AVG found trojan horse

It called "Trojan Horse Downloader Agent2 APF". Path to file:

ProgramsFiles>Real>RealPlayer\Setup\au_setup6.exe

Of course I sent it to the Virus Vault. And I wondered why Real Player was just launching itself randomly.

My question is I cannot find the setup6.exe file. I guess it went to the vault? I am wondering if I should uninstall and re-install RealPlayer again?

What's the best rule of thumb to download with safety? I've heard of "mirror" sites?

Should I uninstall Realplayer? I've got a lot of playlists in there. Just wondering if this is going to be a problem. Thanks!

dk,

Thanks! I'm not sure if I downloaded from the "Real" site. But now I know better, and I bookmarked the link you gave me. I'm kind of stumped if I should uninstall my current RealPlayer program. When I went to the control panel to uninstall, it does show Real Networks as the publisher, so I'm not sure if that means I went to the Real site to download. Sometimes I go to free downloads.com or cnet, etc. I guess if I see RealPlayer acting up again, or if I get another message from AVG, it's time to uninstall, huh?

Unfortunately there have been quite a few false positives from AVG lately. Because of this quite a few of us have changed to AVAST free.

They all do. Unless too many like in being annoying I dont see much trouble with FPs. Program is set up to deal with false positives and user, or whoever is admin, should know. Part of AV. If whatever product, or review, claim there are no FPs they are lying or worse have made AV foolproof by chosing safe path = low detection rate. Why Microsoft never have had many FPs - good but also bad.

AV-Comparatives have also jumped the wagon. To some extend they award AVs according to number of FPs. That is nuts, also meaningless because it only take 1 FP to confuse users if they are to be stroked 100%.

Stories about system files being quarantined are unfortunate of course, Eset False Positive Fiasco - DonationCoder.com Think he is pissed off because many of the tools he care about have been flagged, like autohotkey stuff :) They dont take notice because only few complain. Should be kept to the fire but is wrong to make FP a major issue.

My Avira thing sucks with excluding programs. How program communicates with user regarding FPs, is much more important than if it happens to suspect Real Player for a day or 2 - or have X more than another AV with lower detection rate. Besides, flagging Real Player just shows AVG have some taste ;)

I like Avast, you can report FPs directly from Webshields "A Virus was found" window ("There is no reason to worry, though.") Disable that and you get same msg from standard shield, except now "There is no reason to panic, though". They have put some thought in to this problem.

I'm getting a little more concerned now. I sent a picture to a friend and she said that her AV found a virus attached to my pic. I've been pop-ups like crazy using Firefox (just looked though and popups were not blocked). Firefox has been acting crazy like now downloading full files. I'm not sure if I should do a restore with Vista, just back a couple of weeks.

I see there is a free PC scan link that was after your post. Is that link safe?

I'm wondering if I should uninstall and reinstall Firefox. Guess I can save my bookmarks. Geez, what a hassle.

I will try to decipher what you had written to me. Lots there. Thanks.

Well scan away with a new beta of ESETs online scanner then ESET Online Scanner Beta Program but I would not let it remove anything. Why is partly because of FP - just not safe to trust so much, even less an online scanner. Though this one seem to have implemented quarantine. Wise works from FAQ:

Why are infected files in quarantine after the scan?
All infiltrations and infected files are moved into the quarantine by default. Files in quarantine no longer represent a threat for your computer, because they are reliably isolated from all parts of the operating system. The user can choose either to restore selected files or delete the quarantine.
Warning!
Please, restore files from quarantine only if you are sure that it is not malware or an infected file.


I will only suggest you let it report. Deal with infections afterwards. Old one was horrible because it would not let you save results, now you can - export to text-file and post it here.

Should be close to 100% safe to install and run Malwarebytes Malwarebytes.org does also not find anything but is good at removal, not the same as detection but just as important.

System Restore could work as wel, if there is anything to fix, but would be a good idea if you found out what problem is, what went wrong - what you will not do again, have to protect better against.

Well, I don't use IE, I use Firefox which could be one of my problems. But I did do the free scan. I do not know how to do a screen shot to show you. Please teach me how to do a screen shot and put this up on this site.

Three threats, mostly cookies. I did not remove them, as you suggested.

I my browser, should I accept all cookies?

Let me know how I should take the next procedure. TXS.

I'm gonna try this screen shot. It's the result of the free scan you suggested.

I get these cookie warnings ALL the time using AVG. Maybe I should raise my level of protection in my browser? How much of a threat are these? What should my setting be in my browser? Should I remove these threats now? you said wait and show you first.

Good example of why so many security programs suck. Forget about those cookies, they are harmless. Damn ESET, let Spybot freak people out. According to ESET you are clean.

Anyway I think you did not untick remove "unwanted" progams or something. Why it includes tiny cookies. Is a risky setting because many normal programs can be considered "unwanted", may be you dont even mind some adware. If just following program it will be removed... False Positives the same.

Type Snip in start menu, there should be a build in screen capture in Vista.

Yes you will get those cookies all the time - because they are all over the internet. Waste of your time to "handle" cookies to avoid but you could use Adblock Plus and subscribe to Easylist. Will remove most ads and fewer cookies will be on hd. There is also an addition to Easylist, called Easylist Privacy which block those sweet "tracking" cookies http://easylist.adblockplus.org/ - if you do that remember to whitelist/disable Adblock on sites you like.

How to install Adblock http://adblockplus.org/en/

If you cant live with Cookies but not prepared to block all then go to add-on site - there are some extensions which can deal with them. Like Adblock does ads. Get one of the more popular ones. A simple search for cookies like this https://addons.mozilla.org/en-US/firefox/search?q=cookies&cat=all will give plenty of choices. There is a technical side to cookies, from web developer point of view - you spending time allowing/blocking cookies is definition of being bored.

For better protection against real dangers install WOT http://www.mywot.com/ May be also go through AVG settings, dont know if it is free or paid you have. You are not on top of things if scared by a text-file/cookie ;)

Keep Malwarebytes installed if you tried it. Is deadeasy to use, click update - then quickscan from time to time. You will find it hard to install stuff from crappy sites with WOT though. Check videos on their site for how it works, they just improved interface a lot. You decide what to block and what to warn against. Will not be problem to surf with.

I did use Snip to give you the screen shot. It's kind of small to look at it, but I guess you can see it. No, I did not untick the threats. I will just leave them if you think that's the best thing to do. Think I should go with Avast instead of AVG? I don't know why I sent a pic to a friend and she said her system showed a virus attached to my pic. Whatever. I'm getting more confused each day. I just want to make my computer simple for my life, not more time and energy and stress. I"m sorry, just venting!

Im trying to make it simple and not suggest complicated solutions to problem that does not exist :) You need one of those "how-to-stay-safe" guides I think. There are many of those but they often go crazy and want you to install stuff of no value. Use what has proven to work and focus on understanding more than getting upset. Computer has been declared clean by ESET and AVG so that will do.

Your friend is probably confused. May be AVG attach a note saying "Scanned by AVG xxxx" to any email you send out? Settngs, settings and settings :) You should know AV program.

If you paid for AVG then keep it, if not Avast is good alternative - I think better but you find out. They are about equal in detection rates and have been so for years, Avast has many more features in free/home version though. Hardly limited compared to paid. Well use Avast if tired of AVG.

Now you also know how to make an extra check, use ESET or other online scanner. Theirs is still beta but seems to be good. Some like me will prefer to let online scanner report only and this is now possible. No need for screenshots even, can export result to text-file.

Does not matter what you do about cookies, not a threat to you or computer. Bad security programs often try to scare people by listing ton of "found threats" like these. BS. Programs know that 99 out of 100 computers will have those threats.

dk,

ok, thanks for helping me to calm down. I bought this computer about 1 month ago and had this vision of doing a complete restore, etc., etc. and losing apps that people gave me etc. I wish I was more techie than I am. but for the most part, I'm just gonna concentate on a couple of things. Downloading from the authentic sites. And switching to Avast instead of AVG (I have the free version). And if I get a threat, I'll just come here and ask you guys if it's real. I don't know about putting stuff into quaritnine. Most people don't. Yeah, I know about other people's systems like if they are using Yahoo or other web-based email programs, they have their automtaic AV programs to scan attachments, whatever. I'm just gonna take a few deep breaths and say I can't learn everything there is so learn tonight so I'm gonna let this go and know that my computer is clean and I will re-read everything you wrote and go from there. I'm sort of an anxious kind of gal, so I'm just gonna take a break from it all. So far, I'm not getting any error messages today, outside those cookie threats. Geez, even I know that some cookies are necessary to visit websites.

Anyway, thanks for helping me with this. I appreciate your efforts and information. I really do :)

Only one way learn about this, wont help to read guides - confusing and may be risky if you just follow each and every suggestion. Security should be simple and easy.

Well if you chose Avast be sure to uninstall AVG first, there should only be 1 AV installed a time.

Avast require you to register but nothing personal as such. They will send you email with serial-code and this must be repeated about once per year. Thats it. Many use Avast so easy to get help. Their own user-forum is pretty good. Default install and settings should work fine.

For this "internet" threat best you can do is using WOT. If you click on a bad url in an email or where ever it is likely to block/warn you of site. There is nothing more to it. No effort required on your side. WOT try to do much more, also encourage users to evaluate sites - if you have had bad experience buying stuff from a shop you can warn others through WOT and score card page. Each site has its own page where people can write down comments. You dont have to, tool is effective in blocking based on sources collecting bad sites. Is free. You can almost turn brain off while surfing with WOT ;) Set it up as you please, check settings etc.

WOT have videos on site explaining, here is another less annnoying... Dont rush to install but research what WOT is. Is very much a hold your hand layer of protection, just go with defaults but important you know how it works. Why a "yellow" could be False Postive for example. Ive set mine up so only RED is relevant. And only in IE8 because otherwize I cant go to sites with malware, heh. Firefox attack/phising filter also quite effective btw. IE8s also. WOT site is pretty good with forums etc. so dig in.
