what's the best free software to detect trojans on a computer?

Question

My Internet provider disconnected my service for excessive bandwidth usage, and because I only use my computer for normal tasks such as e-mail, and don't have wireless or excessive downloads, they suspect I might have a trojan. They have reconnected my service after I talked to them, but I need to find a good program to detect trojans because my Trend Micro isn't picking up anything. I tried Sana Security and nothing yet. Any suggestions or any other ideas on what could be causing my problem?

I already have Spybot and AdAware and they both pick up nothing on scans. I thought that was a little strange, because usually they pick up at least a couple things each time I scan.

Answer 1

Here you have some:

Answer 2

The two best programs I've ever used for this purpose are SpyBot Search & Destroy, and Ad-Aware. It really takes both, for they each find different things. They are free from download.com.
http://www.download.com/

After installing SpyBot, immunize the computer against over 16,000 known pieces of spyware. Then run a full bot check and remove everything it finds using the Fix Selected Problems tab. Keep it updated and run it weekly to keep your computer free of this stuff. I’ve used it for 3+ years and depend on it to find the stuff that hides in your computer and causes major problems.

Then run a full system scan in Ad-Aware and remove everything it finds. After that, run a smart scan daily, and you'll keep the trojans and spyware off your computer and keep you and your ISP a lot happier!

Answer 3

Use a firewall

try reinstalling the OS

Also check if somebody else (friend/relative) is using your connection to download big files (movies etc) or using P2P etc

Also change your ISP. Read the fine print . If you have no download limit they should not be complaining about your rate of download.

Answer 4

Try Spybot Searchand Destroy

Answer 5

Download a trial of:

Windows Live OneCare
Norton Anti-Virus/Internet Security

(They both are trials and will last for about 3 months)

Answer 6

avg pro aint virus, spybot 1.4 and a2squared. are about as good as you'll find.

Answer 7

Scan your computer with everything you have in SAFE MODE.

Answer 8

try norton sercurity
i have it it saved my but once from getting a trojan horse and some kind of pc cleaner (or watever)

Answer 9

get the following, all are free for a safe surfing experience,
install in SAFE mode with networking ( hit F-8 at boot time ), run them all in SAFE mode
with networking as you'll need it for the updates all the programs below will need.
Turn off RESTORE and the RECYLE BIN temporarily as virii can regenerate / reinfect even if you delete
them with both services on. After all the scanning and cleaning after a 2nd reboot and one last
scan do you turn both of them back on.

ANTI VIRAL

AVG (free) http://free.grisoft.com/

and if you have a wireless router follow these tips,


1. Use WPA encryption (WPA-PSK) it's less crackable then WEP.

2. Make a passphrase that is upper & lower case and has some numbers thrown in there as well, again harder to crack.
some like mAkE1t5eCurE0rel53 and as long as possible.

3. Use MAC access control so only you or authorized PC's can connect (even if you do have encryption turned on)

4. Turn off DHCP use static addresses.

5. Turn off SSID (and change it) unless your card really needs it (some do)

6. Change username/password of access unit front end

7. Ensure you have the usual firewall enabled on your PC.

8. Paranoia rules, turn WLAN off if your not using it :)

You've seen the Internet ads: Click here to get your free laptop computer, iPod, trip to Bermuda . . .

Ever wondered what would happen if you tried to claim the freebie?

Generally, you'd end up earning the reward by answering surveys, completing product offers or referring friends.

To find out if the process proved worth the effort, we polled our newsletter readers for a week and asked about their experience with answering ads for free merchandise. Most responded that the freebie turned out to be anything but free.

Here is a sampling of the letters we received.
The free iPod that cost me
"I responded to a free iPod ad. After several requests to sign up for various services, I realized that the free iPod was not free at all. The killing part is, I actually did commit to a few services and have been billed for them, but because I got caught in a loop of pop-up windows and surveys, I became frustrated and did not follow through to get the free iPod.

"I keep saying that I am going contact someone about it, but being the procrastinator that I am, I just haven't gotten around to it yet." -- Rhonda
Free cell phone! What free cell phone?
"Free stuff, what a joke.

"After going through 11 questionnaires and saying no to all, you finally get to the last, and they say you must at least pick two items in order to be able to get whatever they are giving away.

"For instance, I answered a free cell phone ad and went through 11-12 questionnaires and at first it says no obligation to buy anything, but when I got to the last I must at least try magazines for 30 days and they're hoping I will forget to cancel before the 30 days. And the kicker was once I agreed to the free trial of magazines, they never ever mentioned the free cell phone again, and I will be watching and waiting to see what they do to my credit card and if I get the phone, and then that's when I will sue the company for 100 times the amount of the phone and the magazines.

"By the way, once you give one company your credit card number you get charged $1 to $4.95 on your card, for other items I never heard of before and have to take the time to call them and get them to remove it.

Free spam! Act now!
"Yes, they are all scams. There is always a 'short' questionnaire. You always have to answer many, many questions if you want this or that. You always have to give your e-mail address and other information. You always have to check 'yes' for at least one in order to qualify and continue. If you ever get to the end after 45 minutes or so -- yeah, short -- you end up having to buy or sign up for something or your name is put into a lottery for a chance to win. I, in my stupidity, have done this several times. Always thinking maybe this one is legit. Not! I have never gotten the free product or the free gift card, groceries, movie tickets, etc. Then your e-mail is bombarded with hundreds of advertisements that you can never seem to stop unless you change your e-mail address. What a deal. Moral of this story is: Nothing is free." -- Jean

"I filled out the questionnaire online for a $50 gift certificate for dinner at a well-known restaurant chain. They ask for your name and the rest of your personal information and e-mail address. Then the questionnaire opens up a new page and asks you if you would be interested in e-mails for specials on items that you could use in your life. You fill that page out then here comes another page with more questions. After about five pages I gave up. It just wouldn't quit. It was like a stupid carrot that they had hanging out there that you could never reach. I turned my computer off and said, 'Forget that!' After that I didn't check my e-mail for about a week and when I did I had over 200 spam messages, even sex ones. I never did get a dinner certificate. I had to close that e-mail account because the spam garbage would not quit. Moral of the story: There is no free lunch on the Internet." -- Sascha

"I have responded twice to freebie ads, using an alternative e-mail address and within 24 hours received hundreds of spam e-mails -- and no free anything. My perception is the purpose is to get folks to reply and then have access to their e-mail addresses." -- Bea

"After I gave my e-mail address and answered all the questions, I was informed that I had to order (buy) one item from several areas in order to receive the freebie. I canceled the 'adventure' and have been inundated with junk mail ever since. Never again. Big scam for addresses to sell, etc." -- Anita
Complete the never-ending survey
"I tried to win a few of those free products, but I am convinced they are the biggest fraud out there. For example, I spent three hours filling out questionnaires only to find out they never end, and the couple of times I got to the end they wanted me to buy something and you know what that means: They are asking for your credit card information.

"They are scam artists." -- Randy
Free (with shipping and handling)
"I purchased some software from a company that advertises if you pay for shipping you get four software titles for free.

"A few weeks later I got a $49 charge on my account. I looked up the company on the Web and none of the links I found went to the company. I tried the phone number that showed up on my statement and they simply tell you they are not available and to try back later before they hang up on you. So dissatisfied, I searched the Internet a little more only to find I wasn't the only one to be scammed. Turns out that they never tell you that you are signing up for a subscription but send you software and you have a short time frame to return it or be charged. Total scam." -- Kendal
Free (with Social Security and credit card numbers)
"I was scammed. The 'free' gift required my participation in at least six 'promotions,' each of which required signing up for a trial membership and/or paying shipping and handling fees for the information. Plus I was asked to provide credit card and Social Security numbers -- too much sensitive, private and personal information.

"The 'free' gift was never realized, and I felt scammed." -- Edward
Free (with purchase)
"Yes, I've answered ads for 'free' products. Please note the quote marks -- they're intentional. Many of the Internet freebies have extremely long forms to fill out, complete with a host of ads you need to reply 'not interested' to or else you'll receive hundreds of solicitations from various companies.

"The 'gift certificates' offered for sometimes hundreds of dollars almost always involve purchasing something, somewhere along the line or becoming a trial member of something. At which point you need to pay for your subscription or membership upfront, with the caveat it's 'fully refundable' within strict parameters. As the saying goes, there's no such thing as a free lunch!
