When your computer is already infected with viruses and malicious programs, it's sometimes irrelevant of what site you're on. You could be on the official site of Doctor Norton's Security Whatever and still new windows would pop up. So, it's very likely that this has nothing to do with you being on chess com.
Antivirus scans may not be sufficient in revealing what's causing this on your computer. I would try a scan with spybot, and more importantly, check my startup list.
I would like to call the attention of chess.com business operators to give feedback about this report/enquiry of mine.
To the one reading right now, BEWARE. DO NOT TRY TO VISIT THE LINKS BELOW. THEY WILL ATTACK YOUR PC WITH MALWARES OR VIRUSES!
While playing an online game here, suddenly I was forwarded to the URL below :
(Do not visit it! It will try to infect your PC with malware)
http://scaninternetworld.com <--infested!
Very shortly after, a new dialogue box pops up from the website saying, "Your PC is found infected with viruses. Press OK to start free scan to clean up..." ---DONT BE FOOLED! DONT PRESS OK BUTTON! NOR THE CANCEL BUTTON! You should ignore this by closing the dialogue box. Otherwise you have just given the website the access to download viruses to your PC!
Thank goodness I have an anti-virus software already installed in my PC, and it warned me about the attack attempt. But to be really sure they didn't actually infected my PC I ran a whole sytem scan. It took long hours last night to finish and thankfully nothing was infected. Relieved I call it a night after adding the website to my blocklisted sites in my browser.
This afternoon, went back here at chess.com, read a few article then went straight to playing my online games. And guess what! It happened again! But this time its from another website below:
(Do not visit it! It will try to infect your PC with malware)
http://cheapreadweb.com <----infested!
So now, can chess.com officials explain this occurences please. I have noticed you have ads here and there, especially those ones that pop up new windows. I can understand your need to have revenues but if you cannot control ads (or webpages we are forwarded to) that will attack our PC's, we would rather appreciate if you can just hold off such advertisements or applications that lead to PC attacks.
Would really appreciate an immediate investigation of the matter and regular posting of the progress and actions you will take on to get rid of these attacks.
Also to my fellow members, who have read this. Please let everybody know about my experience. There maybe others out there who had the same experience, and may be encouraged to voice out too. In that way, we can really know the real facts of these attacks. Let's also warn the others.
Thank you very much.
