I scanned my Laptop and it appears that C:\Windows.old.000\users\Monskieth\AppData\Local\Temp\pavtmp & C:\Windows.old.000\Program Files\Data0.Net Software\Portable Antivirus is infected by a Win32:Malware-gen. How can i get rid of the virus? Is it safe to delete it? or is it a false positive?
hey i suggest you upload the file to virustotal.com and post the result here. otherwise you can try MBAB and or SAS and see what they come up with.

I don’t know what everyone is jumping up and down about if you look at the path to the infected file, you will see it appears to be something related to Panda AntiVirus (pavtmp) and a portable antivirus, see below. So far from being false positives, I believe the detections are good but on the unencrypted virus signatures of both.
{C:\Windows.old.000\users\Monskieth\AppData\Local\Temp\pavtmp
&
C:\Windows.old.000\Program Files\Data0.Net Software\Portable Antivirus}
So the questions are:
Have you installed a a portable antivirus (if so uninstall it as the signatures should be encrypted to prevent detection) ?
Have you used any Panda AntiVirus products ?

You have serious rootkit infection, HJT is no use to you. From your MBAM log C:\WINDOWS\system32\drivers\kbiwkmbpbpfqxy.sys (Rootkit.TDSS) → No action taken.
You should run Combofix and post the log. Follow all instructions carefully

Thank you for helping me

Combofix has removed the rootkit. Your pc has many infections.I would uninstall combofix now http://www.bleepingcomputer.com/forums/index.php?s=eab68518186b64fb0677524792426b02&showtopic=114269&view=findpost&p=650524
You should now run a full scan with MBAM, this time have it remove the threats it finds and post the log.
I would then reboot and run another scan with MBAM and see if anything removed first time, returns. Your pc is so infected, I am hoping Essexboy will look at your logs and comment,
I’ve tried it but, first, I accident installed combofix into desktop\Downloads. And I can’t uninstall the program. Then I type
CMD (enter)
C:\Documents and Settings\Dominic Nguyen>cd Desktop\Downloads
Desktop\Downloads\Combofix /u
enter
… And the combofix started to run scan and give me the log again
Please help
Hi
Let’s see if I can help a bit here. You still have some nasty infections.
We’ll use combofix again, but run it differently.
First locate combofix.exe on your desktop, right click it and select delete.
Download a new copy from one of these links and save it directly to your desktop. DO NOT run it yet.
It must be on your desktop, not in a folder on your desktop.
Please follow all previous instructions regarding security programs.

Hi
Ok, that explains what happene to some of those entries I had in the CFScript.
Let’s see if anything is left.
*Note
It is recommended to disable onboard antivirus program and antispyware programs while performing scans so there are no conflicts and it will speed up scan time.
Please don’t go surfing while your resident protection is disabled!
Once the scan is finished remember to re-enable your antivirus along with your antispyware programs.
Please go to Kaspersky website and perform an online antivirus scan.
[*]Read through the requirements and privacy statement and click on Accept button.
[*]It will start downloading and installing the scanner and virus definitions.

Thanks for waiting … I ran the Scan last night. And the electric shortage when about finish, LOL. So, I have to run it again this morning.
