Firstly, xpAntiSpy has the AVG-AntiSpyware tweaks section included with it for free. Google for AntiSpy, as you can pick it up from anywhere.
Just don't remove support for Windows Product Activation like licdll.dll down the bottom and make sure you press Apply on the status bar.
Easy enough even for a techie to forget. No tweaks are happening!
I am fond of
PC Tools Internet Security and ThreatFire from the same site.
Includes Spyware Doctor.
Can be a pain to configure the firewall, so maybe a tech support person may need to come and help, use theirs or any specific or MSFN like forum.
Cost about $70 Australian Dollars together for one year, not sure if limits are placed on number of PCs. Not an Aussie product though, just use
Universal Currency Converter to convert their price into yours.
Make sure you run the free updated versions of the manual scanner/removal tools from the main commercial websites.
I don't mean buying their security stuff. And only use one real-time protector at a time.Ask for manual removal of infections without security software from these forums. If forum cannot be accessed then use a live Linux rescue CD
like Insert (60MB download - must burn ISO to CD the proper way) or use some other computer without infection. Insert has support for a Firefox
download through the right click menu. Might need some help with Fluxbox though. Ask through the Other Operating Systems though.
Can eliminate Windows malware without Windows. Gathers updates too, of course. Can be installed to a USB bootable storage device, and be copied straight
from slow Hard Disk to fast Memory.
Lastly, read software licence agreements to detect spyware or whether security software juristictions are up to the Romanian law courts like with BitDefender.
Most people cannot understand them, but their worth attempting to decipher the hidden traps.
If it says Free Software Foundation or freebie BSD licence, like with Firefox or OpenOffice or WINE for BSD, read these too, as many get frightened by security risks, plagirism, copyright infringement and believing FSF software is always free of charge.
