Erratic computer which has now lost wifi connection.

Hello, For a while my laptop has been quite erratic.
Whilst I was writing a text document in open office it came up with a warning saying that a trojan was trying to download but it seemed to be my Avast saying that it was infact the virus? Everything started flashing (desktop, text document etc) then the screen went blue (no writing). I had to use 'control alt delete' to be able to close down but it was 'closing down' for about 15 mins so I had to close with the button. I got a lot of warnings (one after the other) about a trojan trying to install itself. When I shut down, the blue screen with the whirling donut takes forever. After about 15 mins I usually just have to press the power button to turn off.
I can continue working on-line even when the desktop has disappeared. As soon as I go to the desktop I lose everything. and have to hard restart. I get the warning messages constantly.
Then I lost the [FONT=inherit !important][FONT=inherit !important]wifi
[FONT=inherit !important]connection[/FONT][/FONT]. I am at home using my own router and all my other devices are working fine. It is picking it up, showing 5 bars and saying it is connected and I have internet access, but will not go onto any Internet. Chrome says DNS PROBE FINISHED NO INTERNET.
When I ran troubleshooting on the wifi connection the the problem found was ' the remote device or resource won't accept the connection'. I have tried to create a new wifi connection with my router but didn't manage to do that.
I tried to do a system restore but it failed. I also tried to restore to factory settings but after 'preparing' it said 'insert media.... Some files are missing.......your windows installation or recovery media will provide these files'.
I am running now with the wired LAN connection.
Is there anything you can advise please?
If I go ahead and upgrade to W10 will everything reset again?
Thanks in advance, Jan

You'd be best to make a Recovery CD/Usb from another computer and start up your computer with that USB/CD and start saving your documents to an external drive/usb/cd..

How to create USB rescue media

But if you want to take a chance, You can try to clean the virus out using Eset and Bleeping Computers programs..

Start with Eset Online Scanner and run it through your web browser.. Are you using Firefox by any chance? or Chrome? you can do things like "Refresh Firefox" to force out any bad things in your browser before you connect online to use these tools..


when running the scan select These options.." posted below

Free Virus Scan | ESET Online Scanner | ESET

Then head over to Bleeping computer and get these:


BleepingComputer.com - News, Reviews, and Technical Support

Hitman Pro
MalewareBytes
NetAdapterRepair
Rkill.exe
RogueKiller
TdssKiller
TFC.exe
Autoruns
Adwcleaner




It's time for a Complete Format and Reinstall in my opinion.. but you'll need to copy all your documents via that usb recovery method I mentioned in the beginning..

erratic laptop

Hello
brooksndun, thanks for the reply. I thought it was a virus at first, but I've used MajorGeeks malware forum and run loads of scans which they have analysed and they say I am not infected. The erratic [FONT=Segoe UI, verdana, Tahoma, Calibri, Verdana, Geneva, sans-serif]behaviour[/FONT] has actually stopped for about 5-6 days now. The main problem I am having is being unable to use the wifi. I can connect with the cable. The laptop picks up the wifi, shows 5 bars and says it is connected but I cannot actually go on the internet. In Chrome I get a message saying either
DNS PROBE FINISHED NO INTERNET or "The remote device or resource won't accept the connection".


I attempted a system restore but it wouldn't. Even tried back to factory settings, but after 'preparing' it said 'insert media.... Some files are missing.......your windows installation or recovery media will provide these files'.

Yesterday I downloaded W10 to have it ready in case I decided to go ahead and upgrade. I thought I had chosen the option to download but install at a later date but it just carried on and installed. So, I now have W10 and still have exactly the same problem with wifi.

Any advice you have would be much appreciated.

Thanks again.
I will work through these links.
As I can link to my router no problem with the LAN cable (or is it called Ethernet?) just not with the wifi, I am not sure these will help, as Chrome works fine with the LAN.
Is my IP address the same regardless of using wifi or LAN cable? If so, would changing it help as it works fine on LAN.
However, I will keep trying your suggestions.

You defintely have something wrong though..

so please run ESET with my settings pictured above.. and start the bleeping computer cleanup with the tools I mentioned..

HItmanPRO.. and ESET scanner online.. atleast run those and tell me it says your computer is clean..

Hi, I ran ESET and it found "Win32/Bundled.Toolbar:Google D potentially unsafe application" which was quarantined. The problem still existed after a reboot.
Hitman Pro found nothing.
Net Adapter Repair ran as instructed but no better. Zero sent or received.
However when I ran diagnostics on the wifi connector, this time I got a different message “one or more network protocols are missing on this computer”

I ran MBAM and RogueKiller a couple of days ago and found nothing.

I will carry on and do the rest.

What I would really like to do now is roll back to 8 and do a return to factory settings but I can't because it says 'insert media.... Some files are missing.......your windows installation or recovery media will provide these files'.

Any ideas how to get round that?

Hi, yes I did that a few days ago but the driver was up to date.
One development today though! I tried it on someone else's router on wifi and it worked fine!
All my other stuff works fine on my wifi except this laptop.
I guess I need to contact EE and see if there can be a bad link between laptop and router if that is possible?
Didn't think of trying another wifi before. I think this changes everything doesn't it?

I don't know how many programs and documents you may have to save, but I would save all your things and reformat and clean reinstall windows to be honest..

Look at your first post, you got something.. your definitely infected with something.. I'm sure that could have changed your situation..

Regardless if your wifi worked on another router, then try it again.. see if now it all the sudden "doesn't work" Perhaps whatever you have needs time to infect! haha..

You'll have to save everything though.. Bookmarks etc..

Look at your first post description carefully again.. I would certainly not feel to secure after that..

Point is, whether you are clean or not now, you have still been compromised..

anyway, some setting is set wrong somewhere.. but if it worked with your other "router" something is definitely scary.. It's only "your" router that you can't use??

[FONT=Segoe UI, verdana, Tahoma, Calibri, Verdana, Geneva, sans-serif]I have been using Hotspot Shield for a few years now as it enables me to watch UK TV programmes whilst abroad. When I am in the UK I tend to turn it off as I don't need it so much. [/FONT]It shows up under 'Network Connections' as 'Ethernet 2 Anchorfree HSS VPN Adapter'
[FONT=Segoe UI, verdana, Tahoma, Calibri, Verdana, Geneva, sans-serif]Yesterday I looked at my account and got an error message saying it had encountered a problem. I clicked on the repair now link but noticed it was set to showing me as being in the USA. Out of habit I changed it to UK and my wifi started working !!!!!!!!!!!!!
Absolutely no idea why. I have used HSS for years and being set to other countries is what it is all about! It has never affected the laptop in any way!
I still think I will go back to manufacturers factory settings and start again,
Thanks very much for your input.
