Maybe it's your computer. Perhaps consider running a virus/malware/adware scan to make sure you have nothing on your pc that could be infecting your files.
I'd say backup all your files from your website, put them in a zip or rar archive and then on another pc/usb-stick/cd with a backup from your pc. Then scan your whole pc with a virusscanner (avg is a good one), ad-aware and then scan all files in the zip/rar file from your website (good scanners can scan these files without you having to unpack them). If you cleaned it all update all the code on your website to the newest version and if you wrote anything yourself check it for bugs.
Now this has come again...!!
Now the problem is that when i tried opening my website it didn't open and my system got stuck and suddenly switched off...!! And from then on whenever i tried opening my website my system got switched off..!! I tried in anther system in a cyber cafe and the same thing happened..!!
Then suddenly i remembered about this post here and checked for the website sourcecode and found the following unwanted codes in my web pages and when i removed these from the webpages my website came back into action as normal...!!
Now what i want to ask is How does this happen...?? As the previous poster SpellcasterDX said i too thought it would be my computer but when i scanned my system using Kaspersky Anti-Virus,it showed no virus or any sort of attack..!!
And the pages in which the codes entered showed they were last accessed on September 04 2008 at 4:32..!! But let me say i swear that at this time i waas sleeping (It is early morning in India at that time..) and didn't edit or access these files...!!
Then how did this happen..?? This is the fourth or fifth time it is happening in this sort to my website..!! Has this happened to any others' website..??
How to stop this from happening again..?? Please help me..!!
Oops i forgot to post the code which entered my webpages...!!! So i tried to post the code here..!! then it showed a 500 Internal Server Error..I don't know why this happened..!!
Hope to have a positive reply on my issue as soon as possible..!!
Are you using an up-to-date version of PHPBB?
It is possible that this keeps reoccuring to to a security flaw which is being exploited.
I think one of the scripts on your website got hacked. You should update them all, and maybe even dissable all till you are sure the script isn't the reason.
I removed the phpbb2 folder and deleted the database from my Direct Admin...!!
And today i found that there was a line in the HEADER part of the web pages s the following...!!! I am damn sure that i didn't put it...!!!
The line was:
How is that..???
it has to be something in your dir/account because you are the only one with this problem (for as far as I know), I don't know what you did but the only thing an admin could do is reset your whole account (or spend a lot of time on looking through all the scripts).
So if you want it reset pm an admin, else try looking through all your scripts, your chmods and the users with more than reading permissions.
I don't wish to cause any sort of difficulties to any admins by asking them to see through the codes...!!So i am ready to start afresh...!!
Please reset my whole account as soon as possible so that i can start work on my new website as soon as possible...!!
Thank you sir... I will start the work as soon as possible...!!
