AVAST new update blocks the access to web.

Viruses and worms
1

after the automatic-update on the evening on 24-12-13 it blocks the web access.it also blocks adobe flash player as i wanted to install a new one and loosing my connection I couldn’t.I contacted with my isp-provider and he told me that he cannot <> my wireless network adapter as i was connected and maybe is a virus that hide it or the antivirus that block it.
I scanned my computer with avast and found BITCOIN-A [TROJAN], AGENT-BFV [EXPL], GEN.VARIANT.GRAFTOR 82095.
I cleaned them with avast and other malware trojan removals, i restarted my pc a lot of times and everytime i had access for 2-3 minutes at the beginning and then losing connection.
so 2 days have pasted and the problem persist.

2 hours ago i disabled avast and i had access to web pages.it also let me install adobe flash player.
i can also open pages using flash very fast.Please do something because this is not a solution.

i have windows 7 home edition 64 bit i
i have tried all the browsers opera,explorer,firefox,google,torch with the same result.
last 2 years i hadn’t any problem with the same avast-free editio

Read this topic, and attach the logs

And don’t worry if your ISP can’t see your wireless network adapter.
They are not supposed to see which one you have.

Thanks for fast response.I had already used some of these anti-malware programmes,I used them again with the order you said and now I am clean of viruses. With new update of avast 131228-1 (I had 131227-0 when i had the problem) maybe you fixed some issues, now I have no problem with web.
It is like before and maybe better.
Thanks a lot.
