Greetings!

Earlier today I did something really stupid, I tried to download a free trial for SonyVegas (the movie editing program) from a site I thought looked OK. Boy was I wrong. After installing it, the first "weird" thing (and the first sign of my computer being infected) I noticed was that Firefox had some kind of default starting page called "Delta Search", there's a toolbar and a searching engine, I haven't used any of them, instead I go via google.

Anyway, I also have this weird Browserprotect.exe file that came as another "happy" surprise with my fake SonyVegas trial.

First, I ran my computer with Superantispyware which detected a Trojan, I sent it to the vault and tried to delete it, but it didn't disappear. Then I did a full scan with Malwarebytes, this program didn't find anything at all.

Then I tried with Hitman PRO, it also found the same Trojan as Superantispyware, and I sent it to the vault, tried to delete it, but nothing happened. It said I had to reboot my computer, which I did. Then I got a blue screen (for unknown reason), so I rebooted my computer again, this time no bluescreen and then some weird "report" appeared for just one second, I didn't have time to photograph but I saw that it said "Hitman Pro and browserprotect.exe" at some places in the text. Anyway, my computer then started as usual, but then when I logged in, all icons where gone and I couldn't do anything. So I rebooted again, this time I came into my computer. First thing I did was to save everything to a USB (virusscanned every file I put on the USB before I exported them), then I started to research the internet for clues. I tried to run awdcleaner a couple of times, but it kept saying "not responding" and I had shut the program down.

Here I sit clueless and very afraid, I don't know much about computers and therefore I had some issues knowing what information you find relevant. Please tell me if you need more info and I'll do my absolute best to provide you with whatever I can!

I'm really grateful about this site and will be very happy for any help!

Hi! I've followed the instructions with TDSSKiller until "Click continue". Now the instructions says that I should reboot my computer. Do you mean that I should press start and reboot manually or should some kind of "Reboot button" have appeared once I pressed "Continue"? Also, the virus has slowed my computer down a lot, so I might need to force shutdown, will that affect my results? Also I don't understand the step "Please post the contents of TDSSKiller.[Version]_[Date]_[Time]_log.txt found in your root directory (typically c:\)in your reply", how do I enter the root directory and get the log?

I'm so sorry for being so bad with computers, I'm so far from a computer genius that you can be. Thanks for helping me, I really, really appreciate it.

Oh and after the scan the threats detected was:

"Hidden file Service: Akamai Suspicious object, medium risk"

"Forged file Service: avgtp Suspicious object, medium risk"

TDSSkiller didnot find anything malicious.Log is not needed.Move to other scans.

Click on startmenu and click on My computer.You will find the C drive.

Thanks alot! Oh and if this helps, this is what the scan from Hitman Pro I did a couple of days ago (before I wrote a post on bleepingcomputer) says, "BrowserProtect-19.0dll TROJAN C:\Documents and settings\All Users\Application Data\Browser Pro" It also says it is quarantined.

Again, thank you so much!

Will Hitman Pro interfere with the Rkill scan by the way? Cause I couldn't find a way to disable it temporary without uninstalling it. (Do you want me to post the Hitman Pro log by the way?)

Hi! I'm running the Malwarebytes scan right now, however I'm a little concerned. I wonder if the trojans I have are likely to spread to other computers through a router or wireless internet (I know some viruses can, is this type of virus likely to?). This computer with the virus is connected to the internet through a wireless connection, could the virus spread from this computer to other computers?

And if it is likely to spread that way, how can I prevent it? Is it enough to turn this computer off when other computers are on? I've had this computer on when other computers have been on, nothing happened to other computers yet, but maybe it takes some time for them to also get infected, is that right?

Again, thank you so much for helping me out!

Hi! I've ran all the scans you wanted me to run now, though I have some questions. The problem is that the language this computer is set to is not English, so some of the logs are in a different language, would it be okay for me to run the logs through a translating program? I wouldn't have any problems with changing the language of the computer though, and run the scans again. What do you prefer?

Anyway, Malwarebytes didn't find any infected files, however AdwCleaner ran for a while and then asked me to reboot, I pressed reboot and when the computer started again both Browserprotect and Deltasearch were gone (is Browserprotect and Deltasearch the trojans ESET Online Scanner found?).

I'll post all the logs as soon as I know how to do with the language issue!

Thank you so, so much, I really can't thank you enough for helping me!

No need to change the language.Just post the logs that you got.

 

You do not have an infection that could spread the network.These are minor adwares and crapwares which doesnt affect your network.
