First, the safety pack. 3 apps I suggest to any and everyone for all around security.
( I would provide links but that would be too easy. You should research before you buy into whatever some jackass online says )
AntiVir
Lavasoft AdAware
Spybot: Search and Destroy
AntiVir is for viruses, Adaware for adware, and Spybot for spyware. Simple enough. Note that most adware/spyware removers actually cover BOTH spyware and adware, which holds true for the two I suggested here. However, having multiple spyware removers is good considering that you will often detect things with one that you will not find with another.
Of course, telling you which three you should use should immediately clue any savvy internet go-er into the fact that Im just another "lamer", as the kids say, and shouldnt be trusted because Ive only used that one app. So, instead of not really helping, Im going to actually try to help ( give it a try for once, message board contributors! ). An alternative to AntiVir is the wonderful open-source ClamWin. ClamWin has found viruses on my comp AntiVir hasnt ( and vice-versa ), but keep in mind a thorough ClamWin check takes a LOOONNNGG time compared to AntiVir ( and any other anti-virus ). ClamWin also gets NIGHTLY definition updates ( something Im not aware of with any other app ) and is supported by a LARGE community ( thanks to its open-source nature ).
Then theres WinPooch. While I havent exactly unlocked this programs vast potential, it has already helped me once or twice. WinPooch, which can be associated with ClamWin making both of them even more versatile, hooks Windows API ( read up on it, I barely understand it myself ) and allows you to stop viruses from making changes WHILE theyre making them. This is both good and bad. On one hand you have to be on-hand verify whether or not something is ACTUALLY a virus, otherwise Winpooch may stop something from happening that you WANT to happen. On the other, if you ARE on-hand and you verify something IS a virus, you are given the option of allowing the virus to THINK it successfuly completed what it was trying to do when in reality it failed and was sent a fake "message" telling it everything was fine. Unfortunetly, hooking APIs with WinPooch consumes sometimes fairly noticeable system resources ( the more functions hooked the more resources consumed ). Please note that WinPooch is for EXPERIANCED USERS ONLY. While you cant quite cause your system harm ( directly... ) you can do things you will wish you hadnt. To recap, for even more anti-malware versatility, try;
ClamWin
WinPooch -- EXPERIANCED USERS ONLY --
I hope this helps. And for those with decently powered computers, AntiVir and ClamWin will work without conflicting with each other ( something that commonly happens with other antivirus applications ), providing you with TWO very thorough databases with which to check your computer with.
PLEASE NOTE: Common pay antimalware applications, such as Norton and McAfee AntiVirus, tend to be CRAP. At my shop, we suggest people have Norton or McAfee ( whichever they may have ) REMOVED and replaced with these free apps. If you have either of these ( or any pay antivirus for that matter ) youll probably want to get rid of them. Period. Not only are they poor virus scanners, they also eat up more resources neccessary, especially since both Norton and McAfee have gone "Dell" on us and started packaging everything INCLUDING the kitchen sink into their products to "add value." Let me put it this way people: If value needs to be artifically "added" , well, that tells you something...
And then theres Hijack...
Hijack This! is a techies tool. You CAN cause damage to your system with Hijack. You can disable apps you actually want, forcing a reinstallation of the program, and you can cause your system to become HIGHLY unstable by toying with it. But if you dont know what youre doing, or youre only planning on posting the log for others to filter through ( a common practice and viable option ), DONT MESS WITH HIJACK. Im overexaggerating a little, as most techs do, but not much. If you want to kill a virus that the scanners cant defeat, Hijack This! is one of the few apps that will allow you to do so ( often in conjunction with other apps ). Look into it, if you trust yourself.
I hope this helps others, and I hope others will help me ( and other others ) by contributing to my post, in a productive matter, mind you. Enjoy!
