AV Security infected computer; seems clean, need help for prevention

I need to know
a) how it got it, and more imporant,
b) how to prevent this again for the future.

Malwarebytes and MSE are really good (usually). The most common way for someone to get malware is by clicking a link to a website that is programmed to give a virus, or by opening 'bad' email. Internet Explorer 9 seems to be a bit better than other browsers (others may dispute this claim) because when something wants to download, it will straight ask if you are sure you want to download it. It has (if I may call it that) somewhat of an antivirus built in it. When Microsoft finds out about a 'bad' web address or common 'junk' emails full of spam and malware, and you click on it, IE9 will sometimes pop up a warning telling you if a web address or download is reportedly unsafe.

Also, whenever you are looking up a google search or reading your mail (or ANYTHING on the internet), be smart about what you click on. If you don't know who it is sending you mail, put it in the junk folder. If you don't know if a website is dangerous or not, be careful if you click on it. Google will recommend common websites at the top (after you perform a search) that are usually safe. read under the website description what the web address is. Safe browsing is your number 1 antivirus.

Make sure you do "full scans" with both malwarebytes and MSE. Some people may recommend a few other tools to make sure the virus is completely gone, but unfortunalty I am not familiar with those tools. Perhaps they can let you know what they are

Hi,

DustSailor has given you good advice. I would also recommend:

1. Scan your system with Microsoft Standalone System Sweeper:

2. Consider a paid version of Mlawarebytes - it has a very good malcious IP blocker that will automatically prevent you from stumbling onto known bad sites.

3. Consider installing a browser plugin that will help you identify potentially malicous Google serach links. There are many free plugins that do this. I use Norton Safe Web Lite.

You can also run an "online" scan with ESET .... this won't interfere with MSE or MBam;

1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
   ESET OnlineScan
2. Click the button.
3. For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
   1. Click on to download the ESET Smart Installer. Save it to your desktop.
   2. Double click on the icon on your desktop.
4. Check
5. Click the button.
6. Accept any security warnings from your browser.
7. Check
8. Push the Start button.
9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
10. When the scan completes, push
11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
12. Push the button.
13. Push

Run the recommeded stuff from the CD/USB/online scan first to make sure your system is clean - unless you do that first, anything you install to your PC will always be suspect.

Backdoor:Win32/Cycbot.G is a backdoor trojan that allows attackers unauthorized access and control of an affected computer. After a computer is infected, the trojan connects to a specific IRC server and joins a specific channel to receive commands from attackers. Commands can instruct the trojan to spread to other computers by scanning for network shares with weak passwords, exploiting Windows vulnerabilities, or possibly spreading through backdoor ports opened by other families of malicious software. The trojan may also allow attackers to perform other backdoor functions, such as launching denial of service (DoS) attacks and retrieving system information from infected computers.

Using a known 'clean computer', change ALL your passwords ... do not use the infected one to do this!

Flush the DNS cache and restore MS's Hosts file:

Copy and paste these lines in Note pad.
@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.
Right click on the flush.bat file to run it as Administrator. Your computer will reboot itself.

Ah, those get a lot of people.
Yes, be careful when you see something like that telling you you need to scan for viruses on the internet (after you've clicked your browser), OR any pop-ups that claim the same. You can go directly to a website that you know is a true antivirus to scan for viruses, but random websites or pop-ups should never be accepted. I would click log off if it happened (so it shuts down IE for you automatically) in the event i stumbled upon something like this (I have). Don't ever click okay, and sometimes clicking cancel is the smae as clicking okay.

PS. you should be able to save all open programs before you log off as nothing bad is downloaded until you accept it

However, do follow what Jacee said. This is a safe website scanner:

PPS. Why all of a sudden do I find like 10 posts from jacee that I want to rep, but can't because I have only recently repped her?
