Yes please

That took out several hidden chrome extensions… Have the alerts ceased ?
I started Chrome few times, so far no new alerts
If all is well tomorrow let me know and we will uninstall combofix
No new alerts since yesterday, not even one

Subject to no further problems
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean

Click Start then Run.
On Windows7 or Vista you may use Start Search field if Run is not available.
In the box copy/paste the following command:

Wait for the uninstall process to complete.
