Hello

 

Two strange things happened recently.  I was posting a comment on a private board and the Time/Date stamp it gave afterwards said my post was two hours different than my own time.  I checked my clock from desktop and it is correct as well as the time zone.  I wanted to run ComboFix to see if anything should come up and a window popped up stating the app did not run on Windows 2000 - but my system is Win 8.1 [see enclosed screenshot].

 

Now I am really concerned there is something wrong here.  Any suggestions?

(I have all updates, windows, flash, java).

Hello shley: 

(snip, snip)...but my system is Win 8.1...

Sorry, but sUBs' ComboFix does not support Windows 8.1.
 
Please read quiteman7's pinned/locked topic http://www.bleepingcomputer.com/forums/t/273628/combofix-usage-questions-help-look-here/ and in particular section :step2: ComboFix System Requirements.

Windows 10, Windows 8.1 and Windows 2000 are NOT supported by ComboFix.

All viruses are malware but not all malware are viruses and if the malware doesn't self replicate it just isn't a virus.

Thank you!

And I suppose the clock issue is a server side issue and not my unit's problem.  I'll just continue to monitor it.

Thanks a bunch.

If you need individual assistance with a malware infection, other advanced tools are available but they cannot be used in this forum. You would need to follow the instructions in the Preparation Guide For Requesting Help starting at Step 6.
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.
When you have done that post your logs in the in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here for assistance by the Malware Response Team Experts.

Start a new topic, give it a relevant title along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

If you choose to follow the above instructions and post a FRST log, please reply back in this thread with a link to the new topic so we can closed this one. If not, at least you know doing that is an option available to you.

It appears the FRST file is not acceptable per my a/v.  It was flagged as a uncommon download file which is highly unusual... so I can't run it in this system without taking a risk.

Bleeping Computer's hosted programs for download are trustworthy, safe and malware-free. However depending on the product some anti-virus software and other security scanners may flag certain programs as a threat for a variety of reasons when that is not the case.

Certain embedded files that are part of legitimate programs and specialized fix tools (like <insert name>), may at times be detected by some anti-virus and anti-malware scanners as suspicious, a Risk Tool, Hacking Tool, Potentially Unwanted Program, a possible threat or even Malware (virus/trojan) when that is not the case. This occurs for a variety of reasons to include the tool's compiler, the files it uses, whether files are compressed or packed, what behavior (routines, scripts, etc) it performs, any registry strings it may contain and the type of security engine that was used during the scan. Other legitimate files which may be obfuscated, encrypted or password protected in order to conceal itself so they do not allow access for scanning but often trigger alerts by anti-virus software.

When flagged by an anti-virus or security scanner, it's because the program includes features, behavior or files that appear suspicious or which can potentially be used for malicious purposes. Compressed and packed files in particular are often flagged as suspicious by security software because they have difficulty reading what is inside them. These detections do not necessarily mean the file is malicious or a bad program. It means it has the potential for being misused by others or that it was simply detected as suspicious or a threat due to the security program's heuristic analysis engine which provides the ability to detect possible new variants of malware. Anti-virus scanners cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert you or even automatically remove them. In these cases the detection is a "false positive" and can be ignored.

Most of the well known specialized tools we use against malware are written by experts/Security Colleagues at various security forums like Bleeping Computer, TechSupport, GeeksToGo, SypwareInfo and other similar sites so they can be trusted...this includes any program hosted by BC for download. Unfortunately, many of these tools are repeatedly falsely detected by various anti-virus programs from time to time for the reasons noted above.

The problem is really with the anti-virus vendors who keep targeting these embedded files and NOT with the tools themselves. We can inform the developers but they have encountered this issue many times before and in most cases there isn't much they can do about it. Once the detection is reported to the anti-virus vendor, they are usually quick to fix it by releasing an updated definition database.

Either have your anti-virus ignore the detection or temporarily disable it until you download and run the tool. Another option is to download from another computer with a different antivirus, save to a USB drive and transfer it to the computer you need to run the tool. If you do that, you still may need to temporarily disable your antivirus.

I posted what you said but no one has answered the logs I posted.

"Slow browser, video skips, and other strange behaviors" is the title.

I probably should have mentioned more of the behaviors.  Internet page freezes so I can't scroll down anymore; Windows Security Service Center stops working intermittently.  Just strange behaviors.

Your new topic is posted here.

Now that your new topic is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Response Team member...nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the information or any log(s) you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process or make things worst which would extend the time it takes to clean your computer.

From this point on the Malware Response Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take several days to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers but your topic will be reviewed and answered as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.

I advise checking your new topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, please follow Step One and CLICK the link so it will report your topic to the team members.
