Why would someone need to use tools like iecacheview or mylastsearch on a system? do companies have the right to search a workstation they issued to their employees?

IECacheView helps a user quickly and easily access and read the cache folder of Internet Explorer. Information such as filename, content type, number of hits, expiration time, and the full path of cache filename can be accessed. With all this information, investigators can look at what users are accessing on the web. Anything accessed on IE by an employee at his or her workstation can be searched by the company. This brings us to the question; do companies have the right to search a workstation they issued to their employees using IECacheView?

In my own opinion, I honestly think that it is not right to search an employee’s workstation using IECacheView or any other tool whatsoever. Under the law, employees have reasonable rights to privacy. These rights prevent employers from searching their employees. Unless there is evidence of computer crimes or misconduct, employees have a greater expectation of privacy

i think it could be virus
