Continusly attached by trojan virus JS:ProxyBancos-G[Trj]

Hello,

I have an acer PC with windows 8, 64 bit.

For more than 3 months now I’m constantly attacked by this virus : JS:ProxyBancos-G[Trj] . Every time that I connect my PC to the internet I receive notification from avast (linked in the description) which tells me that an attack has been blocked by JS:ProxyBancos-G[Trj] (every 10min when I’m connected to the web) or URL:MAL more rarerly.

I’ve tried the avast scans (both full scan and scan on startup) and Malewarebytes scan but they didn’t solve the problem. Sometimes they find some virus sometimes not but I still constantly receive notifications from avast. I’m afraid this virus can still me some personal data.

Do I need to format my PC?

Can someone help me?

Thanks a lot.

Federico

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

Ok I’ve done it.

How is your system running now?

Good, Avast doesn’t notify attacks anymore when I connect my PC to the internet.
Meanwhile, everytime I start google or every other online app I get notify that “WindowsFirewall has blocked the program” and I have to manually allow the program.
Is the virus still present?

The virus should not be present but your Firewall rules were reset so you may have to teach the firewall new rules. But once a program has been set up (manually) the rules should be saved so that you only have to do that once. Is this not the case?

Yes it’s correct. Thank you very much.
Can I delete the programs I’ve downloaded to eliminate the virus?

Best,
Federico

[b]@dbrisendine[/b] will remove all tools used when all is OK

If everything else if fine for you (Avast is running / scanning with no warnings, etc.) then I will remove our tools and get you on your way …

Clean up of Malware Removal Tools
Now that we are through using these tools, let’s clean them off your system so that should you ever need to have malware removed again (we hope not) fresh, updated copies will be downloaded.

[]Download Delfix from here to your desktop and double click it to start the program
[*]Ensure Remove disinfection tools is ticked
Also tick:
[
]Create registry backup
[*]Purge system restore

http://i1351.photobucket.com/albums/p785/dbreeze2/just%20stuff/DelFix%20Standard%20Selection_zpswethifs1.png

[*]Click Run
[*]The program will run for a few moments and then notepad will open with a log. Note: Please save this log first before rebooting your system (if asked to); DelFix does not save the log as it is trying to remove all traces of our work on your system. Please attach the log in your next reply.

You can delete any log files left on your desktop as these are no longer needed.

==Some Tools to consider to help keep your system safe ==

Unchecky is a small service that runs in the background to help keep those “extra toolbars” and tag along search engines from automatically installing. By automatically directing you to a custom install with all the options unchecked, only what you manually choose and confirm gets installed.

CryptoPrevent is a free program that prevents CryptoLocker / ransomware from infecting your PC by locking down the OS so the malware can not get a grip on your system. You can read the details about this program here.

Also, consider keeping MalwareBytes Antimalware in your arsenal of safe keeping programs. Use the free version (not the paid or trial version) and you won’t have a problem with your antivirus scanner program. Keep it updated and run a scan with it once a week.

Lastly, if you use Firefox as your main web browser, consider adding the NoScript and uBlock Origin add-ons to the browser to block scripting hijacks and remove unwanted ads from the pages you view.

I’ll leave this topic open for a few days so that if you have any questions you can come back here. Surf safe, my friend!!

Thank you!
