I just went through our office managers PC. Installed all the latest Microsoft updates,AVG antivirus update,Spyware/Malware scan and reg clean, HDD defrag, and upgraded her ram. The machine has been running excellent for a week. I came back this evening and after she opened an email from another employee ZAP. All crap breaks loose. The Firewall is turned off,Windows update disabled,Antivirus disabled, Internet explorer won't run, and we can't connect to the internet.It does boot up normal but that is about it. I tried a system restore to a previous point but it won't allow that either. I think a bad virus has grabed it but I'll run a hdd utility in the morning. ANY Ideas or similar experiences?
