Anyone caught this recently? Microsoft Security Essentials flagged and deleted it today on a full scan. Can't seem to find anything on their site or online that tells me exactly what it is.
MS says this:
Quote: |
Category: Trojan
Description: This program is dangerous and executes commands from an attacker.
Recommendation: Remove this software immediately.
Microsoft Security Essentials detected programs that may compromise your privacy or damage your computer. You can still access the files that these programs use without removing them (not recommended). To access these files, select the 'Allow' action and click 'Apply actions'. If this option is not available, log on as administrator or ask the local administrator for help.
Items:

It also gives this link, which says nothing:
This thing apparently got through to the system somehow before definitions were created for it a few days ago. I'll have to do some full scans on my other machines to see if it got through there, too. |

What kinds of websites do you even visit to contract viruses like this? My computers have always been virus free (and all I do is download stuff). |

That's what I was thinking. You're always on about viruses and anti-virus programs, Bass.
I don't think I've gotten a virus in about 7 years. |

One word: hanmail
Also, testing antivirus programs has become a hobby of sorts. Been spending a lot of time at antivirus test site forums. |

Shoot, when I moved in to my current place and got hooked up with that wonderful KT DSL with its mahhvelous 200kps connection, I got warnings of virus attacks every few minutes, until I finally blocked the messages. And I wasn't even logged in to anything, didn't even have a browser open.
I haven't gotten infected recently, but I've gotten warnings. And when I've been infected in the past, sometimes I've had to reinstall Windows. I remember one time when every time I hit a key, it was like a bullet hole appeared in the screen.
By the time you get infected, it's too late. Bassexpander is be commended for warning everyone. It sounds like it something in or transmitted through Java? So you need to keep your java up to date. And you think your school does????? Heck, I get Java messages all the time, and when I ask my co-teacher, all I get is a shrug. Since the computer is in Korean, I don't know what's going on.
You've got to have virus protection in Korea. And if you even use a USB key at work and then at home you are at risk. A lot of school computers are infected, partly because the public schools do not have DP people maintaining the computers, partly because most of the teachers are clueless, partly because updates aren't even turned on for many computers, and partly because Korean sites are often invasive. Oh, and because the kiddies sometimes get on to the computers and play games on sites that just love to do bad things to the computer. Don't let students touch your computer.
Not every antivirus program catches every threat. So you could have something lurking on your home or work computer and not even know it.
It's not just hanmail. I got an e-mail from a friend that looked suspicious. I didn't open it or respond to it because it looked like something had gotten ahold of his email list. He is not Korean, but is a foreigner, so he might have gotten infected through someone from his country.
Here's another way you can get suspicious e-mail. I got an e-mail recently that looked like a job offer. The person said they saw my resume on the internet. Sound familiar? A)There's sites that don't keep your personal info private. And B) There's sites that look like a recruiter, but aren't on the up and up, particularly offering jobs in China. Be careful!
As to the what kind of sites do you go to questions, I don't think it's the one's most people think of. I was looking at a site that offered a free download of some software, just give them your e-mail address. Looked a bit odd. The ringtone sites show up a lot on google warnings. Maybe avators, too? Seems to be the something for nothing syndrome.
Obviously, most sites are safe. But my point is the innocuous site you don't know could also be a problem. So everyone needs to be careful. |

I've got into the habit of installing free antivirus protection for people or computers I encounter that don't have it. My current favorite choice is Microsoft Security Essentials. A lot of Korean computers aren't updated to service pack 3 (or even 2) so it sometimes needs additional files loaded to run. Avast can also be downloaded (in Korean, which is kind of better) but Avast is only good for a year before re-registration. At least the new Avast has a very easy registration policy. You now click a button within the program to register, rather than messing with E-mail codes. |

I'm getting virus attack warning messages from Avast every few minutes again. It is a "DCOM exploit attack," and it lists the ip address of the source. I was getting them when I first moved in here and got this pathetically slow KT dsl connection.
Here's what one website says about the DCOM exploit attack:
Quote: |
The IP is not your internet provider, they are like you, a user on your
ISP's broadband.
If you 'whois' your own ip address it will not resolve to more than "Shaw
cable" either
That user is infected and attacking other accessible nodes.
That log entry shows at least that your prevention strategy is working.
either upgrade windows firewall to one that works in both directions, or
install a nat router between the cable modem and pc as earlier directed to
provide hardware protection. |
http://forums.techarena.in/security-home-users/494986.htm
So when a user has an infected machine, it can spread the infection to others connected to the IP, if they do not have anti-virus protection. And in Korea, there seems to be a higher likelihood of computer users who do not do Windows updates or have anti-virus programs. I've met Koreans who were totally clueless about these necessities.
What it also means is that if you do a fresh install of your OS, you MUST install an antivirus program before you connect to the internet for the first time to do updates. Apparently, you can be attacked without even going to a website (don't ask me how). Put Avast or some antivirus program on a disk or flash drive so you can put it on your computer without connecting to the internet. After you get Windows updated and programs installed, run a full anti-virus scan, and malware scan with malwarebytes.
I recently did a fresh OS install, and then hooked up to the internet to do Windows updates, etc., without putting Avast on first. When I did the malware scan, there were about 20 infections. I was able to remove them all, but decided to re-install. This time my full scan came up clean.
At work, my computer was infected with tons of malware and trojans. Malwarebytes removed them, without interfering with the Korean anti-virus program. |
