PC has been acting up. Looked into mscofig/startups and a program "svhost.exe -sr -1" was listed twice. SVHOST (not svchost)is supposed to be a virus related item. Unchecked same but was checked again upon opening RUN box. Did not open any programs to cause them to be checked. It was listed in my registry under c:\Windows but when I looked into Explorer it was not there. Here again deleted them but they came right back. Ran a virus check and nothing shows up. Any help.
