new worm?, avast doesn' know it
« on: December 25, 2009, 06:11:14 AM »
hi, at 1am this morning christmas day i got a worm on my computer after visiting a website (the page was down so throught nothing over it at first) i first noticed my avast mail protection was going crazy and saying it was scanning mail for 80% off for viagara, soon after my computer gave me a warning saying it is shutting down in 60 seconds
after it did this twice i pulled my internet cord out and avast told me a system32 driver file was infected with a worm, i have put the comp into a boot scan (2nd time now) but it doesn't seem to be removing it i also tried deleting it when the comp was active and it came back straight away

once my computer it off this bootscan i will try find out what the file name was for you and edit itinto this topic

Please if you have any suggestions i would like to hear them, i pretty much live on my computer so anything like this really puts my life to a halt, so any suggestions would be helpful

Hi, Markwest, welcome to the forum.
I'd try MBAM, get it (free version) from here. You will probably need to download the installer file using a good computer, then transfer it using a flash drive to the sick computer.
Install it and run a quick scan immediately. Tick everything it finds then click "remove selected". It may prompt to reboot to complete remval; do so immediately.
Please post the scan report.
If something was found and removed, reconnect your machine to the web, update MBAM and run another quick scan.

Later you will have to see what your email program was sending, and to who, and contact all of them and tell them to delete those mails unopened.

I actully happen to have it on my computer already will run it as soon as avast gets out of the boot scan though i do have some further info, it seems to be copying or protecting itself some how , i found stuff from both temp and restore in the avast chest when i woke up and saw the boot scan had finished, incudling also another virus that avast did reconqize, , but once again avast yelped at me to restart and boot scan it before i could look here on the forum, i will try the program though and see if it can clear it, though i'm not sure how i'd move the scan report over here onto the laptop

Edit: found the file it's infecting. System32\drivers\kpgmh.sys

edit 2: The MbAM found nothing infected though it's probaby well out of date, any other suggestions , avast does see to find the bug in the boot scan but it's back as soon as my computer loads up properly
 
thanks for the input and help, hopefully we can get this virus locked down before it hurts more people

OK. I'm 13 hours ahead of you if you're in England, so will be going sleep in a (very) few hours.

No Google hits for that file. That's suspicious. It's probably a new malware variant, or if you're really unlucky, a trojan variant that keeps changing its name.

Can you please post the MBAM log.
If there is more than one, post them, in order.

Run MBAM again and this time when the scan is complete, all detections should have a check mark in the box to the left of the entry, leave them selected (or select if not selected). At the bottom of the window there is a button, Remove Selected, click that and the items will be removed.

Might be a good idea to update MBAM, too.
Your database is out of date, current version (as of yesterday) 3423. Yours indicates 3289.

If MBAM prompts for a reboot to complete removal (unlikely in this case, I believe, but possible) please reboot promptly.
