Interesting… The GMER tool dies shortly after launching. The GMER site says some Malware will block it.

Michael, In order to analyze it please provide AVG with GMER (http://kb.avg.com/articles/en_US/How_to/GMER-Scan-Result/) and AVG scan result export (http://kb.avg.com/articles/en_US/How_to/AVG-scan-result-export/).

AVG Internet Security 2014 installed
For last week Explorer periodically uses up memory and CPU goes crazy.
Occasionally AVG reports blocking a Java Exploit even if no browsing is going on
Daily Scheduled and manual scan reports nothing.
Microsoft Malicious Software Removal reports nothing.
Event log shows

  • Lots Warnings for name resolution failures for "DNS Client Events". Lots of different sites.
  • Errors for Schannel

Started shortly after opening a link posted by a friend. On opening site it was clearly malevolent so I immediately killed browser. 

How do I eliminate whatever is doing this?
