2 things jump out
one a possible rootkit infection & 2 , you have java 7 installed and many sites just don't recognize java 7 and won't work with it and threy still only work with Java 6. u32
lets see if curing the rootkit will sort out the problem
step1.
Run tdss killer from
http://support.kaspersky.com/viruses/solutions?qid=208280684let it cure anything it fnds ( except SPTD.SYS or anything detected as UnsignedFile.Multi.Generic, which should be ignored) & then reboot
post back with its log
By default, the utility outputs the log into system disk (it is usually the disk with installed operating system, C:\) root folder.
Logs have names like: UtilityName.Version_Date_Time_log.txt.
E.g. C:\TDSSKiller.2.4.7_23.07.2010_15.31.43_log.txt
