How do I stop this weird scan thing from hacking into my computer?

its calle Zentom System Guard

Zentom is malware that masquerades as anti-malware software. It will constantly complain that your computer has been compromised then offer to fix the problem if you pay to upgrade to their professional version. I got infected by a similar program called Spy Axe. I mistakenly installed this program thinking I was installing a missing Windows Media Player codec then it took over my machine. Norton, McAfee, Trend, and Spybot Search & Destory all failed to remove this malware. It was very tedious but eventually I was able to remove it by hand but a few times I almost gave up and just wiped the disk to install a clean system. My guess is that you downloaded an infected version of Open Office. Did you get your software from their official site? If not that is probably your problem. Otherwise you may have been tricked into installing it was a missing codec, Java update, etc.

does that mean i should delet the open office? and yes i did get it from the official site and how long does it take to get rid of?
