Can't find malware infection

system · August 19, 2012, 6:13pm

Every time I visit a search engine and do a search avast gives me a warning that Malware has been blocked. I’ve run avast!, MalwareBytes, and a couple of other malware scanners and none of them can find the infection.

The 2 logs from OTL are attached.

Woops. Here they are.

system · August 19, 2012, 11:03pm

So…what do I need to do now?

Pondus · August 19, 2012, 11:14pm

be patient…as all the removal experts are in bed now

OBS…your malwarebytes was not updated when you did the scan …always hit the update button before you scan ?
no need to post a new log if it is clean

There may be some delay due to differing time zones and availability of the volunteer malware removal specialists.
