Re: [PCWorks] A tip for stopping annoying harassing "slide-ups" (a kind of pop-up) immune to pop-up blockers

1. You just click "Add", then do it again and again for each
site.
2. Adding one to the hosts file totally blocks ALL and ANY
access, you can't even get to the site.
3. No, if it's in the hosts file it doesn't need to be in
Restricted Sites.
4. I'm not sure, theoretically only YOU can modify it (or
allow access to it) because it's read-only. Try and make a
change to it as-is and watch what happens, so yes, it's
read-only for a good reason. Many anti-malware programs will
lock it.....it could be it's not read-only by default, and
maybe SpyBot, Spyware Blaster or other may make it read-only, I
can't remember. Spyware Blaster will make encrypted backups of
it, and restore a backup if something screws it up. SpyBot
also makes backups and can restore them. I remember seeing
something like "Lock hosts file" on one of my anti-malware
programs, but I can't find it now on any of them. Spyware
Terminator has "Hosts intrusion prevention system". My AV
software "Kaspersky Internet Security" (KIS) won't allow ANY
changes to mine unless I allow it, so it protects me from it
getting changed without my permission.
5. Yes & yes, but if there's any entries in yours you may want
to see if they're in mine and if not, add them.
6. I've never seen nor heard of a firewall-alerted attack or
potential firewall-alerted attack that did anything to the
hosts file. It may exist, I've just never heard of it.
There's not much of a reason for a site to do that: if it's
listed in your hosts file, you can't even get to the site for
it to even try anything with your hosts file. A FW can block
that kind of access from a site or IP, but only if it's a
decent one. KIS that I use would prevent it. (It's also a
firewall and system-wide protection suite). There's much more
lucrative efficient things for malware to do to a PC than to
just modify the hosts file.
7. I'm checking into that now.
8. From the looks of it, it may update it and then saves the
previous one as a restorable backup, because I have a bunch of
them. FAIK it may not ever update the hosts file, I've never
checked. The backups created just could be periodical backups.
For it to be able to update the file that, it would have to be
able to override the PC's setting of read-only on the file. I
don't know if it can do that. The domains it puts in the hosts
file could be only put there just after you install it, and
tell it to add its list to your hosts file, and it may not be
updated again, and that may be when it makes it read-only. ?
If so, then it could have precedence over the read-only
setting, and be able to unlock it, update it, then lock it
back. But, I've never gotten any alert from KIS that it was
trying to do that.
I'm going to have to try and remember what I last added to my
hosts file, then watch for any SpyBot hosts file updates, then
see if what I added is still there.

This is a very useful and important tip, Clint. Thank you.
For those who are having difficulty finding it, the Restricted
Sites area
that Clint mentioned is located at Tools - Options - Security -
Restricted
Sites in my OE6.
Clint, I have a number of questions:
1. I see how to add a single line to the Restricted Sites, but
I do not see
how to add multiple lines. How is that done?
2. Please explain how the Hosts file is better than the
Restricted Sites -
or what is the difference between them.
3. Is there any advantage to having the restrictions in BOTH
the Restricted
Sites and the Hosts file?
4. Can't malware also unprotect the Hosts file (by removing the
Read Only
attribute) just as we humans can? Does the Read Only attribute
really add
protection?
5. Does your hosts.zip file include the Spybot items? Can I
just replace my
hosts file with yours?
6. Shouldn't a firewall block these intrusions from other
websites? If so,
shouldn't we be making changes in our firewalls?
7. Hugh recommended a different file. Is there a way to merge
your file,
Clint, with Hugh's?
8. When Spybot updates the Hosts file, does it just replace the
file? If so,
then any additions from Clint and/or Hugh and/or mvps will be
deleted.
