Ubuntu Security :: PC Defender 2010 Windows Virus?

Feb 28, 2011

I believe the name of the virus is "PC Defender 2010". This has self-installed, causing popups attempting to convince the user that there is a security flaw, and that they should upgrade to the advanced version. I have looked this up, and it is definitely a virus. The virus creates a shortcut with a target in the AppData folder named defender.exe. When I went to search for this file, after having set it to show hidden files and folder, I looked in the folder, and found nothing by the name of defender.exe. Does anyone have any ideas as to how to find this file, if it even exists, and then remove the virus all together from the computer. Ideally these solutions will be executable from Windows, as the user is rather afraid of linux.

Ubuntu Security :: WINDOWS - Iexplore.exe Virus

Sep 24, 2010

My machine that is running Windows XP got a virus a few months ago. Keep in mind I have NEVER used Internet Explorer.

Symptoms when CONNECTED to the internet: My volume is turned down on start-up. When the volume is on the internet explorer "clicking" noise plays frequently. In task manager there are two "iexplore.exe" processes running. As soon as I kill them they will start up again. They aren't taking up copious amounts of memory, but they are still very present. If left on for long enough pop-ups will start appearing.

Symptoms when NOT CONNECTED to the internet: None.

What I've done: I've ran a handful of the free Anti-Virus programs, e.g., AVG, ComboFix, avast!, and Malwarebytes' Anti-Malware.

Ubuntu Security :: Windows Virus Appears In Home Folder?

Jan 4, 2011

Lately, I've found 2-3 times an .exe file with a random name in my /home, and another data file with a random name as well. I'm a user of wine, but none of the programs that I use seems to be the cause. Last time it happened I sent it to virustotal.com, and this is the result: [URL].. So, this is clearly a virus. The two files show "nobody" in the proprietary field and "none" as group. What can I do to track down the cause? Also, telepathy-butterfly likes to hog 100% of CPU lately, and all I can do is killing it: is someone exploiting a vulnerability? if so, why the hell would he drop a win32 virus?

And if on uses windows use ZoneAlarm or Comodo has it does alot more than windows firewall and router firewall. Note the admin saying the other thread was why windows get more malware and not very much the subject of the thread to post there.

Ubuntu Security :: Virus Resides In The MBR And "rebuild" The MBR To Actually Remove The Virus?

Jul 15, 2010

I have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet removed the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU. Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus?

Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.

Security :: Security - Virus - Firewall Protection ?

Feb 23, 2011

I tried installing F-prot's linux scanner but it doesn't seem to want to install and I am tired of messing with it.

So I am wondering if I even need it or if there is something else.

I am behind a firewall already with my router if that helps any.

I guess I am having trouble understanding why virus protection is less necessary.

Ubuntu Security :: USB Flash Drive With A Virus

Jul 31, 2010

A while back I had been using ubuntu on a live cd after my windows partition had been taken over by a virus, which at the time I thought had been removed by my anti virus (and then took out winlogon) and I did a system repair instead of a complete reformat because I didn't want to lose all of my files. After repairing, I noticed some things like what looked like fake "this page has been blocked based on your security preferences" on major sites like ....., myspace and facebook. I ran another virus scan with a different AV and strangely it detected a behavioural software keylogger, which after looking it up seemed to be something that could only be installed with physical access to the system, which confused me. Anyway, this is when I started to use the live CD to copy some of my music, videos, pictures etc. onto my flash drive. From what I can remember, I used this USB on my main computer without problems, but the last time I used it (few months ago) I ran a virus scan afterwards, just to feel safe and it came up with a couple java exploit trojans. This was probably just coincidence and I hadn't ran a scan in a day or two, possibly even a false positive as I noticed no decrease to system performance or any odd happenings.

So, my questions are: Is it even possible for a virus from a windows partition to copy itself to a USB flash drive on an ubuntu live cd; and is it possible (if the virus was even capable of this) if I insert the flash drive into my ubuntu computer, it could do anything like transfer across my WLAN to my windows computer, or even copy its files onto ubuntu but be unable to do anything? Which brings me to another question: if I visit a website that may contain drive-by malware or a virus of any type, is it capable of acting at all, such as even trying to transfer itself into my home folder, or does it not even recognize ubuntu at all and do nothing?

Security :: 2010 CWE/SANS Top 25 Most Dangerous Programming Errors

Apr 7, 2010

The 2010 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most widespread and critical programming errors that can lead to serious software vulnerabilities. They are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all.

The Top 25 list is a tool for education and awareness to help programmers to prevent the kinds of vulnerabilities that plague the software industry, by identifying and avoiding all-too-common mistakes that occur before software is even shipped. Software customers can use the same list to help them to ask for more secure software. Researchers in software security can use the Top 25 to focus on a narrow but important subset of all known security weaknesses. Finally, software managers and CIOs can use the Top 25 list as a measuring stick of progress in their efforts to secure their software.

Ubuntu Security :: Trojan Virus Keeps Coming In Share Directory?

Sep 27, 2010

After some time i always see a trojan virus in my ubuntu machines shared folder. It is an exe detected by ClamAv as Trojan.Autokit-77 I thought i was getting it from some windows machine on the network but that isn't the case. I deleted the virus and removed my computer from the network and still the virus comes back. My computer however, is still connected to the internet through an independent mobile broadband usb stick.

So where is the virus coming from and why is it going to my shared folder. I thought ubuntu would not allow the virus to do something like this without me giving it permission. I am running 10.4.
