yesterday i found my internet connection very slow, i did a virus scan with microsoft tool and t found several malware and trojans which it removed but said it was only partieally able to remove 2 . so today i installed avast and did a full scan. it found 2 issues which i did an automatic fix on, it then asked me to a reboot scan which i did. half way through i had a power cut. when power resumed PC did a system restore to before ful lscan so i did this again. Same 2 issues found and removed. This time it did not ask for a reboot scan. Problem is that afterwards i no longer had access to internet with my browser, google chrome. I can still get emails, use ipad with same router etc. I have checked all connections, rebooted etc but no luck gaining interent access with google chrome. So.. i have manually done another system restore to before time of scan and browser works again. although still slow. I really dont understand why this is but really want the software to remove the threats. i dont have any other browsers installed. any ideas please?

What did Avast remove ? As some of these adwares add a proxy to the internet connection

Please download Farbar Recovery Scan Tool (http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/) and save it to your Desktop.
Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.
- Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
- Select additions at the bottom
- Press Scan button.
(https://dl.dropboxusercontent.com/u/73555776/frst.JPG)
- It will produce a log called FRST.txt in the same directory the tool is run from.
- Please attach both logs generated.
-
ok here it goes
-
Download the attached Fixlist.txt to the same location as FRST
Run FRST and press Fix
On completion a log will be generated please post that
THEN
Please download AdwCleaner (http://www.bleepingcomputer.com/download/adwcleaner/) by Xplode onto your desktop.
- Close all open programs and internet browsers.
- Double click on AdwCleaner.exe to run the tool.
- Click on Scan.
- After the scan is complete click on "Clean"
- Confirm each time with Ok.
- Your computer will be rebooted automatically. A text file will open after the restart.
- Please post the content of that logfile with your next answer.
- You can find the logfile at C:\AdwCleaner[S1].txt as well.
-
here is the fixlog, will do next step now
-
Once Adwcleaner has finished could you let me know how the system is behaving please
-
here is the next log. system seems to be running more smoothly, not as fast as it usually is but a lot better than previously.
-
OK next we will empty the temp folders and then if you run a disc defrag that should speed you up a bit
[color="#990033"]Clear Cache/Temp Files[/color]
Download TFC by OldTimer (http://oldtimer.geekstogo.com/TFC.exe) to your desktop
- Please double-click TFC.exe to run it. (Note: If you are running on Vista, right-click on the file and choose Run As Administrator).
- It will close all programs when run, so make sure you have saved all your work before you begin.
- Click the Start button to begin the process. Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two. Let it run uninterrupted to completion.
- Once it's finished it should reboot your machine. If it does not, please manually reboot the machine yourself to ensure a complete clean.
-
thank you i haven't run a defrag for ages so I'll let it run overnight. So assuming I'm then up to speed... no need to run another full scan with avast? ok to continue to use avast? no nasty bits still on my PC?
-
Nope. looks nice and clean
Subject to no further problems :)
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean :thumbsup:
A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:
Download and run Delfix (http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/9-delfix)
(https://dl.dropboxusercontent.com/u/73555776/delfix.JPG)
: Keep Java Updated :
WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article (http://www.forbes.com/sites/eliseackerman/2013/01/11/us-department-of-homeland-security-calls-on-computer-users-to-disable-java/) and this article (http://www.nbcnews.com/technology/technolog/us-warns-java-software-security-concerns-escalate-1B7938755).
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser (http://www.geekstogo.com/2600/how-to-disable-java-in-your-web-browser/) and How to unplug Java from the browser (http://krebsonsecurity.com/how-to-unplug-java-from-the-browser/))
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:
CryptoPrevent (http://www.foolishit.com/vb6-projects/cryptoprevent/) install this programme to lock down and prevent crypto ransome ware
(https://dl.dropboxusercontent.com/u/73555776/CryptoPrevent.JPG)
Malwarebytes (http://www.malwarebytes.org/mbam-download.php).
Update and run weekly to keep your system clean
It is critical to have both a firewall and anti virus to protect your system and to keep them updated.
To learn more about how to protect yourself while on the internet read this little guide Best security practices (http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/)Keep safe :wave:

You're an angel :-*
Thank you so much for your help, i'll run those last bits after defrag tomorrow and I'll update how things are running. Sue's world has had peace restored. xx
-
No problem, this was a nice easy one :)
Keep safe, but any further problems then just shout
-
Just a bit of an update. System no longer slow, had some minor problems with google, bookmarks cleared on another PC users profile, and a pop up about preferences not being kept, but all in all feeling safer. Thanks again for your time and help.

Glad to be of assistance :)
