Revsci Cookie

by JannieB / August 16, 2006 1:11 AM PDT

Has anyone heard of / experienced this cookie? I believe it is a tracking cookie as everytime it shows up, I get a lot of junk emails. I have deleted it about 1,000 times over the last couple of months, and entered it in the block cookies list of IE. All that did was make it mutate to revsci[2]. There is a website for the company, Revenue Science.

It isn't caught by Adaware, Spywareblaster, Spybot, or Norton Antivirus, so any ideas would be greatly appreciated.

I have a Dell Dimension 4400 with windows 2000 professional, with administrator and user split. I use IE and Outlook Express. Please don't tell me the solution is to change to a different browswer as this is my work computer and that's not going to happen. Thank you for any ideas.

Revsci Cookie

Open Internet Explorer, go to Tools > Internet Options, click on the 'Delete Cookies' and 'Delete Files'. Choose to delete offline content on the prompt.

Did you happen to check your Tools|Privacy Advanced settings? And Tools|Privacy Sites?

Are any of the sites in your Trusted Sites list?

Do you have a HOSTS file?

I have deleted from internet options and the regular cookie folder too many times to count - makes no difference. Don't know how to access the trusted site or hosts file.

Trusted site

In reply to: revsci

On the Internet Explorer 6 Tools menu, click Internet Options.

Click the Security tab, and then click the security zone

Trusted sites

Regarding the HOSTS file - you will have to download it:

This download includes a simple batch file (mvps.bat) that will rename the existing HOSTS file to HOSTS.MVP then copy the included updated HOSTS file to the proper location. For more information please see the readme.txt included in the download.

pls. read more here: http://www.mvps.org/winhelp2002/hosts.htm

You also could BLOCK via:

Internet Explorer:
Go Tools->Internet Options->Privacy and click Sites. You can then add revsci.com and ads.revsci.net/adserver to your list of blocked sites so that cookies from that site are refused automatically. You can also click Advanced and have IE prompt you for each cookie that requests installation. Over a short period of time you can have a nice rule base set up for which cookies you do and do not want.

Go Tools->Options->Privacy->Cookies and click Exceptions. There you can add ther above to the block list. You can also select "ask me every time" and check "from originating site only" to have Firefox prompt you every time a new cookie requests permission just like with IE.

I also would suggest downloading and installing SpywareBlaster:

I checked my cookies folder and wouldn't you know it, I had to once again delete the revsci cookie! I had already entered revsci.com in the blocked cookies list, but I added ads.revsci... and we'll see if that helps.

I have spywareblaster installed, wouldn't operate a computer without it, but revsci doesn't appear in any of their lists. Don't know if this is new or what. I've only had it pop up in the last 2 or so months.

I haven't had a chance to review and try the hosts info, but I did print it out. I'm not very tech savvy, no formal computer training so I just muddle through. So I have to be very careful what I attempt to do.

Thank you for all of your suggestions. If it still keeps appearing after I try the Hosts info I'll post again. Thanks again!

Did you know

Did you know that this cookie comes from this website. I use the noscript extention and I do not allow revsi.net to script here.

Hope this helps.

No I didn't...

How would I do that?

C/NET - would you allow a tracking cookie on your website?

I also had NO idea, but ......

Marianna, have you been using NoScript for long? How do you like it?

I have been using NoScript
by PudgyOne / August 16, 2006 7:18 AM PDT
In reply to: NoScript

I have been using NoScript for some time. I really like it. I try NOT to allow scripting on any website, unless I have to. I at first temporaily allow if needed. If it's a website I frequent, I then tell it to allow but only for the main site I'm on, example, here I only allow CNET.com. I do NOT allow the rest of them to work. If you are downloading a file, you'll have to temporaily allow that site to allow scripting.

I can't be without this extention.

In reply to: revsci

I want to let you know that typing in the ads.revsci... in the cookies blocking option seems to have solved the problem - I haven't seen that cookie since! I didn't have to do anything with hosts files. Thank you for your help.
