Yesterday I found my computer was infected with several variants of Vundo. I first became aware of a problem when my system ran sluggishly and internet windows with advertising came up randomly. I also got the extortion demands in internet windows for virus software. I believe I got this infection as a result of having an older version of Java on my computer. I believe it was version 1.4. Nevertheless, from reading the forums it was not the latest version.
I ran SuperAntiSpyware and tried to eliminate the virus. However, this did not work until I first uninstalled the old Java program. After I did this SuperAntiSpyware appeared to successfully remove the virus. I ran another SuperAntiSpyware scan and Vundo was not detected. I am not getting random internet pages with advertising anymore. However, I sense that there might still be some issues with Java. Some internet sites load very slowly or not at all.
My question is, should I download and install the newest version of Java (I believe version 1.6)? I was hopeful that this would ensure that Java is under proper control and will hopefully get me to running correctly again. Thank you for any information.
