Something called dsserving-syscom appears to have installed itself on my machine. One of my favourite sites in particular has gotten very slow (haven't noticed problems on other sites) and on that site - Xpert Eleven, for those who also play/used to play - I sometimes see a pop-up prompting me to open or save something connected to this dsserving thing, which of course I haven't done. I've been recommended to download something called Spyhunter to get rid of it. Any comments?
