Here's a recent review of antivirus software
AntiVir [Avira], which is free, tops the list, along with Kaspersky and Microsoft, which are not free.
I see nothing about PC-Total Guard, but it may be known by another name in it's paid version.
My opinion as to an AV's worth does not matter as long as it protects the OS without causing performance issues.
IF PC-Total Guard was installed when the trojan infested the system, then it's worth it's cost ...
nothing .
A worthwhile AV will at least notify about potential threats when you attempt to install 'questionable' software.
" Not doing any banking or anything. really the only things is MSN, facebook and browsing nothing else really. Does that mean they have my passwords? "
If I were you I'd change the passwords for MSN and Facebook. It's better to be safe than sorry and it's a trivial matter to change them.
Does the wireless router have a hardware firewall built in ? Check the manufacturer's User Guide or web site to see if it does.
Did you change the Username and Password when the wireless network was set up ?
Leaving the Default Username and Password as they are is not recommended as one can look them up on the net, if one chooses to.
Pick a secure password... one that contains Capital letters, numbers, and characters and is at least 8 letters/characters long.
