System is Vista Home Prem SP2 on Dell 1.8ghz, 4gb RAM, 32 bit.
Most applications run slow, boots up very slow, most all web sites, regarless of browser, are slow.
I run Malwarebytes scans every other day - nothing reported. Recently did a a defrag. The ESET on line scan found some PDF related problems and fixed them. All of this has given very little improvement.
Please advise what to try next. Thanks.
