MBR:Alureon and Krypric infection

Viruses and worms
1

Greetings,

earlier today while browsing Avast announced it an application is trying to run on my machine and after I instructed it to stop that, it announced it has detected MBR:Alureon. I ran Malwarebytes afterwards and got a lot of Trojans in the list. Told it to delete everything. Then ran OTL, saved log. And then ran aswMBR, saved log, but it also said it copied an MBR.dat on my desktop (which I don’t really understand).

Now, I have Avast running all the time and don’t go to dodgy sites, and I’m all in panic over so many found Trojans that I don’t even trust I got that sorted. From what I read the MBR:Alureon is a rootkit nastie and if I have this on my system it would still be there. I also found that Avast has put in the chest a nastie called Kryptic, three times at that.

I uploaded all log files and would be thankful if someone could look at them and advise me how to go about that further.
Thanks a lot!

It looks like all the bad stuff was in your sandbox - there is nothing apparent on your system from the logs

Are you experiencing any unusual behaviour ?

Thanks for having a look!
No, I’m not seeing anything strange taking place. In Avast’s chest there’s 3 times Win32:Kryptik-IBV[Trj]. No trace of anything called Alureon.

I also ran a full Avast check that came out negative so I hope I am clean now, but because I had a big load of detected infections by Malwarebytes that might have been there earlier without me (or Avast) noticing, I installed a script blocker plugin on FF and will try to work this way. Somehow those things have made it to the machine and I have no idea what else to do.

Thanks again for your help!

All the bad stuff was trapped in the sandbox and only two temporary files made it as far as your system ;D
