Why did your IT guy at work recommend installing Hijack This? Are you having problems with your computer that may be a result of malware? HijackThis is an advanced tool, and therefore requires advanced knowledge about Windows and operating systems in general. If you delete items that it shows, without knowing what they are, it can lead to other problems such as your Internet no longer working or problems with running Windows itself. You should also attempt to clean the Spyware/Hijacker/Trojan with all other methods before using HijackThis. If you allow HijackThis to remove entries before another removal tool scans your computer, the files from the Hijacker/Spyware will still be left on your computer and future removal tools will not be able to find them. If you do not have advanced knowledge about computers you should NOT fix entries using HijackThis without consulting an expert on using this program.
With that being said, there are a lot of choices when it comes to computer security. For firewall and antivirus, you have to find something that works for you, something that you can understand and are comfortable with. Most important, it has to play nice with your system. What works well for my computer may not work for yours.
You will need a firewall. If you don't have one yet, check to make sure the Windows firewall is turned on. You can do this from Start menu/Control Panel/Windows firewall. Not having a firewall is just asking for trouble.
There are some excellent free programs available. There is a list of these programs in the page linked to below:
Also look at the spyware removal section-a list of programs is included.http://www.bleepingcomputer.com/forums/topic3616.html
