I wrote this a while back. With the increase in Malware since the new year, and the majority of work I've been doing lately related to users downloading bogus (that's a good word) AntiVirus/Spyware programs, I thought I'd post this here.
-----------------------------------------------------------------------------------
As some of you know, I'm one of the not so common, lesser-boobied technicians. And due to utter boredom, the boss throwing a sickie and work being incredibly quiet, I'm scribbling a quick PC Health..anti virus.. antispyware..what not to do..sort of guide.
The most common, and sometimes expensive problem we seem to get in the shop is virus infected PCs. Often, the viruses themselves have been downloaded accidently by an overly eager user, who, having heard about the latest virus/spyware on the news, has decided to take things into his own hands. The problem is, for virus/spyware creators, these people are easy targets. They create software that sneaks into the system, installs itself, throws up a notice claiming that the system is infected (which, of course it is, but not in the way you'd guess) with a nasty virus, and if you send them money, they'll remove it. The most common, and hated of these is Winfixer. This program will throw up notice after notice, interrupting your browsing, slowing your PC to a crawl, until you a) Pay to remove it, b) Fix it yourself or c) Reinstall Windows. Another common program that works like this is Virus Burster, which not only tells you that you have a virus, but springs up porn popups for authenticity.
Virus removal currently starts at £35 in the shop that I work at, and goes from there. A format and reinstall is £45, and sometimes it's not worth fixing. It's an expensive lesson to learn, that some programs are bad, and
do not do what they say on the tin, but the complete opposite. I generally suggest that customers research software on google or the like, before installing anything.
This is what I use to keep machines healthy, it's all free, and I advise you do the same.
Step 1
Download CleanUp. This program is a nifty little utility which deletes temporary files, including things like cookies created during surfing. In deleting these files, it also removes 'tracking cookies', which are generally used to spy on you. It also saves a massive amount of diskspace, keeping your system running relatively smoothly.
Step 2
Download and install a free, legit. antivirus program. We like to use:
a) AVG, available at
AVG, by Grisoft.
b) Avast, available at
Avast, by Alwil software. Do not be put off by their mention of purchasing software. They DO provide a free version for home users, and this does require you to sign up and register.
c) AntiVir, available at
Antivir, by Avira.
Download only
one of these programs. Having more than one AntiVirus software installed can cause nasty conflicts and scary errors

Step 3
Download and install AdAware. I'll be honest, I don't trust other seemingly legit programs, e.g. Spybot. I haven't needed to use them, AdAware has always dealt with my spyware issues with no problems. It's easy to set up, configure and use, and most importantly, free.
Download Adaware
here. Run this every two or three weeks to keep your system clean.
Step 4
Every system gets a little untidy as files are constantly written to the hard drive. Defragging your drive can speed it up a lot. Windows has a built in defragger, which you can access by:
Start -> Programs -> Accessories -> System Tools.
Some people suggest using Diskeeper, available at
Diskeeper.com, but I haven't any personal experience with it, so I can't tell you if it works as well as the Windows Defragmenter, or if it's free. The Windows defragger has always been enough for me.
It's also advisable to run a checkdisk every few months, to fix any gremlins that have got into your drive. This is easy enough to do, although can take a while for larger drives.
Open My Computer. Right click on your hard drive, and click Properties. Click the Tools tab, and under Error Checking, select Check Now. I suggest ticking both boxes, and waiting through the possible reboot. Like defragmenting, this may take a while.
It's as easy as that really. Clean up, run antivirus, antispyware and defrag and checkdisk regularly. And it's great because it's all free.
Just be wary of what antivirus and antispyware programs you install, research everything thoroughly before installing it. Better to spend a little extra time reading up on it, than forty odd quid having it all fixed because you didn't.
