RE:ad.doubleclcik.net

Hi venus60
 
How are you doing?
 
I think that what you are seeing reporting sounds like it may be what we on the Community refer to as a PUA. (Potentially Unwanted Application).  Whilst not strictly speaking viruses these are very annoying at best in that they cause pop-up (as you have noticed) as well as in some cases redirecting your browser home page, and other behavior that may slow down the computer and direct ads your way, but they are not actually doing anything bad like damaging files or stealing information. Often they are installed intentionally by you the user as browser add-ons for various tasks such as quick search tools.. but they also come with the result of added annoying pop-ups and ads. Other times they 'piggy back' with other software that you installed, or try to 'sneak' onto your system entirely.
 
If you Google the phrase "ad.doubleclick.net" (keep the quotes) you will see many hits and links to other sites referring to this and offerring advice on removal.  This is such a common happening that we have a canned reply (thanks to @) that encapsulates the best advice and I have reproduced the salient points of it below for you to read through and then decide if you want to have a god at dealing with the peasky thing or if you prefer to contact good old Support for them to sort you out...so here goes:
 
"WSA does detect and remove many PUA's, and more are being added, but WSA does not detect all of them. A simple browser add-on with PUA behavior that is easy to identify and easy to remove is not likely to be detected and removed by WSA. Those that are intentionally difficult to locate and remove are. Please see THIS LINK for more information regarding Webroot's stance on these annoying programs.
 
For those that are not detected by WSA, please see this KB Article. It has some easy to follow directions on locating and removing PUA's. You may also want to submit a Trouble Ticket, especially if you cannot remove it easily from the directions in the KB Article.
 
For those that ARE detected by WSA, but cannot be removed automatically, you can submit a Trouble Ticket.  Webroot Support will help you get these annoying 'crapware' off your computer at no extra charge, and the additional examples may help to better automatic removal of that particular PUA for all users in the future.
 
To make sure that your WSA is checking for PUA's with the best proficiently, it sometimes helps to reset the PUA detection within WSA's settings. For PUA's that had previously been scanned and determined to be OK, but have since been added to detection/removal, you may want to complete the following steps:
 

• Open Webroot SecureAnywhere
• Click on ‘Advanced Settings’ from the top right
• Select ‘Scan Settings’ from the left side
• Unselect the option “Detect Potentially Unwanted Applications”
• Click on the Save button (you may have to enter in a CAPTCHA)
• Reselect the option to “Detect Potentially Unwanted Applications”
• Click on the Save button
• Run another scan with Webroot and remove any items that get detected.

To help avoid PUA's in the future, remember to read all of the information when installing or updating software (Adobe downloads often have those "extra special offers"attached... PUA'S!: often the PUA included will be mentioned, and you can opt out of installing it.  Those check boxes you see? Usually only one of them is for the User Agreement of the software you want, the others are for the junk you don't."
 
Well, hope this helps you both understand, and resolve the problem and if not please come back for further advice and guidance.
 
All the best, Baldrick
 
 

Hi venus60
 
You are most very welcome...I am so glad to hear that you have managed to resolve the issue...and kudos are of course due to @ for a most excellent and useful CR. :D
 
PUA are really pesky critters and the real issue is that it is so easy for them to onto one's system via downloads in which they are bundled, sometimes with no warning.
 
Just in case that is how your particular issue started I would recommend that for starters one always downloads software for the author's own website (unless they redirect one to another) and as the article stated...check the install options that are available doubly carefully...hopefully that will prevent the vast majority from slipping by.
 
Have a great weekend.
 
Regards, Baldrick
