The avast web shield warning is repeatedly blocking a “harmful webpage or file”. This goes on if I open my web browser or if I’m offline. The process is always C:\Windows\System32\svchost.exe
I’ve read about svchost viruses on this and other forums and maybe that’s what this is. I’ve tried a number of different malware programs but nothing I’ve done has helped. I may have made things worse by trying to fix it myself. Any suggestions would be appreciated.
