Title: pc infected (I don't know how...)
Post by: giannirusso on August 31, 2012, 06:48:44 PM
Hello, while I was browsing I get a virus because at the next boot I wasn't able to get network works correctly (plents of exclamation points).
First I tried to fix (I didn't understand) them reinstalling drivers then I tried run combofix and at the next boot I had network works correctly, except something remote access starts when I try to download files overs web sites.
I don't be sure that my pc is clean and I have seen your clean guide so I did run Malwarebytes, OTL, and aswMBR and I attached the log files.
Thank you for any help.
Gianni

This is the OTL and Combofix log. I have to disable the system restore point before to do something?
Thank you
Gianni

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

We will now confirm that your hidden files are set to that, as some of the tools I use will change that(http://users.telenet.be/bluepatchy/miekiemoes/images/javaicon.gif)   Your Java is out of date.
