or just download avast antivirus, it is really great.
i havent had any virus on this computer since i installed windows 7 on it.

i also can suggest you advanced system care, it removes malware on your computer and repairs errors

[url=http://www.malwarebytes.org/] Here's a really good virus protection, although there is a version you pay for the free version is good too. [/url] (it's also fairly easy to find serial code for the paid version, but I won't be providing that.)

[url=http://www.qfxsoftware.com/] Here's a link to a keyscrabbler, this should prevent a hacker who has keylogged you from getting any correct info on what you typed. [/url]
Note: Most keylogging are done through R.A.T.s, and they would still be able to get your PIC through a screen capture method, also if the hacker is smart enough he can disable the key scrabbler.

Your brain.

A good anti virus you should use is Avast!
and a spyware/malware scanner use Malwarebytes.
Having both causes no conflicts and protects you in many ways ;D
Also have CCleaner to clean the junk files from your computer before you log on and/or do a scan.

I use Microsoft Essential Security, it's free and it works pretty good o3o

You might have better luck asking this in the non-MS tech forum, too?

The hotspot shield method seems to work again. Try looking that up.
