Hello, My computer has currently been infected with a virus - normally what's known as antivirus xp 2009. Through this thread http://forums.whatthetech.com/BSOD_c000021...ror_t96574.html which was extremely helpful, I've fixed it whenever my computer was infected before. But this time, it seems bit different. Well, I haven't gotten any BSOD but as soon as I login to my account, whilst loading, computer freezes up so I can't do anything about it (this is normal as it always happened when I got this type of virus before). So I went to safe mode and did what was instructed in that website - running MBAM and ComboFix etc. only that MBAM doesn't run. As well as every single virus scan program that I have. I click on it and it does nothing. So I searched this solution and tried doing #5 from this FAQ http://www.malwarebytes.org/forums/index.php?showtopic=10138 I tried the procexp and changed the name from MBAM to winlogon and ran it. It was running. So I clicked quick scan and it seemed to be scanning for few seconds when all of sudden, the MBAM window is gone. And when I try to run it again, I get the message that (it's not word by word as I'm translating from another language) "it's file / roots are no accessable because I don't have the previleges / rights." I've also tried rootrepeal but that also disappeared when I tried to scan (it does run at the beginning!) But as soon as I scan, it scans a bit then all of sudden the screen is gone and I get the above message about how I can't access even if I restart the computer. EDIT: Just noticed, it seems that whenever that error occurs, the interface icon is gone, replaced by a default icon similar to ones you get when you uninstall a program and the shortcut in desktop remains with an icon of a 'window bar' (?)... Ok it seems like after this error (meaning when the program tries to scan this virus), it counters this by putting the message about "it's file / roots are no accessable because I don't have the previleges / rights." So basically, it seem to put an error to it so I can't open the program again and scan... EDIT3: Ok, I've tried scanning this virus with different languaged virus program and it scanned the files but froze up half way through...now I can't run the program again (even if I restart)... looking at above, I repeated myself too much here but I'm hoping you guys get what it means... So I was wondering if there is ANYTHING I can do to fix this problem other than obviously to format. It seems like the virus is countering EVERYTHING I throw at it. I mean, if I can just scan and get rid of the virus, I think it's fixable as combofix does the job to replace the damaged system files. Note - I don't know if this is important but when all these weird security pop-up came up, the window security menu also came up and I selected from no-firewall to firewall, then my computer froze... just putting it out there if this was the reason because I've never touched / changed anything when I previously got this virus. Anyway, I did change the firewall setting back to no-firewall through safemode... EDIT2: This error came up when I turned on computer this morning through safe mode - "0x10003973" ('s) order has referenced "0x602c7572"'s memory. Memory cannot be "read" Press ok to close Press close to debug (This error is translate so it's not word by word error message" ) But after I restarted, I didn't get this message again... Anyway, thanks in advance, Please help as I've never ever seen a virus like this...and if I can and if it does work in safe mode, I'll try to hijackthis (though would it help if I do it in safe mode? I'm not sure...)... but other than that, I can't do any scanning or go to normal window mode... Thanks again.
