Help needed: rootkits detected, can't get rid of them, logs corrupted

[Ladyssnake]

Recently, I have been getting ghost devices on my computer. An icon shows up in the notification area for a split second at a time showing a removable drive when there is no device attached. I detected and deleted several viruses in the last week using a nightly scheduled full system scan. The last 2 detected 3 rootkits, but I received error messages when attempting to repair, move to chest, or delete them.

Running Windows Vista 32 bit.

My system event log has been corrupted and shows nothing after 2009.

My task scheduler also gives an error message saying my task image is corrupt or has been tampered with.

Screenshots are attached. Please tell me how to get rid of these things. Thanks.

The bottom image is related to the McAfee update, so you still have that running on your system

Download and run the removal tool http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

Then see if you still get the same problems

Then run the logs as shown here http://forum.avast.com/index.php?topic=53253.0

Tried to follow your instructions, got the attached error.  Ghost drive is very active this evening,  shows as disk drive in location zero when I catch it.

If you could run OTL I will use that to remove the job

I think avast is finding something running in its sandbox...could clear the contents of avast sandbox and see what are results
