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?
