Viruses and worms

Hello all,

this is my first post and after reading a bit of what you do here and how you do it, I can only congratulate you and thank you for helping.

About my problem: Avast is detecting and sending to quarantene a trojan, w32:BitCoinMiner-JC(Trj)

The place where it says it is located is on c:\users…\appdata\local\iswizard

Can you tell me how can I remove this?

Thank you very much.

Hello again!

I did as you asked and, until now, no alerts have came…do you think it is solved?

Thank you for everything!

PS- report attached

12

OK if all is well tomorrow let me know and I will tidy up :slight_smile:

13

Will do.

Thank you so much for your help. I would like to give back the help, but all I know about is aeroplanes, composites and cnc routers…if this community needs anything I can help, please drop me an email!

14

Hello again,

until now no warnings arose…I think it is solved :slight_smile: Thank you!

15

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

Clear Restore Points

Go Start > All Programmes > Accessories > System tools
Right click Disc Cleanup and select run as administrator
When it pops up at the first prompt select OK after it has done some calculations the tabs will appear
Select More Options tab
Press Sytem Restore and Shadow Copies Cleanup button

https://dl.dropbox.com/u/73555776/disc%20clean.JPG

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

http://img233.imageshack.us/img233/7729/mbamicontw5.gif
Malwarebytes.

Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

If you use on-line banking then as an added layer of protection install Trusteer Rapport

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
[*]Microsoft Windows Update
