Virus attack

[BnB]

Yesterday I downloaded an exe file then I run it and nothing happened.

When I started my computer (winlogon.exe) a message appeared which

was saying the sshnas21.dll was missing, I think windows fire wall deleted

the file.

 

p.s. I don't have any anti-virus

 

Please help me!

Thanks.

Why would you not have an antivirus? That's akin to going swimming in the middle of the Atlantic without a flotation device, while bleeding profusely from your leg in the middle of a swarm of sharks.

 

Get Avira/Avast for f*cks sake.

[james227uk]

A firewall wouldn't have protected you in the first place, you should have an AV. It's critical, it's one of the first things you should consider putting on a PC, even before you start to access the net.

 

Can you boot into Safe Mode? If you can, boot into Safe Mode with Networking, then download and install an anti virus + Malwarebytes anti malware

 

 

EDIT:

 

I searched for "sshnas21.dll" on my C drive and couldn't find it, unless it's not a file included in Windows 7, it's a rogue.

 

[AmyJones]

Run spybot S&D in safe mode before doing anything. sshnas21.dll is a trojan file.

It's a virus that's connected to fake adobe flash player updates. It's pretty nasty, it also prompts you to download more files that further screw your computer up with fake windows alerts.

Wow, no AV, just wow.

 

At any rate, once a computer is compromised with a virus I would not ever trust it, especially if it had no AV at all, I would only trust it after a completely new clean install of Windows.

 

EDIT: Oh and after you do that, install an AV program.

Too be honest i run without an Anti-virus. I have for years. It's all about knowing what you're doing and what you are downloading to your computer. For most people like me it's having a program like syybot in case you make a mistake and not paying a company like norton to wipe your ass for a fee.

[SyphonPayne]

I would prefer not to try and outsmart the virus programmers. You may think your system is clean but when you get a virus especially without an AV you have no idea what it can/will be doing. When you have no AV, you can get a virus without even realizing it. I would NEVER EVER do anything with sensitive data such as online banking (which I do every day) on a computer with no AV. If the computer has had a virus in the past even with an AV again I will NOT trust it until it has been wiped clean and Windows reinstalled.

 

Spybot is a good program, but it is meant to supplement, not replace a good AV program. Spybot alone will not catch everything, and it has been criticized in the past for not catching everything. Some people consider it a rather "old" program for catching modern-day viruses. Again, it's a great tool, when used along with other anti-malware and antivirus programs.

 

Granted, if you only go to sites you trust, and don't deal with sensitive data, it might work out without an AV, but I'd just rather be safe than sorry. Online identity theft is a growing trend that's not going to die down anytime soon.

[SWEETSAPRIK]

It's actually possible to run a PC with no AV and be completely safe, but the hoops you have to jump though to be safe make browsing almost impossible. You'd have to never load scripts which breaks most pages, have your firewall set to block everything that you don't specifically allow which triples the time it takes to load anything as you have to allow things one at a time, and for that matter, not click on every damn thing. Basically you'd need to be a paranoid security expert and not browse like a normal user. Downloading random exe files pretty much rules out you being capable of this. Under almost any circumstances other that being a paranoid security expert, not running an AV is stupid.

 

Also, a firewall won't delete anything. Unless you have one of those stupid "suite" programs with something in it other than a firewall, and even then the only (non-malicious) program that should ever delete a file would be an AV, and only after warning you about it and asking you if you're sure you want to delete it, in case it is a false positive.

 

If I were you I'd run Spybot S&D, HijackThis, and then Avira AntiVir, they're all free btw. With the first two I'd make sure not to delete anything you actually need. With the later I'd run a complete scan and then leave the active "guard" bit running.

 

Now while I have had an infection or two on my older PC over the years, I've never had to reformat or reinstall Windows, I always just fixed the problem. That said, with things like rootkits out there now SyphonPayne is unfortunately correct. If you have something like a rootkit on your PC your AV cannot possibly find it, because it uses the OS, which may have been compromised. So even though you might be able to completely remove the malicious bits causing the problem, you can never be 100% certain that everything is gone.

 

If not AntiVir, at least get one of the many free AV programs with an active scanning component, so in the future it might catch these things before they can bite you. Most importantly, DON'T DOWNLOAD AND RUN DODGY EXE FILES. If you keep doing that, even the best firewall and antivirus can't stop you from infecting yourself.

There's absolutely no excuse not to have an AV these days. Since the best ones are completely free and readily available.

[SyphonPayne]

Hah. Just realized the comment about Norton.

 

 

Yeah Norton is a piece of crap. No doubt. Don't EVER pay for that crap, or McAfee.

 

As has been previously stated, there are plenty of good free AV's out there.

[BnB]

@Sweets Thanks a lot thoose AV are great.

Thank you all problem solved.

I didn't have AV because my PC is brand-new.

[james227uk]

Brand new PC's already come included with an AV, usually Norton. Unless it was a home built PC of course

norton ain't that bad. the only thing bout norton is that it blocks almost every program/file that they think is bad. usually they block programs when a person have reported the site that you downloaded from or ur the first person to download that file. you can edit the norton settings though on what to allow and what not to allow. i love norton as it can disarm a trojon horse within a second. as my com have been recieving trojon horse recently, i like norton. also norton can scan mobile games for virus, usually most virus tools cannot scan mobile games but because i download apps and games from un trusted site to my mobile everytime and i just cannot bare to lose my android phone. the last time i used AVG and downloaded a mobile game, that mobile game crashed my phone mother board and i asked experts from mobile forums and they said that my phone is as good as a brick, after that i used norton 360, whenever i download a app that has virus my norton will usually warn me or even delete it for me. i have 100 of games in my phone and none of them are corrupted. kaspersky is also a good virus program but not as well known as norton but i think its the same as norton but i just install it for double safety . and free anti virus programs arnt very good as i ever tried 1 free anti virus program but i figured out that the program cannot block trojon horse. so much for "the number 1 best anti virus software in the world" -.-

[james227uk]

Fail. There's free AVs out there (Avira, Avast etc) that make Norton look like total sh*t. Norton clogged up my PC, degraded it's performace whilst it was running since it uses too many resources, and let viruses through. It gave me sh*t tons of false positives, and deleted stuff that wasn't even a virus. According to statistics, it's the most popular AV. Because of that, there's way more people probing Norton for exploits.

 

There is no point in paying for an AV when the free ones are just as good, if not better. And I assure you, if you uninstall Norton of your PC you will see a performace boost.

 

And I know for a fact that Avast will scan anything i throw at it. I made a file with the extention "ddkhkf" and Avast still offered to scan it.

 

Norton is too bloated and does more harm than good. Next time I buy a PC, I'm not even using the free trial of Norton. It's going straight away

 

 

Just google "Norton is crap" is google, and you'll find some good articles to read.

 

Don't forget that cost does not equal quality. Just because it's a payed for AV doesn't make it better

[Cojage]

Malwarebytes or Superantispyware always seem to catch adware/viruses for me that NOD32 doesn't detect. Also install Microsoft Security essentials, it's free and pretty good.

[james227uk]

So you're suggesting to use two antiviruses at the same time? Unless I misunderstand the Microsoft one, that means he'd be running two at the same time, and that isn't a good idea

[SWEETSAPRIK]

Neither of the first two are antivirus programs, and I could be mistaken, but I don't he said he was running both MSE and NOD32.

 

Some people don't seem to make a proper distinction between adware, spyware, and viruses. While I don't care for NOD32 or MSE, the reason a program like malwarebytes picks up things they don't isn't because it is better, it is because they're looking for different things. Though I think MSE might actually contain Windows Defender's spyware definitions now.

 

For example, before Adaware changed to the point where I stopped using it, it was one of the only scanners that found tracking cookies. Not because it was better, but because tracking cookies are not viruses (and as unwanted as they might be to some from a privacy standpoint, they aren't technically spyware, adware, or even malware), so it found them when others didn't simply because nothing else even bothered looking for them.

 

Running something for viruses and something else for spyware, etc., shouldn't cause a problem, at least it has never caused me one, and I can't remember hearing about anyone else having conflicts. With multiple AVs you could run into problems like slowdowns, conflicts and crashes, but that's usually just with the active scanning portion of the programs. That can be solved by never running more than one AV's active scanner at a time. Beyond that your biggest concern would be one program picking up components of the other (such as virus definitions) and considering them malicious.

 

It is possible to run more than one AV at a time (NOD32 and MSE for example) and not run into problems, but I wouldn't advise it. And even if you can get it to work without running into any problems, it wouldn't necessarily make you any safer anyway.

i run norton and kaspersky at the same time xd

[oldage]

i run norton and kaspersky at the same time xd

hmmm...now why would you want to use norton? (I tried it after hearing all the hate on it and boy I agree with it being crap)

[james227uk]

@Sweets

 

I was talking about where he said to install nod32, then install Microsoft Security Essentials too.

[The-King]

hmmm...now why would you want to use norton? (I tried it after hearing all the hate on it and boy I agree with it being crap)

I used it once, tried to uninstall it and realized that it's virtually impossible to remove from a computer without a whole sh*tload of loopholes and fancy registry editing. Then I used it again when I forgot to deselect it when installing a bunch of drivers for my laptop, had to end it's processes manually whenever I needed to boot my computer.

 

Thank god that HD died, I got 7 and my driver CD wasn't compatible, so I didn't risk getting Norton embedded in my system again.

 

It might as well be a virus itself since it's designed to dig itself into your computer as deep as it can go.

[Cojage]

 

@Sweets

No I said I was running NOD, not that he should install NOD. I recommended MSE because it's free, maybe even the best free AV out there now.

 

And indeed as Sweets said, the first aren't AV programs but are focused on malware/adware, which are diffirent from trojans, although they usually catch trojans too

[james227uk]

Yes, I am quite aware of what they do. I used these prograns for years, I don't need an explanation

dude you can just go to start> all applications>norton> uninstall norton. if urs don't have that u probrably got the demo version of it or ur norton is not 2010. if u cannot remove from there go to control panels and remove programs and click norton and click remove. srsly is it that hard ?

[kudoboi]

using those 2 ways u can uninstall any program as long as it is found in documents or my computer. if its place as desktop delete it manually.

[james227uk]

Use the Edit button don't double post

 

And King is right. I had trouble removing the norton trial on my laptop when I first got it. It does burrow itself into your PC

 

And please stop defending Norton, you can't change our minds about it being total crap. You honestly believe it's as easy as that to remove? Sysmantec had to release a dedicated tool to completely remove it.

Hi friends, is AVAST a good antivirus? I had Norton (but I didn't like it very much), AVG (I didn't like it very much, it has too many false positives), and I had Antivir, but it made my computer became slower. So Avast was the best for me. I don't want to pay for an anti-virus, since I don't have too many virus issues. And what about register cleaners, like CCleaner? Is it dangerous to use them?

@Cidamelo

 

If it works for you, then fine. Yes, Avast is one of the best out there.

 

And no, registry cleaners are not 100% safe. It they were, why do you think they offer to make a regustry backup?
