I have had it happen a few times that the PC clock has been re-set for whatever reason (possibly with a BSOD issue but most likely caused by Malware infection) to the year 2099! :o

Usually it gets set to the 1/1/2099 with or without a different or wrong day of the Week, and while it isn't too much of a bother returning the date & time back in Windows 7 this is quite annoying to have to do but...

The bigger concern, especially if it is a form of hack vulnerability for a sleeping backdoor trojan or malware exploit that is activated when the system clock is adjusted to that ridiculously future arbitrary date a few things stop working properly especially security software with end date licenses, so they just automatically stop functioning.

Avast! is one such program that unfortunately stops functioning completely and fails like others to be allowed to update or re-start in 2099, IME. I've had this happen a few times in the past and figure that a full system reformat swipe and re-install ultimately is the most secure way to completely clean the PC in such cases where even after returning to current date & time scans can't find the fault or cause. (Which I had to do recently.)

While it may not be absolutely necessary to go through this extreme procedure, I find it loathsome that while the PC was unfathomably re-set to the year 2099 my Avast! resident AV had turned itself off no matter what the reason was for the PC year date change.

Because it is more than likely to have been a suspicious action and most likely to have allowed for further unchecked activities with Avast! and other security turned off, I think it would be good to have Avast! still fully function if the year is 'discovered' to be 2099. ;)

Sure this won't prevent similar issues with inexplicable randomly year changes, but for some reason this year 2099 thing is pretty regular and might be a MS Windows default thing anyway, so it would help in these most frequent circumstances of this type of occurrence if Avast! could be somehow set to still fully function if the year 2099 is encountered.

Hi Saulius,

     You certainly have a problem I've never encountered!  Perhaps someone more knowledgeable than I can explain what is happening here.

Normally I would suspect the CMOS battery - but that usually reverts to the installation date and time...  So 'tis a bit weird

@spc3rd

Yes, nothing found even after the likes of SAS and MBAM have been updated and I've even tried more extreme methods with Combo fix etc.

This has happened more than once and I have gone through the process of deleting my system including storage drives for good measure and re-formating and cleaning re-installing W7.

I take it as a sign of a massive system compromise which I heavily suspect it actually is of its self with the re-setting to 2099 and outside of licence end date by too far...

I don't know too much about this really, but because it manages to turn off most security features and programs I assume it's bad even if it is caused by a conflict or through MS ineptitude, although I think it usually occurs with BSOD and a series of failed boot ups with my Asus Mobo which might require the BIOS to be explored.  ???

@essexboy

I sometimes have to hit the CMOS re-set button or choose to restore default BIOS settings before actually getting to even boot up into the Asus Mobo BIOS setting and neither of these actions result in a re-setting to the year 2099. In fact IIRC it is only the OS date that is 2099, not the CMOS battery which will still be at current!

That combination sounds like a MOBO problem to me

This is a very interesting theory that should be taken into account.

A very dangerous exploit if used properly. >:(

Sorry Essexboy, I should have also indicated that I remember a few of the BSODs being preceded by a few likely infections, such as odd online behaviour hold ups, 4/504s & redirects,  possible bot worm events etc, you know the kinds of things that you just know involved your PC getting infected with something despite all your security, precautions and conscientious browsing.  :-[

@!Donovan Um, "A very dangerous exploit if used properly" by whom? (And those parties are the questionable ppls.)

Exactly, so if I know not what but am sure 'tis some weird horror then the only guaranteed removal for clean system integrity is a complete re-formated install since who knows just what the whatever kind of undetectable recalcitrant probable infection is doing with my system, possibly not even their makers!  :'(

There is only one at the moment that will survive a re-install

Download aswMBR.exe ( 4.1mb ) to your desktop.
 Double click the aswMBR.exe to run it  Click the "Scan" button to start scan 



On completion of the scan click save log, save it to your desktop and post in your next reply

I'm not saying that I still have the infection, I'm pointing out my experience with a particular suspect issue of my system clock date being re-set to 2099 which has occurred a few times for me and what it results in with regard to the dysfunctionality of Avast! as resident AV (not only own its own in that boat in the situation) and that it could be something that could possibly be addressed.

I am interested to know if anyone else has experienced this 2099 re-setting of the year thing, which I'm positive is only the OS, but it could be the CMOS/BOIs too, but I'm pretty sure it's just the former.

I have used aswMBR quite regularly over many months and in relation to such instances a few times when my system clock has been re-set to the year 2099 and also once I have re-installed it on my clean system after a complete re-formating procedure, anyway I've conducted another scan with it but I think it is clear:

Name, please?

Reason is so one does not waste time trying to clean, but uses another hdd to install.

Nope there is no sign of the TDL stealth there so I would assess it to be a hardware problem of some sort

clocks being reset on the system (OS) to one or two years earlier have one single reason generally, running an illegal version of Windows. Some "patches" just do that. I've seen it on someone's XP computer, that prevented the system from checking for updates, from checking if Windows was activated, and detect that Windows was not genuine  ;D

ps: BSOD's don't do that  :D

Using some (small size) Live CD/UFD to check the date/time is an alternative.

In theory, the CMOS, Windows OS and Live CD date/time should be all the same (except, maybe, for some Daylight Saving Time difference).

According to what the Live CD would show, and correcting the CMOS clock, you should be able to identify if the problem is either hardware, the CMOS battery, power failure or some software-related issue.
