  • How to use avg function?

    - by Marcelo
    I'm new at php and mysql stuff and i'm trying to use an avg function but i don't know how to. I'm trying to do something like this: mysql_connect(localhost,$username,$password); @mysql_select_db($database) or die ("Did not connect to $database"); mysql_query("AVG(column1) FROM table1 ") or die(mysql_error()); mysql_close(); echo AVG(column1); (Q1)I'd like to see the value printed in the screen, but i'm getting nothing but an error message. How could I print this average on the screen ? (Q2)If I had a column month in my table1, how could I print the averages by the months ? Sorry for any bad English, and thanks for the attention.

    - by raja
    I have only one VPS with Windows Server 2008 R2 x64 and want to buy an Antivirus. I tried NOD32 but they do not give less than 5 users in business edition (I have only one server).

I have few website hosted on this server and user have ability to upload .jpg, .gif, .zip files in few of the folders. Apart from above two any other suggestions on Antivirus that works well on above configuration and available for only one user? Thanks

  • Recommend AntiVirus for Plesk 8.6.0 + CentOS 5

    - by cappuccino
    I am using a virtual server on Media Temple running CentOS 5 and Pleak 8.6.0, I have done all their security recommendations and more some, blocking everything except http and mail, string passwords and running Rootkit Hunter daily. But i'm thinking I should run a antivirus of some sort? I'm still new to Linux CentOS security so please forgive :)... Can you recommend a good antivirus/antispyware software for CentOS 5 and Plesk 8.6.0? I've been searching for some plesk modules and have come across a few like Kaspersky, not sure which one to use... Any tips on security would be good too.

  • IE 9 home page is hijacked by avg

    - by horace
    I definitely know how to change the home page in Internet Explorer (Tools -> Options -> General). The problem is, no matter what I put there, it never changes. Stop/restart Internet Explorer and the old home page is back. I did some research to see if there is a registry key that I could tweak to get the home page to set properly. I changed the start page registry key and refreshed the view and the start page key (without even restarting regedit) was reset back to its original value. Now I'm a little concerned. Maybe there's some virus I can't detect on my system? Internet Explorer 9.0.8112.16421 Windows 7 Pro SP 1 x64

    I have a table named Student as followed: CREATE TABLE "STUDENT" ( "ID" NUMBER(*,0), "NAME" VARCHAR2(20), "AGE" NUMBER(*,0), "CITY" VARCHAR2(20), PRIMARY KEY ("ID") ENABLE ) I am trying to get all the records of the students having a larger age than the average age. This is what I tried: SELECT * FROM student WHERE age > AVG(age) and SELECT * FROM student HAVING age > AVG(age) Both ways did not work!

  • Symantec Antivirus Corporate -- two problems

    - by Alex C.
    We have a Windows network with a domain and about 50 clients. A few months ago, we installed Symantec Antivirus, Corporate Edition ver. 10.1.8.8000. There are two problems. The larger problem is that the software isn't very good at stopping viruses. In the last month, four different machines have become infected with those viruses that masquerade as antivirus software. Two machines I was able to clean with MalWareBytes. The other two were hopeless, and I had to reinstall Windows. Is there something I can do to make the Symantec product more effective? As far as I can tell, it successfully updates definitions nightly and pushes the definitions to the clients. The smaller problem is that the Symantec client applications sometimes initiate scans at random (and inappropriate) times. One of my co-workers complained to me yesterday that her computer was running very slow. I looked at the scan history and found that Symantec had scanned the computer three times during the past two days, and each time during the workday. No threats were found. Not sure why it's doing this, but I'd like it to stop. Any help would be appreciated. Thanks.

  • Should EICAR be updated to test the revision of Antivirus system?

    - by makerofthings7
    I'm posting this here since programmers write viruses, and AV software. They also have the best knowledge of heuristics and how AV systems work (cloaking etc). The EICAR test file was used to functionally test an antivirus system. As it stands today almost every AV system will flag EICAR as being a "test" virus. For more information on this historic test virus please click here. Currently the EICAR test file is only good for testing the presence of an AV solution, but it doesn't check for engine file or DAT file up-to-dateness. In other words, why do a functional test of a system that could have definition files that are more than 10 years old. With the increase of zero day threats it doesn't make much sense to functionally test your system using EICAR. That being said, I think EICAR needs to be updated/modified to be effective test that works in conjunction with an AV management solution. This question is about real world testing, without using live viruses... which is the intent of the original EICAR. That being said I'm proposing a new EICAR file format with the appendage of an XML blob that will conditionally cause the Antivirus engine to respond. X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-EXTENDED-ANTIVIRUS-TEST-FILE!$H+H* <?xml version="1.0"?> <engine-valid-from>2010-1-1Z</engine-valid-from> <signature-valid-from>2010-1-1Z</signature-valid-from> <authkey>MyTestKeyHere</authkey> In this sample, the antivirus engine would only alert on the EICAR file if both the signature or engine file is equal to or newer than the valid-from date. Also there is a passcode that will protect the usage of EICAR to the system administrator. If you have a backgound in "Test Driven Design" TDD for software you may get that all I'm doing is applying the principals of TDD to my infrastructure. Based on your experience and contacts how can I make this idea happen?

  • Comparison of Firewall, Intrusion Prevention, Detection and Antivirus Technologies in Organizational

    - by Berkay
    in these days i'm reading about intrusion prevention/detection systems.When reading i really confused in some points. First, the firewall and antivirus technologies are known terms for years, however now IDS becomes popular. My question includes: in organizational network architectures when/where do we use these systems ? What are the benefits of using each ? Does Firewall contains all these others? If you give me some examples, it will help much. Thanks.

  • Antivirus and Content Management / Web Filtering

    - by Moif Murphy
    Hi, We currently use Net Intelligence for our Web Filtering and Antivirus. We're looking for an alternative and I was wondering what people here use? We have many mobile users who work away from the office and so we prefer something which includes a remote agent and a central management portal that we can customise and add our own rules etc. Also preferable is bundled anti virus. Any recommendations?

  • Disable logon protection for Rising Antivirus

    - by Magnetic_dud
    Hi, i am using Rising Antivirus, free version. It has many advanced functionalities, including a "logon protection" that assures the protection of the password, or pre-logon protection. Unfortunately, that disables remote desktop connection until an user has logged on. (user log on, disconnect, then you can connect) I hate this behaviour, someone knows how to disable this function? (ok, i could create a limited user that autologons and then autodisconnects, but i don't like this approach)

  • Least intrusive antivirus software for development PC?

    - by poppavein
    What is the least intrusive and most effective antivirus software for a Windows PC that is used for software development (lots of small files and lots of disk I/O)? The software should support running from the command line so that virus scan be included into the build process. Edit: I understand that prevention techniques work better than any antivirus, but the employer demands that commercial AV software be used in the development environment (looking a replacement for horrible Symantec Antivirus).

  • How to get infected with Antivirus 2010

    - by PHLiGHT
    I know that this is the exact oposite of the question most people ask as it is a royal pain to remove. I hope this isn't flagged as me wanting to infect other people. I know my mom almost installed it but it was running firefox so she unknowingly downloaded it 10 times but didn't install it. I have since deleted those files and have been wondering what to look out for on sites that carry the virus. I'd like to test out AV software in a VM environment. It has been getting past our AVG as of late. Thanks,

  • Squid Proxy Antivirus - Recommendations / Performance

    - by Jon Rhoades
    Due to our user's increasing expertise at downloading virus and the like, we are investigating adding Antivirus to our Squid proxy. A casual Google reveals several free and one paid: HAVP squid-vscan Viralator Safe Squid (commercial) None of the 'free' ones have reached v1 yet, nor do any inspire huge confidence form their websites (although of course I would rather they spent their time on the app rather than their website!). Does anybody have experience with any of these (or any other similar apps). If so are they suitable for a production network with 400ish concurrent users, and what sort of CPU/RAM requirements does it have?

  • AVG time spent on multiple rows SQL-server?

    - by seo20
    I have a table tblSequence with 3 cols in MS SQL: ID, IP, [Timestamp] Content could look like this: ID IP [Timestamp] -------------------------------------------------- 4347 62.107.95.103 2010-05-24 09:27:50.470 4346 62.107.95.103 2010-05-24 09:27:45.547 4345 62.107.95.103 2010-05-24 09:27:36.940 4344 62.107.95.103 2010-05-24 09:27:29.347 4343 62.107.95.103 2010-05-24 09:27:12.080 ID is unique, there can be n number of IP's. Would like to calculate the average time spent per IP. in a single row Know you can do something like this: SELECT CAST(AVG(CAST(MyTable.MyDateTimeFinish - MyTable.MyDateTimeStart AS float)) AS datetime) But how on earth do I find the first and last entry of my unique IP row so I can have a start and finish time? I'M stuck. Would like to calculate the average time spent per IP. in a single row

  • Windows Server 2008 Antivirus Software with an API

    - by Dave Jellison
    I'm looking for an Antivirus package that is compliant with Windows Server 2008. That's not the hard part. What I need is an API layer on the Antivirus that i can call from managed .net code. For example: I am developing an Asp.Net (C#) website that allows users to upload files to the web server which the web site resides on. We have full control of the server so there are no security/rights issues on the server. I need to be able to run the antivirus algorithm on the newly uploaded files without (hopefully) shelling out to a command-ilne version of the software. Does anyone know of such a package?

  • Antivirus Configuration for dedicated SQL and dedicated IIS Servers

    - by Wayne Arthurton
    Our corporate standard is McAfee Enterprise, unfortunately this is non-negotiable. On two types of servers I'm responsible for, SQL & Web, we have noticed major performance issues with the corporate standard setup. Max scan time 45sec One policy for all processes Scan ALL files on write, read and open for backup Heuristics: Find unknown programs, trojans and macros Detect unwanted programs Exclude: EVT, LDF, LOG, MDF, VMD, , windows file protection) This of course still causes major slowdowns. IIS .NET recompiles are slow especially with SharePoint, SQL backups and restores, SQL Analysis Services, Integration Services and temp data from them as well. I have looked from time to time, for some best practices on setting up McAfee of SQL & SQL Analysis Service, SQL Integration Service, Visual Studio, Sharepoint, and .NET web servers in general. How do people setup McAfee enterprise on their corporate serves keeping security intact, but affecting performance as minimally as possible? Has anyone run across white papers on these setups? Obviously some are case by case, but there must be some best practices out there somewhere.

  • Ways to use ClamWin Antivirus

    - by Charles Gargent
    I dont use on On Access AV scanner, I just use Clamwin. My download manager invokes a scan on any files I download, and I dont share files. Apart from scheduling a system scan every week (seems an awful waste of resources) what other ways can I use Clamwin to keep your PC virus free. Ideas such as: scan files in open folders, adaptive batch scripts that scan most frequently used folders / last used folders things like that
