Title: "Your computer is infected" warning
Post by: carlrowley1 on February 23, 2010, 11:39:00 PM
Hello guys

I had gone to a web-site, looked harmless enough, and got one of them "your computer is infected" and all sorts of warnings.

I managed to click every X on the screen without any of them coming back, and ran a malwarebytes scan, and picked this up.

But is this related to the "your computer is infected" messages i was getting, or is there something else lurking around..

Or basically is this what malwareBytes had just picked up from the site i had just been to..., the messages have gone know

Hello dragonMaster

Just done a search before i seen your reply

Just checking if necessary to do this, MBAM has changed the value in the registry to (0) so it is not picking this up anymore.
This thread (bottom post)
http://forums.malwarebytes.org/index.php?showtopic=12349

Quote
All this indicates is that the ability to make changes to active desktop is disabled and MBAM is attempting to enable it . If you don't want to see this again tell MBAM to ignore the scan result .


I believe this is from one of the developers of MBAM

But i'll carry on with the combofix scan dragonMaster if its needed, no problem.

Here's another thought , why diden't McAfee site advisor pick this up, all the web-sites listed had green ticks on them.
Anyway its only a 30 day free trial, changed it now to avast

Hello dragonMaster.
I should have mentioned i have windows 7 64 bit

Yes downloaded from the link, but apparantly it says incompatable OS, this only works on XP and 2000.

Also, as soon as i drag CFScript.txt into comboFix.exe the program will run, but  CFScript.txt still shows on the desk top.

Please read the following information that I have provided, which will help you prevent malicious software in the future. Please keep in mind, malware is a continuous danger on the Internet. It is highly important to stay safe while browsing, to prevent re-infection.

Software recommendations

FirewallAntiSpywareNOTE: Please keep ALL of these programs up-to-date and run them whenever you suspect a problem to prevent malware problems.

Resident Protection help
A number of programs have resident protection and it is a good idea to run the resident protection of one of each type of program to maintain protection. However, it is important to run only one resident program of each type since they can conflict and become less effective. That means only one antivirus, firewall, and scanning anti-spyware program at a time. Passive protectors such as SpywareBlaster can be run with any of them.

Rogue programs help
There are a lot of rogue programs out there that want to scare you into giving them your money and some malware actually claims to be security programs. If you get a popup for a security program that you did not install yourself, do NOT click on it and ask for help immediately. It is very important to run an antivirus and firewall, but you can't always rely on reviews and ads for information. Ask in a security forum that you trust if you are not sure. If you are unsure and looking for anti-spyware programs, you can find out if it is a rogue here:
http://www.spywarewarrior.com/rogue_anti-spyware.htm (http://www.spywarewarrior.com/rogue_anti-spyware.htm)

Securing your computerPlease consider using an alternate browser
Mozilla's Firefox browser is a very good alternative. In addition to being generally more secure than Internet Explorer, it has a very good built-in popup blocker and add-ons, like NoScript, can make it even more secure. Opera is another good option.

If you are interested:
See this page (http://www.geekpolice.net/computer-security-f27/preventing-malware-and-being-resistant-to-the-dangers-of-the-internet-t16961.htm) for more info about malware and prevention.

Great and thankyou dragonMaster

hpHosts file replaces your current HOSTS file with one containing well known ad sites and other bad sites. This prevents your computer from connecting to those sites by redirecting them to 127.0.0.1, which is your local computer's loopback address, meaning it will be difficult to infect your computer in the future

I am used to the host file in XP, clicking on " hpHosts file" would this just replace the host file automatically in windows 7 and also in vista

Just one more thing dragonMaster, should i set the DNS client to manual, or keep it started (automatic) just a bit confused over this

Only in extreme situations should you disable this service as caching DNS lookups reduces network traffic and makes internet surfing performance faster

To uninstall ComboFix

Hello DragonMaster

NO windows carn't find " Combofix "  [run]  ( Combofix /Uninstall )

I think when it was installed , and when i tryed to run it and got the pop-up dialog saying " incompatible OS " i deleted the file on the desktop,  which is probably the reason it won't uninstall...

Title: Re: "Your computer is infected" warning
Post by: Dr Jay on March 12, 2010, 07:25:04 AM
OK. No biggie. Just delete the folders from it.

That includes that numbered folder, the file C:\combofix.txt, and C:\Qoobox

Sorry DragonMaster,  How is this updated or can you just leave it like that
Title: Re: "Your computer is infected" warning
Post by: Dr Jay on March 12, 2010, 07:17:20 PM
You can leave it like that.

It updates from time to time, and you can use the same installer over the current install, if you wish to update.

Thats great Dragonmaster.... 8)

Just of the subject a bit, i have just been reading an artical about what the (master boot record) is and does.
What protects the master boot record from becoming infected with a virus ,  would Avast 5.0 stop any virus attacks.

I have paragon backup and recovery, installed on this windows 7 machince, and i have just created a rescue boot disk, but i am still learning how it all works.
But it has an option for correcting the MBR in case you are ever infected with a virus,    but the main thing is how can you protect yourself from a virus getting there in the first place......
Title: Re: "Your computer is infected" warning
Post by: Dr Jay on March 14, 2010, 02:40:01 PM
Most Master Boot Record infections are caused by malware infecting your computer. It is a rootkit, which bypasses system security and infects core system files. Then, with that type of administrative access, it can infect your Master Boot Record.

Stay away from cracks, keygens, music downloads, illegal software, etc.

If you would like to learn about malware, and helping people fight it, I would recommend to see this thread: http://www.computerhope.com/forum/index.php/topic,57605.0.html

Hello there Dragonmaster jay

The ATF cleaner i downloaded, although this is a pritty good tool, i already have ccleaner.
Does ATF cleaner do the same things a ccleaner or does the ATF cleaner have an additional feature, so it might be worth keeping both
Title: Re: "Your computer is infected" warning
Post by: Dr Jay on March 27, 2010, 06:30:02 AM
Occasionally, you can clean a little deeper with ATF, but I use both. Both seem to pick up something, when I run them both at one time.
