1.Have installed ubuntu 10.04 on 2 pc's both run xp on 1 pc boot up selects xp the other selects ubuntu as the first choice. Why?
2.How do I uninstall ubuntu, and what effect will it have on xp ( both imported xp documents and settings ).
3.Do I need an antivirus or spam/malware filter?
I want to read my emails locally using Evolution & Thunderbird or some other mail client. I have bought a new domain and would want incoming emails sent to this domain ids to be scanned by a virus scanner & spam filter.I have read that MailScanner + SpamAssasin is a good combination/option. Are there any others for my requirement.I am not a Linux/Ubuntu expert - so a detailed step by step tutorial to set this up is what i am looking for.I am using Ubuntu 10.04 home user.
View 2 Replies View RelatedWe operate a small ISP and are currently using a debian distro as our gateway server.Recently we have had an increased number of spam issues with customers (not them sending it directly, rather the customer getting infected with a virus/malware and then their computer becoming a bot).I'd like to set up another gateway of sorts to sit after our authentication gateway but before our backbone to provide spam filtering (and hopefully virus filtering) for any traffic passing through which might be email.I've tried searching for any linux based software which would suit, but I'm coming up empty.
Surely there's something already out there which can perform this task.Finally, just to clarify, I'm not talking about spam filtering for email accounts we host ourselves (this is built into our mail server); I'm talking about spam originating from customers PC's which is passing through our gateway (but not our mail server).
I have a system running at home that uses Getmail to retrieve mail from my ISP's pop server. Dovecot then offers that mail over IMAPs to my desktops running Thunderbird.
The reason I have resorted to using Getmail is because I don't have a static IP (from my ISP) for my server, and thus this server doesn't act as an MX.
I have implemented Spamassassin in my Getmail script as described here.
From further research, I understand that in order to fully utilize Spamassassin 's potential, I have to resort to training it with SA learn.
Currently I still receive spam messages, but 50% of spam is marked as ****SPAM****, and the other half is not marked at all.
My question is this:
1) How do I get getmail to move messages marked as spam by spamassasin to be moved to a JUNK folder within my mailbox automatically?
2) I thought of creating a folder where my users can move messages they deem to be spam, and set up a crontab script to invoke salearn regularly on this folder to get the bayes engine to learn from it. Is this the correct way of doing it?
I am new comer in this forum and the beginner on freeBsdI have a problem on how to implement the spam filter program on mail server, the problem is i have no idea on how to implement and test the spam filter program on the mail server and where should i put the program? is it in pop3?

View 3 Replies View RelatedI used Avast webfilter (proxied webtraffic through Avast) when running Windows. Sometimes Avast would alert and "protect" me from being infected by a compromised website. NOTE: Avast would alert even absent clicking any links. Just viewing the page could result in infection. Should I be running some kind of proxy webfilter for protection? My understanding is that Firefox can be compromised and this can in turn compromise Ubuntu.Are these kinds of threats specific to Windows running Firefox, or Firefox per se. If Firefox per se it seems like I need some sort of Proxy webfiltering like Avast provides.

I am using CentOS 5.3. I was half way through that and got an email that had ***SPAM*** in the subject. Haven't received any more. First of all I want to know if spam will still get delivered, and just have a modified subject. Second, I want to know how to set it up so Spam goes to a user's spam mailbox (Virtual Users). And third of all, is it possible to disable spam filtering on a user basis, preferably using MySQL tables? Is it possible for users to mark a message as spam, and all further messages sent from that address will be sent to spam folder but only for that user?
EDIT: Yes spam is getting delivered with a modified header, on the server site, how can i deliver to spam folder? how to create IMAP virtual mailboxes on request without having to send an email to them first? Using virtual users with Courier Imap
I currently have the following email server set up:
Postfix with mysql backend
Dovecot
clamav
spamassassin
amavisd
And it all works great. However I would like it for amavisd to forward all the marked spam into a folder on each user account, but I cannot figure this out.
i know linux is very unlikely to get viruses and malware, but what about trojans?
View 9 Replies View RelatedCan a virus survive a reformat, running bootrec /fixmbr (both from the install CD), and then installing Ubuntu? Reformat meaning from the windows disk recovery console, using the format command for all partitions. Likewise, would a virus be capable of surviving just the first two steps alone without installing Ubuntu, just re-installing windows?
If one were to have an MBR virus on Windows or Linux, how abouts would you find or remove it without doing an entire disk wipe? And before someone goes "Linux is immune" take into consideration vulnerabilities on the user end.
I was on funnyjunk.com yesterday, looking at funny pictures. I clicked the next button, and a page popped up displaying that the website had malware hosted by hit.d1.net, however when I had Windows XP the MacAffee Siteadvisor Displayed that there was no malware. Is this Real or Fake? Just wondering if it is one of those fake spyware alerts, like from windows.

And does Factory Resetting or Hard Resetting clear all data on the device and reset it entirely? If so, how does that work? Is there a specific storage chip on the device that cannot be written to and only read for when a hard reset is requested?

So I downloaded a movie from megaupload and a pop up came up with [URL]....that bounced me to[URL]..but that webpage did not display.

View 9 Replies View RelatedIn Ubuntu 10.04 LTS, I have downloaded and installed texlive (2011). They have issued the following warnings:
1. "To the best of our knowledge, the core TEX programs themselves are (and always have been) extremely robust. However, the contributed programs in TEX Live may not reach the same level, despite everyone�s best efforts. As always, you should be careful when running programs on untrusted input; for maximum safety, use a new subdirectory."
What does this exactly mean? The installed program has already created own directories and subdirectories (e.g. /usr/local/texlive/2011/bin/i386-linux). Am I supposed to create a new subdirectory in home to write files and run latex program? Exactly how do I know that the downloaded and installed program is not malicious?
2. "Finally, TEX (and its companion programs) are able to write files when processing documents, a feature that can also be abused in a wide variety of ways. Again, processing unknown documents in a new subdirectory is the safest bet."
what is implied by "a feature that can also be abused in a wide variety of ways".
I have seen the light and will convert to Linux. I have booted this laptop from a CD with Ubuntu. The hard drive has been seized by a fake Window XP restore trojan(?), which sends all kinds of error messages and shows there are no files on the drive and no access to it. Using Ubuntu I can see everything is there.
Is there a way I can use Ubuntu and something like Malwarebytes to kill the malware on the drive? Then I believe I could back it up before I reformat it and bring it into the Linux world.
I realize that FF 3.6 was referred to near the end of this thread? Most Ubuntu based distros (Mint, Gosalia, Ubuntu, Xubuntu) are shipped with FF 3.5.8, are there any reported problems with this version of FF? Mint does offer Opera, I really don't care about installing Wine to gain access to IE6, you open the browser, there are two critical updates that shows, but on three occasions, I left the desktop for an hour, and the two updates still never applied. I have installed Clam AV, is there a malware scanner for Mint, too? I do want to be secure, but don't wish to run two AV's, have four separate malware scanners, and scan every piece of everything the way you must do in Windows. With Windows, you spend more time scanning than browsing. I don't want to have to do this with Mint, too.

View 2 Replies View RelatedI browse with Firefox and I had been running a pretty vanilla install of Ubuntu 10.4 (with a few things like tomcat and mysql) I supposed the repos kept everything (like java) up to date.
Some time ago I replaced OpenJDK with SunJDK.

A friend of mine was complaining about his Windows computer being slow here lately.
I told him he is probably full of malware that slipped past his anti-virus program.
I've heard that one can use a live Linux cd to remove malware from a windows computer. How would I go about doing this?
Is it as simple as booting the cd, then using zypper to install an anti-virus program to the ram file system and mounting/scanning the hard drive. If so what program is the best to use for this purpose?
A forum that I visit with Firefox has a message that says the following: Quote: I've detected a bestlifeusa.ru script that tries to run of this server, I've reported this, but I'm pretty sure most of you get this one too, I was just protected so I'm fine - you may not be so lucky, so I'm asking you guys to get your system checked immediately.
If you use firefox - install the No Script extention after you have cleaned your system for all worms, viruses and spyware. And make sure that the bestlifeusa.ru script can't execute on your system from this site. If you don't have any "anti script" "no script" "script stopping" system installed with your browser, you will likely not notice this script, I suspect it's a spy-script that spies on you - and you most certainly have it! I think the measures recommended might be Windows oriented.
I was thinking of physically removing the hard drive and use the computer only with a liveCD for security. But is disabling the hard drive in the cmos just as secure, or does software exist that can still access the hard drive?
