Is your bios battery old?
Do a scan also with several of the programs included here
Do stinger ( It needs to be downloaded daily to get the latest version
Getsusp looks for unknown files and will send them to Mcafee . Ensure you add your email it the preferences so they can update you
Malwarebytes Download the free 1 and do not accept trial option.
All said there is 1 other post re possible bios issues
Cannot be Mcafee causing it and rare that malware can affect bios.
Check above and update us please
Thank you for quick respons!
I bought the PC new in december 2009 so it can't be old (?) I didn't mean McAfee caused the problem, it just doesn't seem to find it
At this point the PC works ok if you can block out the vetilator going full speed (almost like it's trying to fly)
I will try your links! But i am at work today and try first tomorrow.
I will come with an update tomorrow!
3 years is possible bad bios battery. I have seen them go between then and 5 years so a possibility.
see what you get when you try the above
After only 3 years???
I bought my first PC 2003 and that one is still going strong!
It just didn't have the GB's and RAM we needed...
Well I am defenitly no PC expert
What can i do with a bad BIOS Battery?
It depends on what machine and model you have and what motherboard it has how you go about it, but usually it's as simple as noting the what type of battery it has, going to the nearest PC Shop, drugstore or a hardware shop and buying a replacement. They're usually the large button variety. A CR2302 or DL2302 depending on brand is what all my machines have used. Replacing a battery will most likely regress the BIOS to it's original state so be prepared tp update the BIOS afterwards and to make any adjustments that you may have made all over again.
It could also be simply a loose battery or loose connection to the motherboard, but a PC repair shop is best to check that.
Agreed it's unusual for a battery to go so soon but it's also extremely unusual for a BIOS infection to occur as an up-to-date Windows would have caught it long ago with the monthly Malicious Software Removal tool that downloads and scans every month.
If you post more information about your machine perhaps we can locate a guide for you, although a Google Search would probably find it for you.
If in the unusual instance that it is an infection. Trojan.mebromi can infect the BIOS, but a fully patched machine should not allow it in, in the first place.
At McAfee it's known by another name, see the Removal Tab here: http://home.mcafee.com/virusinfo/virusprofile.aspx?key=584636#none
As a precaution try Stinger and Malwarebytes Free (don't accept the trial) both linked in my signature.
If you are unsure of your motherboard's name download Belarc Advisor and let it run. It will produce a report listing everything about your machine, including 'Main Curcuit Board'.
Moved to Malware Discussions > Home User Assistance, just in case.
I have an ACER Aspire M3802 (not sure about the number) dual core. It's a desktop. It has Windows 7 Home Edition on it.
Nearest PC shop is about 100 km away but i can ring them and hear with them. To send the PC to an expert is no option: it's cheaper to buy my self a new one...
Where can i find this battery in the PC?
Is it normal that the ventilator is trying to 'take off' when the battery is bad?
Motherboard: i have no idea what that may be (i know, i am absolutely blank about PC-technics!)
What does it mean for me when the BIOS goes in it's original state? Is all my work gone then?
I will try out every option you all gave me!
Coming with a update tomorrow!
Not it's not normal for the fan to roar, which is what I assume you meant by ventilator taking off. That usually indicates that some process is using up all the resources.
Try running Stinger & Malwarebytes Free especially in this case. Note that Malwarebytes can also be run in Safe Mode if necessary.
Sorry, I didn't realise that you were reading the post as I made changes, you may need to redisplay the page as I altered my original response a few times.
Replacing a BIOS battery reverts the BIOS settings to their factory state so then you go to ACER's website and update it, see the BIOS tab here: http://support.acer.com/product/default.aspx?modelId=1776 (You may need to change Country depending where you are - see that link at the bottom right). Also see the other tabs for documentation etc.
By the way it could be also a good time to clean out the dust from inside your computer case and around the fan(s). You have to be careful not to damage anything or short-circuit electrical components but a Google Search on this subject should help you.
That could also be the cause of fans going crazy.
