Hi there

Feels kind of funny posting on a forum and asking for help when ive given nothing to the forum, but you guys seem to know whats what. So here i go.

a few week ago i started noticing DNS attack warnings on my laptop. Thought nothing of it as it appeared to be an internal ip.

My wife then started having trouble with her pc. Slow boot up, random crashes and lots of warnings from ESET about quarantined files. However on checking the log i can see these files have not been deleted.

The pc is running on Win 7 64 bit, on a dell with a q6300 and 4 gb of ram. ive tried booting in safe and running various anti malware etc to no joy.

Hope one of you can help!!!

Oh and ive also added a pic of the ESET log

Thanks

James
