Hi AVG, How often does this regular scanning process that removes JavaScript Obfuscation take place? I got these warnings on my professional website 1 week now and I'd really want to get rid of them... Thanks

No-one has said was the threat actually is, or what it does rather. It would help me to decide what to do with such flagged threats in future. Thanks

Hello, I just wanted to clarify, JavaScript and Java are NOT the same language, and Most obfuscated JavaScript is NOT spam or malware. I am a web developer, and i obfuscate my JavaScript quite often for clients that do not want their source easily decoded (well, it is easily decoded but stumps most users). Java is a proprietary language, now-a-days the basis for Android devices. Java installed on your machine is not a threat and few viruses are written in Java. AVG would easily sniff out a Java virus. So all in all, don't freak out when you see a notification for Obfuscated JavaScript, 99% of the time, it's harmless!

THANK YOU for the super informational video... AVG has been on my computers for three years now [and I only began using/learning the world of computers 'n' technology 6 July 2009!!] ** Aren't JAVA & JavaScript one and th same thing? I thought JAVA was a computer language vital for the communication needs, ie., computer to computer, and so on...? I AM an intelligent and quick learning computer user who lives online and I've noticed there is one technological characteristic that not only stands out, but consistently and persistently repeats and repeats, which is: The More I Learn the Less I Know! Finally, I'll leave you with a plea requesting ANY advice you are able to supply with regards to the Java/JavaScript conflict. I only want to enable my two laptops to work in the best environment with the most efficient settings as well as apps, add-ons. etc,. they are capable of having... THANK YOU once again, *RDelight* [rdelight@ymail.com]

sarah, now what i would do is either download malwarebytes and run a full system scan or download rkill a small program which kills all running proscesses then run a scan with malwarebytes to kill the malware on your computer. Or if it gets really bad! i suggest getting some sort of rescue disk and cleaning ur computer

I currently can not download any security program onto the computer without the system telling me it contained a virus and was deleted. Any suggestions? Ran virus scan etc and have found nothing. Also, when I try to save something to desktop to manually install the program/s disappear as if I had not saved them. Also...purchased the 2012 internet security and when I loaded it to the system the system crashed. HELPPPPPPP

Try to keep a clean copy of all your files, and if you detect this threat, replace the infected files for your copy. If you are using a third part application, as Joomla, PrestaShop, or similar, keep it updated to evite intrusions that can modify your files.
