Yeah its already in plan and Sophos anti rootkit, Rootquest, and McAfee Stinger too. This thing has turned into a little antivirus test now. I have some interesting updates. Because of the unsuccessful scans i removed avira, and i am trying to scan different av-s. I already made a scan with AVG and Norton AV and both detected somthing, these were mainly tracking cookies what are unimportant, and i had 2 infected old archives too, what neither Avira, nor Nod was able to find, but these were not used for a long time, so these couldnt have been in connection with the current situation. Now i am testing avast! and it changed things a bit, from the very first moment.
When i tried to download it,i got an alert from comodo. I did not even download any portion of the installer in that moment, because chrome always asks a question before downloading an executable file, if i want to download it, and it places the download files only after that, so the alert couldnt have been related with the avast installer. It referred to a temp file, i was unable to make a screenshot from it, because the malware ruined my vga driver, and i got an error message from windows, that there was an error during the copy of the image from the clipboard, so i exported it to HTML, and this is what stands there:
12/28/2009 5:09:07 AM Detect D:\Documents and Settings\POK\Local Settings\Temp\175B.tmp UnclassifiedMalware@87633939 Success
I removed this temp file, and everything in that temp folder, and from that on the VGA driver works fine, that means i didnt had to reinstall it or anything like that, i just restarted the comp, and it worked well. But i didnt gave up the search, because i thought that i downloaded avast, and now i should do something with it so i gave the search a try.
And yeah it found a trojan on my Win7 drive( i was scanning on Xp ), in the pagefile:
As far as i remember, previous AV-s were unable to open this file, they said it was locked, although it couldnt have been locked, because the pagefile on both OS is restricted on the system drive, so it was not Xp-s pagefile, and so it couldnt have been used in that moment. I deleted the file, the scanner went on, and after 5-10 secs, i got blue screen
Regarding all of these this problem seems to be more serious that i thought, since my whole comp must be under control, and several av-s were fooled in this case, and it even managed to exploit avast the only av that could detect something so far.
About using several defense softwares at the same time i dont think it could cause such malfunctions. I have been using avira+spybot+comodo combo for years without any problem, and its quite useful, i detected many shrinkers with comodos av, that fooled avira during the scan. Aviras signature based scanner is one of the best, and that true for comodos heuristic guard, and of course i use it as a firewall mainly. Usually AV-s notify you during the install, if they find another incompatible product installed, and they dont let them install untill the incomatibility issue is present(like kaspersky for instance). And if a scanner is not in good relationship with another sw, you can alway turn it off during the scan, so they dont disturb each other.
