid of contaminating my X drive. If the virus /is/ somewhere on the Z drive, and neither ESET nor AntiMalware can find it, I would imagine it is quite capable of infecting the X drive even if the computer boots from the X drive and the virus is somewhere on Z which one would /think/ would then just contain data - and a disabled OS (well, two disabled OS's 98SELite and XPSP3). Further infection /might not happen/ if I just use a LFN utility in DOS and copy stuff to the other HD, or copy to Flash drives using a DOS USB driver from Hiren's, but then again it MIGHT. IOW - ATM I am afraid to put the X drive on the other IDE channel or use Flash sticks. No one likes this kind of stuff, even I am no exception... I am VERY seriously considering running BeOS/Haiti or some Linux [for all internet access, but ultimately for everything, possibly] from a flash stick (fortunately, my BIOS allows booting from a USB device) but ATM I am not putting /anything/ in the possessed computer. [Although - apart from the indignity and misery of being screwed and humbled in my arrogance - I have really enjoyed being internet-free for a few days... Do y'all think internet use might be addictive? ;-#) (I spent an enjoyable 6 hours destroying a fourth old phone in two years while trying to fix it. Soldering isn't as easy at 55 as it was at 25... But getting soldering iron /burns/ sure is... Fortunately I know about the "run for the freezer and press the burn against something at -18� Celsius" instant cure.)] But I digress... I have /heard/ of viruses which resulted in "the entire computer going in the trash" but I am not ready to accept that - although I might /have/ to accept it /eventually/. >>>QUESTION 4: IF the infected computer /is/ history, and I build a new one and using a Linux version which can read FAT32 Windows partitions, copy various standard format data from the infected HD into Linux - I am risk free, aren't I? I am sorry this was so long but I thought I might as well provide ALL the information I could think of. I am writing this on my trusty 1997-built PI 166MHz running 95B and sending it via a 33.6 modem. I will do some Googling and look around some security sites but I thought I might as well humbly ask for suggestions. IOW...
